FAQ
How does the video trimmer work?
FFmpeg WebAssembly runs in your browser to cut your video at the exact timestamps you specify. No data is uploaded — everything processes locally on your device.
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 entirely in your browser via WebAssembly. Your video never leaves your device.
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="/ai/video/mp4-to-mp3">MP4 to MP3</a>. Want a GIF instead? Use <a href="/ai/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 (transitions, effects, multi-track). Our advantage: zero installation, complete privacy, and instant access from any browser.
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. Completely free, no limits, no signup required.
Can I pay with cryptocurrency?
