Shrink a large PDF so it fits an email or upload limit, without sending your document anywhere. Compression runs entirely in your browser, so the file is never sent to our servers.
Yes. Unlike most “compress PDF online” tools, PaperFit never uploads your file to our servers. The whole process happens on your own device using your browser, so a confidential contract, statement, or ID stays with you. You can confirm it: open your browser’s network tab and watch — your file is never uploaded to our servers while you compress.
No. Compression runs 100% in your browser. Your PDF is never sent to our servers, so there is nothing for us to see, store, or leak.
PaperFit aims for the smallest size that keeps your document readable. Choose the higher-quality preset to favour sharpness, or a target size to favour a smaller file.
You can compress PDFs up to 200 MB. Because everything runs locally, very large files depend on your device’s available memory.
No — if compression would not actually reduce the size, PaperFit keeps your original instead of handing back a larger file.
No. It works in any modern browser with no account, no extension, and no software to install.
Yes. It runs in mobile browsers too, though very large files are limited by phone memory.
