List of Chromium Command Line Switches (for 2017-03-31)
There are lots of command lines which can be used with the Google Chrome browser. Some change behavior of features, others are for debugging or experimenting. This page lists the available switches including their conditions and descriptions. Last automated update occurred on 2024-12-01.
| Condition | Explanation |
|---|---|
| --/prefetch:1[1] ⊗ | /prefetch:# arguments to use when launching various process types. It has been observed that when file reads are consistent for 3 process launches with the same /prefetch:# argument, the Windows prefetcher starts issuing reads in batch at process launch. Because reads depend on the process type, the prefetcher wouldn't be able to observe consistent reads if no /prefetch:# arguments were used. Note that the browser process has no /prefetch:# argument; as such all other processes must have one in order to avoid polluting its profile. Note: # must always be in [1, 8]; otherwise it is ignored by the Windows prefetcher. ↪ Removed on 2024-01-07. This switch was listed in content/public/common/content_switches.cc. |
| --/prefetch:2[1] ⊗ | No description ↪ Removed on 2024-01-07. This switch was listed in content/public/common/content_switches.cc. |
| --/prefetch:3[1] ⊗ | No description ↪ Removed on 2024-01-07. This switch was listed in content/public/common/content_switches.cc. |
| --/prefetch:4[1] ⊗ | No description ↪ Removed on 2024-01-07. This switch was listed in content/public/common/content_switches.cc. |
| --/prefetch:5[1] ⊗ | /prefetch:# arguments for the browser process launched in background mode and as documented in prefetch_type_win.h. ↪ Removed on 2024-04-29. This switch was listed in chrome/common/chrome_switches.cc. |
| --/prefetch:6[2] ⊗ | No description ↪ Removed on 2022-08-14. This switch was listed in chrome/common/chrome_switches.cc. |
| --/prefetch:8[1] ⊗ | /prefetch:# argument shared by all process types that don't have their own. It is likely that the prefetcher won't work for these process types as it won't be able to observe consistent file reads across launches. However, having a valid prefetch argument for these process types is required to prevent them from interfering with the prefetch profile of the browser process. ↪ Removed on 2024-01-07. This switch was listed in content/public/common/content_switches.cc. |

| --mem-pressure-system-reserved-kb ⊗ | Some platforms typically have very little 'free' memory, but plenty is available in buffers+cached. For such platforms, configure this amount as the portion of buffers+cached memory that should be treated as unavailable. If this switch is not used, a simple pressure heuristic based purely on free memory will be used. ↪ |

| --metrics-recording-only ⊗ | Enables the recording of metrics reports but disables reporting. In contrast to kForceEnableMetricsReporting, this executes all the code that a normal client would use for reporting, except the report is dropped rather than sent to the server. This is useful for finding issues in the metrics code during UI and performance tests. ↪ |
| --mhtml-generator-option ⊗ | Sets options for MHTML generator to skip no-store resources: "skip-nostore-main" - fails to save a page if main frame is 'no-store' "skip-nostore-all" - also skips no-store subresources. ↪ Removed on 2019-08-13.

| --nacl-dangerous-no-sandbox-nonsfi ⊗ | Disable sandbox even for non SFI mode. This is particularly unsafe as non SFI NaCl heavily relies on the seccomp sandbox. ↪ Removed on 2022-08-14. This switch was listed in components/nacl/common/nacl_switches.cc. |
| --nacl-debug-mask ⊗ | Uses NaCl manifest URL to choose whether NaCl program will be debugged by debug stub. Switch value format: [!]pattern1,pattern2,...,patternN. Each pattern uses the same syntax as patterns in Chrome extension manifest. The only difference is that * scheme matches all schemes instead of matching only http and https. If the value doesn't start with !, a program will be debugged if manifest URL matches any pattern. If the value starts with !, a program will be debugged if manifest URL does not match any pattern. ↪ |

| --no-experiments ⊗ | Disables all experiments set on about:flags. Does not disable about:flags itself. Useful if an experiment makes chrome crash at startup: One can start chrome with --no-experiments, disable the problematic lab at about:flags and then restart chrome without this switch again. ↪ |
| --no-first-run ⊗ | Skip First Run tasks as well as not showing additional dialogs, prompts or bubbles. Suppressing dialogs, prompts, and bubbles is important as this switch is used by automation (including performance benchmarks) where it's important only a browser window is shown. This may not actually be the first run or the What's New page. Overridden by kForceFirstRun (for FRE) and kForceWhatsNew (for What's New). This does not drop the First Run sentinel and thus doesn't prevent first run from occurring the next time chrome is launched without this flag. It also does not update the last What's New milestone, so does not prevent What's New from occurring the next time chrome is launched without this flag. ↪ |
| --no-managed-user-acknowledgment-check ⊗ | Disables checking whether we received an acknowledgment when registering a supervised user. Also disables the timeout during registration that waits for the ack. Useful when debugging against a server that does not support notifications. ↪ Removed on 2022-08-14.

| --no-service-autorun ⊗ | Disables the service process from adding itself as an autorun process. This does not delete existing autorun registrations, it just prevents the service from registering a new one. ↪ |
| --no-startup-window ⊗ | Does not automatically open a browser window on startup (used when launching Chrome for the purpose of hosting background apps). ↪ |
| --no-use-mus-in-renderer ⊗ | Do not use the mojo UI Service in the Chrome render process. ↪ Removed on 2017-07-01. This switch was listed in content/public/common/content_switches.cc. |
| --no-wifi ⊗ | Disable features that require WiFi management. ↪ Removed on 2022-08-14. This switch was listed in chromecast/base/chromecast_switches.cc. |
| --no-zygote ⊗ | Disables the use of a zygote process for forking child processes. Instead, child processes will be forked and exec'd directly. Note that --no-sandbox should also be used together with this flag because the sandbox needs the zygote to work. ↪ |
| --noerrdialogs ⊗ | Suppresses all error dialogs when present. ↪ |
| --non-material ⊗ | Classic, non-material, mode for the |kTopChromeMD| switch. ↪ Removed on 2019-08-13. This switch was listed in ui/base/ui_base_switches.cc. |

| --top-chrome-md ⊗ | Enables top Chrome material design elements. ↪ Removed on 2019-08-13. This switch was listed in ui/base/ui_base_switches.cc. |
| --top-controls-hide-threshold ⊗ | Percentage of the browser controls need to be hidden before they will auto hide. ↪ |
| --top-controls-show-threshold ⊗ | Percentage of the browser controls need to be shown before they will auto show. ↪ |
| --top-document-isolation ⊗ | Groups all out-of-process iframes to a different process from the process of the top document. This is a performance isolation mode. ↪ Removed on 2017-07-01. This switch was listed in content/public/common/content_switches.cc. |
| --touch-calibration[31] ⊗ | The calibration factors given as "<left>,<right>,<top>,<bottom>". ↪ Removed on 2020-07-28. This switch was listed in ui/events/event_switches.cc. |
| --touch-devices[17] ⊗ | Tells chrome to interpret events from these devices as touch events. Only available with XInput 2 (i.e. X server 1.8 or above). The id's of the devices can be retrieved from 'xinput list'. ↪ |
| --touch-events ⊗ | Enable support for touch event feature detection. ↪ |
| --touch-noise-filtering[31] ⊗ | Tells Chrome to do additional touch noise filtering. Should only be used if the driver level filtering is insufficient. ↪ Removed on 2020-07-28. This switch was listed in ui/events/event_switches.cc. |
| --touch-selection-strategy ⊗ | Controls how text selection granularity changes when touch text selection handles are dragged. Should be "character" or "direction". If not specified, the platform default is used. ↪ |
| --trace-config-file ⊗ | Causes TRACE_EVENT flags to be recorded from startup. This flag will be ignored if --trace-startup or --trace-shutdown is provided. ↪ |
| --trace-export-events-to-etw[2] ⊗ | Enables the exporting of the tracing events to ETW. This is only supported on Windows Vista and later. ↪ Removed on 2019-08-13. This switch was listed in content/public/common/content_switches.cc. |
| --trace-shutdown ⊗ | Causes TRACE_EVENT flags to be recorded beginning with shutdown. Optionally, can specify the specific trace categories to include (e.g. --trace-shutdown=base,net) otherwise, all events are recorded. --trace-shutdown-file can be used to control where the trace log gets stored to since there is otherwise no way to access the result. ↪ Removed on 2019-08-13. This switch was listed in components/tracing/common/tracing_switches.cc. |
| --trace-shutdown-file ⊗ | If supplied, sets the file which shutdown tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-shutdown is also supplied. Example: --trace-shutdown --trace-shutdown-file=/tmp/trace_event.log ↪ Removed on 2019-08-13. This switch was listed in components/tracing/common/tracing_switches.cc. |
| --trace-startup ⊗ | Causes TRACE_EVENT flags to be recorded from startup. Optionally, can specify the specific trace categories to include (e.g. --trace-startup=base,net) otherwise, all events are recorded. Setting this flag results in the first call to BeginTracing() to receive all trace events since startup. Historically, --trace-startup was used for browser startup profiling and --enable-tracing was used for browsertest tracing. Now they are share the same implementation, but both are still supported to avoid disrupting existing workflows. The only difference between them is the default duration (5 seconds for trace-startup, unlimited for enable-tracing). If both are specified, 'trace-startup' takes precedence. In Chrome, you may find --trace-startup-file and --trace-startup-duration to control the auto-saving of the trace (not supported in the base-only TraceLog component). ↪ |
| --trace-startup-duration ⊗ | Sets the time in seconds until startup tracing ends. If omitted: - if --trace-startup is specified, a default of 5 seconds is used. - if --enable-tracing is specified, tracing lasts until the browser is closed. Has no effect otherwise. ↪ |
| --trace-startup-file ⊗ | If supplied, sets the file which startup tracing will be stored into, if omitted the default will be used "chrometrace.log" in the current directory. Has no effect unless --trace-startup is also supplied. Example: --trace-startup --trace-startup-file=/tmp/trace_event.log As a special case, can be set to 'none' - this disables automatically saving the result to a file and the first manually recorded trace will then receive all events since startup. ↪ |
| --trace-to-console ⊗ | Sends a pretty-printed version of tracing info to the console. ↪ |
| --trace-to-file ⊗ | Sends trace events from these categories to a file. --trace-to-file on its own sends to default categories. ↪ |
| --trace-to-file-name ⊗ | Specifies the file name for --trace-to-file. If unspecified, it will go to a default file name. ↪ |
| --trace-upload-url ⊗ | Sets the target URL for uploading tracing data. ↪ Removed on 2022-08-14. This switch was listed in components/tracing/common/tracing_switches.cc. |
| --translate-ranker-model-url ⊗ | Overrides the URL from which the translate ranker model is downloaded. ↪ |
| --translate-script-url ⊗ | Overrides the default server used for Google Translate. ↪ |

| --true ⊗ | Value indicating whether flag from command line switch is true. ↪ |
| --try-chrome-again ⊗ | Experimental. Shows a dialog asking the user to try chrome. This flag is to be used only by the upgrade process. ↪ Removed on 2023-10-08. This switch was listed in chrome/common/chrome_switches.cc. |
| --try-supported-channel-layouts[1] ⊗ | Instead of always using the hardware channel layout, check if a driver supports the source channel layout. Avoids outputting empty channels and permits drivers to enable stereo to multichannel expansion. Kept behind a flag since some drivers lie about supported layouts and hang when used. See http://crbug.com/259165 for more details. ↪ Removed on 2023-12-10. This switch was listed in media/base/media_switches.cc. |
| --type ⊗ | Flags spied upon from other layers. ↪ |
| --ui-disable-partial-swap ⊗ | Disable partial swap which is needed for some OpenGL drivers / emulators. ↪ |

| --unsafe-pac-url ⊗ | Pass the full https:// URL to PAC (Proxy Auto Config) scripts. As opposed to the default behavior which strips path and query components before passing to the PAC scripts. ↪ Removed on 2019-08-13. This switch was listed in chrome/common/chrome_switches.cc. |
| --unsafely-treat-insecure-origin-as-secure ⊗ | Treat given (insecure) origins as secure origins. Multiple origins can be supplied as a comma-separated list. For the definition of secure contexts, see https://w3c.github.io/webappsec-secure-contexts/ and https://www.w3.org/TR/powerful-features/#is-origin-trustworthy Example: --unsafely-treat-insecure-origin-as-secure=http://a.test,http://b.test ↪ |
| --use-angle ⊗ | Select which ANGLE backend to use. Options are: default: Attempts several ANGLE renderers until one successfully initializes, varying ES support by platform. d3d9: Legacy D3D9 renderer, ES2 only. d3d11: D3D11 renderer, ES2 and ES3. warp: D3D11 renderer using software rasterization, ES2 and ES3. gl: Desktop GL renderer, ES2 and ES3. gles: GLES renderer, ES2 and ES3. ↪ |

| --use-fake-ui-for-media-stream ⊗ | Bypass the media stream infobar by selecting the default device for media streams (e.g. WebRTC). Works with --use-fake-device-for-media-stream. Prefer --auto-accept-camera-and-microphone-capture which does not interact with screen/tab capture. ↪ |
| --use-file-for-fake-audio-capture ⊗ | Play a .wav file as the microphone. Note that for WebRTC calls we'll treat the bits as if they came from the microphone, which means you should disable audio processing (lest your audio file will play back distorted). The input file is converted to suit Chrome's audio buses if necessary, so most sane .wav files should work. You can pass either <path> to play the file looping or <path>%noloop to stop after playing the file to completion. Must also be used with kDisableAudioInput or kUseFakeDeviceForMediaStream. ↪ |
| --use-file-for-fake-video-capture ⊗ | Use an .y4m file to play as the webcam. See the comments in media/capture/video/file_video_capture_device.h for more details. ↪ |

| --use-gl ⊗ | Select which implementation of GL the GPU process should use. Options are: desktop: whatever desktop OpenGL the user has installed (Linux and Mac default). egl: whatever EGL / GLES2 the user has installed (Windows default - actually ANGLE). swiftshader: The SwiftShader software renderer. ↪ |
| --use-gpu-in-tests ⊗ | Use hardware gpu, if available, for tests. ↪ |

| --use_new_features_summary[7] ⊗ | Forces the new features summary to be displayed below the update menu item. ↪ Removed on 2017-07-01. This switch was listed in chrome/common/chrome_switches.cc. |
| --utility ⊗ | No description ↪ |
| --utility-allowed-dir ⊗ | When utility process is sandboxed, there is still access to one directory. This flag specifies the directory that can be accessed. ↪ Removed on 2019-08-13. This switch was listed in content/public/common/content_switches.cc. |
| --utility-cmd-prefix ⊗ | The contents of this flag are prepended to the utility process command line. Useful values might be "valgrind" or "xterm -e gdb --args". ↪ |
