Convert, compress, trim, merge — 32 tools powered by ffmpeg in your browser.
Uploading video to a cloud tool takes forever and exposes your footage. fwip runs ffmpeg.wasm directly in your browser — convert MOV to MP4, compress for email, trim clips, extract audio, and more. Your video never leaves your device.
Video files are big, awkward, and format-dependent. MOV files from your iPhone won't play on half the devices out there. MKV files won't open in most editors. Uncompressed clips are too large for email, WhatsApp, or Slack.
fwip handles format conversion, compression, trimming, merging, rotating, resizing, speed changes, subtitle burning, audio extraction, and GIF creation. Everything runs on ffmpeg.wasm — the same engine professionals use, compiled to run in your browser.
Container swaps (MOV to MP4, MKV to MP4) complete in seconds because there's no re-encoding. Compression and editing re-encode with H.264 for maximum compatibility.
Compress for email, WhatsApp, or Slack.
Uploading a 500MB video file to a cloud converter takes minutes on a good connection. Then it processes on their server. Then you download the result. That's three bottlenecks, plus your footage sitting on someone else's machine.
fwip runs ffmpeg.wasm in your browser tab. For container swaps like MOV to MP4, the conversion takes seconds because there's no re-encoding — it just repackages the streams. For compression and editing, it re-encodes locally with H.264. Your video never touches a server.
The offline bundle handles batch jobs and removes all file size limits. Process an entire shoot locally.
