About the Video Compressor

Video files are huge — a few minutes of phone footage can run hundreds of megabytes, too big to email, slow to upload, and quick to fill a drive. Most "free" online compressors make you upload that footage to their servers, sit in a queue, and accept a file-size cap or a watermark. This one is different: it compresses your video entirely inside your browser, so there's no upload, no size limit imposed by us, and nothing to wait in line for.

Under the hood it runs FFmpeg — the same engine professional video tools are built on — compiled to WebAssembly so it executes locally on your machine. Your video is read straight from disk into the page and never sent anywhere.

How to use it

What to expect

Why on-device matters

Footage is personal — family moments, client work, unreleased content. Uploading it to an unknown server to "compress for free" means handing over a copy you can't get back. Compressing locally keeps your video yours: it goes from your drive, through your browser, back to your drive.

No account, no upload, no watermark — drop it in, compress, download.
