How to compress a PDF to 500 KB

Why compress without uploading

Every upload to a compression site is a copy of your document on a server you do not control. Doing it in the browser avoids that copy entirely.

Frequently asked questions

Will 500 KB keep my scan readable?+

Usually yes. 500 KB is generous enough for most scanned documents to stay clear, unlike very tight caps like 100 KB.

Is my document uploaded?+

No. Compression happens in your browser and the file never leaves your device.

Can I compress several files?+

Yes, you can compress files one after another; each is processed locally.

Is it free?+

Yes, with no sign-up.
