Processed locally — never uploaded

Your PDF is read and transformed in this browser tab using WebAssembly/JavaScript (pdf-lib). Files are not sent to Toolminator servers. Close the tab to clear memory; download only when you choose. How file processing works

Best for email attachments: compress first, then check file size. Scanned PDFs shrink less than text-native files. PDF compress guide

Common mistakes

  • Processing confidential contracts or ID scans on a shared or public computer—use a trusted device.
  • Assuming local processing means zero risk: malware, extensions, or screen capture can still expose files.
  • Expecting pixel-perfect PDF layout after heavy compression—always open the output before sending.
  • Uploading the same export to multiple untrusted third-party converters after using a local tool.

FAQ

Is my data uploaded?

No. Processing happens locally in your browser unless the tool explicitly states otherwise.

Can I use this on mobile?
