Why might the file not get smaller?

This browser-only compressor helps most with scanned or image-heavy PDFs. Text-only PDFs may already be compact.

Does compression change quality?

Yes. Pages are rebuilt as JPEG images, so choose a higher quality setting for documents you need to print.

No. Rendering and rebuilding happen in your browser.
