Frequently asked questions

• How much can I compress a PDF?+
  Compression depends on the content. PDFs with large images typically compress 40-70%. Text-heavy PDFs compress less. The tool shows you the size before and after.
• Will compressing reduce text quality?+
  No. Text in PDFs is vector-based and is not affected by compression. Only embedded images are re-encoded at a lower quality setting.
• What does the Cleanup PDF tool fix?+
  It auto-rotates sideways pages, removes blank pages, normalizes mixed orientations, and re-encodes images at optimal quality. A cleanup report shows exactly what was fixed.
• How strong is the PDF password protection?+
  The Protect PDF tool uses RC4-128 bit encryption — the standard for PDF password protection. It prevents the file from being opened without the password.
• Can I remove the password from a protected PDF?+
  The Protect PDF tool adds passwords. To remove a password you already know, open the PDF in your browser (Chrome, Firefox) with the password and re-save it.
• Is my PDF safe when I compress or protect it?+
  Yes. All processing happens in your browser. Your PDF never leaves your device — not even for password protection, which is done using local JavaScript encryption.
