How do I shrink a PDF that is too heavy to email?
Drop the file and pick a compression level. Images are what weigh: they are re-encoded at a lower resolution, while text stays sharp.
Compress PDF
Shrink a PDF so you can send it by email.
Two modes: a lossless pass that keeps text selectable, or a heavy pass that turns pages into images. The second shrinks more, but text stops being text — we show you the gain before you download.

Common questions
Are my files uploaded to the internet?
No. This tool runs entirely in your browser: the document is opened on your device, processed there, and never sent anywhere. You can even go offline once the page has loaded.
Will quality drop?
Image quality will — that is the point. Text and vector artwork are untouched and stay perfectly legible in print. Compare the result before keeping it.
Is it free, and do I need an account?
Free and unlimited, with no account and no sign-up. This tool costs us nothing because it runs on your machine, so we have no reason to ration it.
