Is there a file size limit?

Since all processing is done locally in your browser using PDFLib, the practical limit depends on your device's memory. Most PDFs up to 50MB work well on modern computers. There are no artificial server-side limits.

Can I password-protect my PDF?

Yes, you can add password protection to your PDF files. Set a password and only people with the password will be able to open and view the protected PDF. The encryption is applied in your browser.

What operations are supported?

PDFForge supports merging multiple PDFs, splitting pages, compressing file size, protecting with password, extracting specific pages, and converting images to PDF. Each operation is available as a separate tab.

🔒 100% Private & Secure

PDFForge uses PDFLib v1.17.1 and PDF.js v3.11.174 — both SRI-verified via cdnjs. The PDF.js Web Worker is self-hosted (SRI-verified, served from the same origin). Your files are never sent over the network — verify in your browser's Network tab. We use strict CSP headers with 'unsafe-eval' (required by PDFLib) and SRI for all dependencies.
