Why not install an app?
Many PDF compressor apps on app stores upload your file to their servers, show heavy ads or lock features behind subscriptions. A web app that runs locally avoids all three and takes no storage space.
Frequently asked questions
Does it work on low-end phones?
Yes, though big scans take longer. For very large files, use “Strong” to reduce work, or compress on a computer.
Are my PDFs uploaded to a server?
No. Compression runs entirely inside your browser using JavaScript and WebAssembly-grade libraries. Your file never leaves your device, so confidential documents stay private. You can even disconnect from the internet after the page loads and it keeps working.
