Frequently asked questions
How do I compress a PDF to 500 KB?
Drop your PDF in the box above and click “Compress PDF”. The target is set to 500 KB, so the result will be 500 KB or smaller whenever possible.
Will the PDF still be readable?
Yes for most documents. Very long PDFs squeezed into a small size lose sharpness, so split them if needed.
Is my document uploaded?
No. Compression runs entirely in your browser.
