Frequently asked questions

Is my video uploaded?

No. The trimmer reads the file inside your browser and writes the result on your device. Nothing is sent to our servers, so it also works for private videos.

Does trimming reduce quality?

Not in fast mode: it copies the original video and audio data without re-encoding. Precise mode re-encodes the clip, which can lose a little quality but cuts on the exact frame.

Why does fast mode sometimes start a moment early?

Video is stored in groups of frames that begin with a keyframe. Fast mode keeps the keyframe before your start point and tells players to begin at your exact time; a few players ignore that and show the extra frames. Use precise mode if you need an exact cut everywhere.

Is there a file size limit?

On a computer you can open videos up to 4 GB. Phones have less memory, so the limit there is 1 GB. If a large file fails on your phone, try it on a computer.

Which formats are supported?

You can open MP4, MOV, M4V, WebM and MKV files. The result is saved as MP4, which plays on almost every device and platform.
