Frequently asked questions
Is there a limit to how many PDFs I can batch compress?
No hard limit. Very large batches just take longer, and your device's memory is the practical ceiling.
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.
