Make your PDF smaller.
Shrink a PDF to fit an upload limit — job applications, forms, email attachments. It all happens in your browser; your file never leaves your device.
Compress PDF
Reduce a PDF’s file size — great for getting under a 2 MB (or smaller) upload limit. Text
stays selectable, and you choose how hard to compress.
In your browser
Files are processed locally with WebAssembly. Nothing is ever uploaded.
No tracking
No analytics, no cookies, no third-party scripts. You are not the product.
Free & open
No account, no limits, no ads. Just tools that run on your machine.
