Need to cut out a long intro, remove dead air at the end, or extract a highlight clip from a longer recording? Resizor lets you trim video online without installing any software or uploading your footage to a third-party server. Just open the tool in your browser, load your video, and drag the timeline handles to set your trim points.

The trimming and encoding happen locally on your device using the WebCodecs API, which leverages hardware video acceleration for fast, high-quality output. You can trim MP4, MOV, WebM files and export the result as an H.264 MP4 ready to share anywhere. It's completely free — no registration, no watermark, no file-size limits.

Frequently Asked Questions

Can I trim a video without re-encoding it?

Most browser-based tools, including Resizor, re-encode the video to ensure accurate frame-level cuts. Hardware acceleration via WebCodecs makes this process fast, but for very long videos a lossless trim tool may be faster if exact keyframe boundaries are acceptable.

What video formats can I trim?

Resizor accepts any video format that your browser can decode — typically MP4, WebM, MOV, and sometimes MKV and AVI depending on your browser and OS.

Will my trimmed video lose quality?

Quality loss during trimming is minimal. Resizor uses high-quality H.264 encoding for the output. If you choose a high bitrate setting, the output quality will be visually identical to the source.

Can I trim a video to share on social media?

Yes. After trimming you can also apply a platform preset (Instagram, TikTok, YouTube Shorts) to resize the clip to the correct dimensions in one pass.

Is there a maximum video length I can trim?

Resizor has no enforced length limit, but very long videos (multi-hour recordings) may require significant browser memory. For typical social media and web content there is no practical limit.
