List of Chromium Command Line Switches (for 2016-03-10)
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 2024-05-05.
| 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. |

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.

| --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. |

| --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. ↪ |

| --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-gpu-in-tests ⊗ | Use hardware gpu, if available, for tests. ↪ |
| --use-gpu-memory-buffers-for-capture ⊗ | Use GpuMemoryBuffers for Video Capture when this is an option for the device. Experimental, see http://crbug.com/503835 and http://crbug.com/440843. ↪ Removed on 2016-10-08. This switch was listed in media/base/media_switches.cc. |
