Why this matters
MP4 is the universal format. Every device, every browser, every social platform, every video player accepts it. But cameras shoot MOV, screen recorders output MKV or WebM, old files are AVI or WMV. Converting should be simple — and it shouldn’t require handing your footage to a website.
Most online converters upload your video, process it on their servers (sometimes taking minutes for large files), then offer a download — often behind a paywall or with a watermark. fwip uses FFmpeg compiled to WebAssembly. Your video stays local.
Frequently asked questions
What video formats can fwip convert? MOV, AVI, MKV, WebM, FLV, WMV, 3GP, OGV, and more. Essentially anything FFmpeg supports — which is nearly everything.
Is there a file size limit? Browser processing depends on your device’s memory. Files up to 500MB–1GB work on most modern machines. The desktop app handles larger files more reliably.
Does converting to MP4 reduce quality? With default settings, quality loss is negligible. fwip uses sensible encoding defaults that balance file size and quality. You can adjust settings in the desktop app for more control.
How long does conversion take? Depends on the file size and your device. A 100MB video typically converts in 10–30 seconds on a modern laptop. Longer videos take longer — but it’s all happening locally, so there’s no upload/download wait.
Can I convert multiple videos at once? The desktop app supports batch conversion. In the browser, one file at a time.
