About the Compress PDF to 500KB tool
Uploading certificates, ID scans or signed forms often comes with a 500 KB limit, while phone scans are usually several megabytes. This tool rebuilds each page at the best quality that still meets the limit. For documents with many pages, consider splitting the PDF first and uploading only the pages that are required.

Frequently asked questions
Will the text still be readable?
For most scans and certificates of a few pages, yes. If you have many pages, remove the ones you don't need with Split PDF first — fewer pages means better quality per page.
Can I select text in the compressed PDF?
No. Pages are saved as images to reach small sizes, so the text becomes part of the picture.
Is 500 KB the same as 0.5 MB?
Almost — 0.5 MB is 512 KB. If a form says 0.5 MB, a file under 500 KB is always safe.
Is it free?
Yes, completely free with no limits or watermarks.
