Frequently asked questions

Why compress a PDF before sharing it?

A smaller file is easier to email, faster to upload, and less likely to hit attachment size limits.

Will compressing a PDF always make it dramatically smaller?

Results depend on the original file. Documents with large images usually benefit more than text-heavy PDFs.

Are my files uploaded to a server?

No. This tool is designed to process files inside your browser so you can work on sensitive PDFs without waiting for an upload queue.
