About Compress PDF

Compress PDF reduces your PDF file size by re-optimizing the internal structure, removing unused objects, and rebuilding cross-references. This is ideal for PDFs that need to be emailed (most providers limit attachments to 25MB), uploaded to web portals, or stored efficiently. The compression happens entirely in your browser, so your confidential documents are never sent to external servers.
