Shrink big scans and image-heavy PDFs so they fit through email limits and upload forms. Pick how small, then download.
Heads up. This tool turns each page into an image to shrink it, so text in the compressed file won’t be selectable or searchable, and links stop working. Keep your original if you need those.
Drop in the file that’s too big.
Small file for email, Balanced for most things, Better quality if it’ll be printed.
See how much smaller it got, then save it.
Good to know. This works best on scans and image-heavy PDFs, where it often cuts the size by 70% or more. A PDF that’s mostly plain text is usually small already and may not shrink, in which case keep your original.
No. The tool runs entirely in your browser using open-source libraries, so your file never leaves your device. You can even disconnect from the internet once the page has loaded and it’ll still work.
To shrink the file, each page is redrawn as a compressed picture. That’s what makes it smaller, but it also means the text is now part of an image rather than real text.
Balanced suits most emails and online forms. Use Small file if there’s a strict limit, like 2 MB, and Better quality if someone will print it.
If the original is mostly text or already optimised, turning it into images can add weight. The tool tells you when that happens, so just keep the original.
