Frequently Asked Questions

How do I reduce a PDF to 300 KB?

Upload your file and click Compress to 300 KB. We try the least harmful method first and go further only if needed.

Why is the result a little under 300 KB?

We aim slightly below the limit because some upload forms count size differently, and a file just over the limit gets rejected.

What if my file is already under 300 KB?

We tell you it is already small enough and let you download it unchanged.

Is the text still selectable?

Usually yes. If the size cannot be reached with text, we rebuild pages as images and tell you. You can also tick Keep text selectable.

Is it free to use?

Yes. This tool is free, has no daily limit and does not ask you to sign up or install anything.

Are my files uploaded to a server?

No. The work is done inside your own browser, so your file stays on your device. We never see or store your documents.
