Compressing turns each page into an image, so the text can no longer be selected or searched. Keep your original file too. Your files never leave your device. Everything happens inside your browser, even offline after the page loads.

Frequently asked questions

How does it hit an exact size?

It tries different image qualities and page sharpness, and keeps the best-looking version that still fits under your size.

Will my text still be selectable?

No. To get very small sizes, each page becomes an image. That is fine for forms and uploads, but keep the original for editing.

Is it free?

Yes. The Compress PDF (to an Exact Size) on Assignment Lab is completely free with no sign-up, and it works right in your browser. Nothing you type or add is uploaded.
