Why we built SimpleSize: your files shouldn't have to leave your browser.

We were tired of file-compression sites that force an account, cap your file size, or quietly upload your documents to a server. So we built one that runs the compression locally in your browser and asks for nothing in return.

1. 2025 Shipped
   A compressor with no upload, no signup, no catch Compress and convert images, video, audio, and PDFs entirely in your browser, with nothing uploaded and no account required.
2. Now In progress
   A rebrand and a closer look at what people actually use We just gave SimpleSize a proper visual identity and are now instrumenting real usage tracking so we know which tools people reach for most.
3. Next Goal

This tool is one of several products built by the same small team, under RapidFoundry. Same rules everywhere: free where we can make it free, and nothing about you sold to anyone.
