FAQ
What can this tool do?+
Trim, rotate (90/180/270, horizontal/vertical flip), change speed (0.25–3x), mute, change resolution (240p–1080p), and compress (CRF 18–33). Multiple operations can stack.
Does stacking operations hurt quality more?+
Actually less. Running separate tools means re-encoding multiple times; this single tool finishes everything in one ffmpeg pass, minimizing loss.
What if I just need one operation?+
The individual tools ([video trim], [video rotate], [video compress], etc.) still exist with simpler UIs.
What about format conversion, merging, or GIFs?+
This tool focuses on single-video editing. For MP3/GIF conversion, merging, or info inspection, use the dedicated tools ([video to MP3], [video merge], [video info]).
How long does processing take?+
Operations that need re-encoding (everything except trim) take 1–2x the video length. Trim alone uses stream copy and is very fast.
Why is the first ffmpeg.wasm download slow?+
First run downloads the ffmpeg.wasm core (~25MB). After that, it's cached and runs immediately. Everything happens in your browser — videos are never transmitted.
