What video formats are supported?

You can use MP4, MOV, AVI, WebM, MKV and other common video files.

Is Video Trimmer really free?

Yes. You can use this free video tool without making an account.

Are my videos uploaded to your servers?

Most quick tools run in your browser. If a tool says it uses a pro server option, it will tell you before you use that option.

What browser should I use?

Chrome and Edge work best for video tools. Most image tools also work well in Safari and Firefox.

Does trimming reduce video quality?

Usually no. This tool copies the original video and audio data when the container allows it, so quality stays the same. It only re-encodes if a copy is impossible for that file.

Can I trim to an exact second if it is not on a keyframe?

Yes. Stream copy can keep the requested start and end times even when the nearest video keyframe sits outside that range. MP4 uses edit lists for this.

Is this a video cutter as well as a trimmer?

Yes. Cut video online by setting a start and end time. The same tool covers trim, shorten, and cutter searches for MP4, MOV, WebM, and MKV.

Can I trim a video for Instagram, WhatsApp, or TikTok?

Yes. Cut a clip to the length those apps allow, then download it. Processing stays on your device.

Can I trim multiple sections?

Currently you can trim one continuous section. For multiple cuts, trim multiple times or use our full video editor.
