Questions
What people ask before they use this tool.
How does the video trimmer work?
FFmpeg WebAssembly runs in your browser to cut your video at the timestamps you specify. Source files are processed locally during trimming and are not uploaded to our servers.
What video formats are supported?
MP4, MOV, AVI, MKV, WebM, and most common video formats. Output is always MP4 (H.264) for maximum compatibility.
Is there a file size limit?
Processing happens in your browser, so it depends on your device memory. Most devices handle videos up to 500MB-1GB. Longer videos take more time.
Can I trim to exact seconds?
Yes — set start and end time with 0.5-second precision using the input fields. The video preview updates as you change the timestamps.
Does trimming re-encode the video?
Yes, using H.264 encoding for clean cuts. This means exact-frame precision but takes a bit longer than stream copying. Quality loss is negligible.
Is my video uploaded to a server?
No. FFmpeg runs in your browser via WebAssembly. Source video files are processed locally during trimming and are not uploaded to our servers.
Why does the first trim take longer?
The FFmpeg WebAssembly engine (~31MB) downloads on first use. After that it is cached — subsequent trims start instantly.
Can I trim multiple segments?
Currently one segment per operation. Trim once, download, then upload again for additional cuts.
Does it preserve audio?
Yes. Both video and audio tracks are preserved. Need just the audio? Try <a href="/mp4-to-mp3">MP4 to MP3</a>. Want a GIF instead? Use <a href="/video-to-gif">Video to GIF</a>.
Does it work on mobile?
Yes, for shorter videos. Video processing is CPU-intensive — for longer videos, use a desktop browser.
Can I preview before downloading?
Yes. After trimming, the result plays in a video player so you can verify the cut before downloading.
How does this compare to iMovie or Premiere?
Desktop editors offer more features such as transitions, effects, and multi-track editing. This browser tool is a lighter option when you want a quick trim without installing desktop software.
What is the output format?
MP4 with H.264 video and AAC audio — the most universally compatible format. Works on every device and platform.
Is it really free?
Yes. The browser tool is free to use, and signup is not required to start.
Can I pay with cryptocurrency?
