Compress a PDF — make it smaller, free

Shrink a bulky PDF so it's easy to email or upload — no sign-up, no watermark.

Compress a PDF

Upload a PDF — get a smaller file back, no quality settings to fuss with.

Powered by dojobase
Drop a PDF and we'll recompress the images inside it and re-save it as a smaller file. Scanned documents and image-heavy PDFs shrink the most — often dramatically. No account, nothing to install, and if we can't make it smaller you just get your original back.

Frequently asked questions

How much smaller will my PDF get?+

It depends on what's inside. Scanned or photo-heavy PDFs often shrink by more than half; PDFs that are mostly text or vector graphics are already small and change little.

Will it hurt the quality?+

Images are re-encoded and very large ones are scaled down to a sensible size — fine for email, screen, and normal printing. Text stays sharp because it isn't an image.

What if it can't be compressed?+

Then you get your original file back unchanged — we never hand back a bigger file.

Do you keep my file?+

No — files uploaded through the free tool are deleted automatically a few hours after the run.

Need this at scale?

Chain this into a full pipeline — extract, transform, route, deliver — and run hundreds at once.
