Compress PDF questions
It depends on what is inside. Files with lots of photos or scans often shrink by half or more. Files that are mostly text are already small and may not shrink at all. If we can't make a file smaller, you get your original back.
No. Text and vector drawings are left exactly as they are, so they stay sharp and selectable. Only images are re-saved, at the level you choose.
Recommended suits most documents. Choose Light for print or photos where detail matters, and Strong for email attachments and upload limits.
Yes. Compression runs in your browser, so your PDF is never uploaded to our servers.
