About FreeCompress

What this is

freecompress.video is a video compressor, plus the handful of small video jobs that usually come with one: trimming a clip, removing the sound, pulling the audio out as MP3, rotating a sideways recording, saving a frame as an image. Every tool is available in every language the site supports.

Every tool runs inside your browser. When you drop a video in, it is read from your disk, decoded and re-encoded by your own device — using the same hardware video encoder that recorded it — and the result is written back to your disk. The library that does the container work is mediabunny; the encoding is your browser's WebCodecs implementation. There is no upload, no queue, no account and no size limit, because there is no server doing the work that could need any of those.

Who we are

One engineer with a long background in cross-platform and network software, building this the way the desktop tools used to be built: one thing, done properly, kept working for years. There is no support desk, but there is a person who reads every message sent through the contact page and fixes things when they are broken.

The tools are free and unlimited; the site is supported by the ads on the page. We do not sell anything, collect e-mail addresses, or run affiliate links. The privacy policy says exactly what is measured and by whom.

Why it is built this way

Upload-based video compressors charge for large files because bandwidth and server time cost them money. Moving the work into the browser removes that cost entirely, which is what makes "no size limit" and "free" honest rather than a free-tier hook. It also makes the privacy claim verifiable: open your browser's network panel while a compression runs and there is no request carrying the video.

Each tool is meant to match the best desktop equivalent, not merely to work. The compressor measures quality in bits per pixel so the same setting gives the same look at any resolution; it lowers resolution only when a size target cannot be met cleanly, and it tells you before it does. If you find a case where it does a poor job, tell us — that is how most improvements here start.

Known issues

Hardware encoding depends on the browser and device. Chrome and Edge offer the most codecs; Safari 17+ works on Mac and iPhone; Firefox encodes H.264 and VP9 but may not decode HEVC. AVI, WMV, FLV and other legacy containers need a software compatibility engine that is not enabled by default. Very old phones may lack a hardware encoder altogether, in which case the browser refuses and the page says so.
