About PDF Compressor

Optimize PDF files to reduce file size for email attachments and portal uploads. Re-encodes object streams and strips unused metadata directly within your browser.

Unlike traditional web tools that send your personal data, uploaded photos, or sensitive text to remote cloud servers, our PDF Compressor operates strictly inside your client browser sandbox. This guarantees high processing speeds without network throttling, and ensures your data privacy is completely preserved.
