Protect PDF
Password-protect your PDF to restrict access.

Every PDF tool on ConvertForge runs in your browser using pdf-lib and pdf.js. Your documents are processed locally — they never leave your device. Free to use, no signup required, and no watermark added to your output files.
ConvertForge uses pdf-lib for PDF editing and creation, and pdf.js for rendering — both libraries run entirely in your browser. Your PDF files are never uploaded to any server. All splitting, merging, compressing, and page manipulation happens locally on your device. This makes ConvertForge appropriate for confidential documents — though you should always follow your organisation's data policies when handling sensitive files.
