Video Trimmer and MP3 Converter
Trim a short video, turn it into MP3 audio, or shrink it for WhatsApp or email. Everything runs in your browser.
Before you start: first use downloads ~30 MB and needs a few seconds. That is the video engine loading in your browser. Your video stays in your browser and is not uploaded to our server.
Best for short clips. For best results, use a file under ~200 MB. Longer or very large videos may be slow or may fail on some devices.
Trim keeps the same video quality and cuts only the part you selected.

Frequently Asked Questions
Why does the first use take a few seconds?
The first use downloads ~30 MB and needs a few seconds because that is when the video engine loads in your browser. After that first load, later uses in the same session do not need to download it again.
Is my video uploaded to a server?
No. Your video stays in your browser while it is trimmed, converted, or compressed. Only the video engine code is loaded from a CDN on first use.
Which video formats can I use?
MP4, MOV, and WebM. You can trim a video, extract MP3 audio from it, or compress it. MP3 output contains audio only; the video picture is removed.
What happens if the WhatsApp version is still over 16 MB?
The WhatsApp preset is best-effort. It tries smaller sizes in turn, and if the smallest version is still over 16 MB, the tool says so plainly and shows the real file size. It never claims a file fits when it does not. Try a shorter clip in that case.
Does trimming reduce the video quality?
No. Trimming keeps the same video quality and cuts only the part you selected. Compression for WhatsApp or email is the separate step that reduces size, and the tool shows the real output size after processing.
