What does Compress PDF do?
It reduces a PDF's file size by re-encoding its page images at an adjustable quality level.
Will this reduce text quality?
Compression targets embedded images on each page; it won't blur selectable text, though very image-heavy PDFs will shrink the most.
Where is my file processed?
Entirely in your browser — the PDF is never uploaded to a server.
