SysTools PDF Unlocker
What SysTools PDF Unlocker is
SysTools PDF Unlocker is a desktop utility for removing known user passwords and owner-permission restrictions from PDF files on Windows and macOS. It accepts individual files or folders for batch processing and supports 40-bit RC4, 128-bit RC4, 128-bit AES, and 256-bit AES encryption. User-password-protected files still require the correct password, and files without one supplied are skipped. The maker says the program works offline, keeping PDFs on the computer rather than uploading them. Unlocked documents can be saved or printed while preserving original formatting, and text editing is listed. The free version handles up to five PDFs and adds a SysTools watermark to saved files. The product does not remove certain DRM protections, and changing security settings may invalidate digital signatures. Paid licenses start at $39 a month.
