tips & examples

Getting the best results

Fast vs. precise

Fast mode copies the original data, so it's instant and lossless, but can only cut at keyframes. Use Precise when the exact first frame matters.

Trim before resizing

Cut your clip first, then convert it to 9:16 in the Video Resizer. Processing a shorter clip is much faster.

Phones and big files

Browser video processing uses a lot of memory. On phones, stick to short clips; on a computer, files up to 500 MB are supported.

Video Trimmer questions

Can I trim an MP4 without re-encoding or losing quality?

Yes. Choose Fast (no re-encode): the original video and audio data are copied as-is, so there is no quality loss and it finishes almost instantly. The only trade-off is that the cut starts on the nearest keyframe.

Does trimming reduce video quality?

Fast mode doesn't touch quality at all. Precise mode re-encodes with high-quality H.264 settings, which is visually very close to the original.

Why is my fast-mode clip slightly longer than selected?

Without re-encoding, a cut can only start on a keyframe, so the clip may begin a little before your start time. Use Precise mode for an exact cut.

Which formats are supported?

MP4, MOV, WebM and MKV with common codecs such as H.264, VP8/VP9 and AAC. Some iPhone HEVC or ProRes files can't be decoded in the browser; you'll see a clear message if that happens. Precise mode always outputs MP4.

Can I cancel a long job?

Yes. Select Cancel at any time; processing stops immediately and your settings are kept.

Can I download videos from YouTube or TikTok with this?

No. This tool only edits video files you already have on your device. Only use content you own or have permission to edit.
