Frequently asked questions

Can I compress more than one PDF at a time?

No. This version of Compress PDF handles one file per run.

Files are sent to DooPDF's compression service, processed there, and then returned to your browser for download.

Will the file always become smaller?

Not always. Compression is most effective for image-heavy PDFs.
