About

ShrinkVid is a free browser-based video compressor. It exists to solve one recurring annoyance: hitting an upload limit — Discord's 10 MB, WhatsApp's 16 MB, an email server's 25 MB — and having no quick way to get under it without either re-recording or handing the file to a third-party server.

How it works

The site is a static page. There is no backend that receives video. When you pick a file, your browser reads it from disk, hands the bytes to FFmpeg compiled to WebAssembly, runs the encode on your own CPU, and gives you a download link backed by memory. Nothing is uploaded because there is nowhere to upload it to.

That architecture has trade-offs worth stating plainly. Large files are limited by your device's memory, not by a server quota — a phone will struggle where a laptop will not. Speed depends on your hardware. In exchange, nothing about your video ever leaves your machine, and the site costs almost nothing to run, which is why it can stay free.

What it costs

Nothing. There is no account, no quota and no watermark. The site is supported by advertising, which is the only reason ads appear on the page.

Who runs it

An independent developer. Questions, bug reports and feature requests are welcome through the contact page.
