Frequently Asked Questions

Is my video uploaded to a server?

No. All trimming happens in your browser. Your video files never leave your device. You can also extract the audio from the trimmed result.

What video formats are supported?

MP4, WebM, MOV, AVI, and MKV are supported. The output format matches the input for maximum compatibility.

Does trimming reduce video quality?

No. When possible, the tool trims without re-encoding, preserving the original quality exactly.

Can I trim long videos?

Yes. The practical limit depends on your device's memory. Most modern devices handle videos up to several GB.

Can I select precise start and end times?

Yes. Use the timeline scrubber or enter exact timestamps for frame-accurate trimming.

Does this work on my phone?

Yes. The tool runs entirely in your browser on any device, including smartphones and tablets.

Is the audio preserved when trimming?

Yes. Both video and audio tracks are trimmed together, keeping them perfectly synchronized.

Can I trim multiple segments from one video?

Currently the tool trims a single continuous segment. For multiple segments, trim each one separately and use the merge tool to combine them.

What is keyframe trimming?

Keyframe trimming cuts at the nearest keyframe boundary, allowing instant lossless trimming without re-encoding. For exact frame cuts, enable re-encoding mode.

Can I trim a 4K video in my browser?

Yes. Since stream-copy mode does not re-encode, even 4K videos can be trimmed quickly on most devices.

Why is the trimmed video slightly longer or shorter than expected?

In lossless mode, the tool trims at the nearest keyframe, which may add a fraction of a second. For exact cuts, enable re-encoding mode.

Can I trim videos recorded on my phone?

Yes. Phone recordings in MP4 or MOV format are fully supported. After trimming, convert the video to change the format if needed.

Tips & Best Practices

Use the timeline scrubber for rough selection, then fine-tune with exact timestamps for precision.

Preview the selected segment before trimming to ensure you captured the right section.

Keep the original file as a backup — trimming creates a new file and does not modify the source.

For social media clips, aim for 15-60 seconds — then compress the video to reduce file size before uploading.

How It Works — 100% Private Processing
