A complete free online PDF editor that works entirely in your browser. Add or replace text, insert images and signatures, highlight, redact, draw shapes, and rearrange pages — all without uploading your file to any server. No signup, no watermark, no file size limit, no page count cap.
Whether you need to fix a typo in a contract, sign a document, fill out a form, or merge edits from multiple sources, this editor handles it. Your PDF stays on your device the entire time — true privacy by design.
Most online PDF editors upload your file to their servers, process it there, and send it back. That's a privacy problem when your document contains contracts, medical info, financial statements, or anything sensitive — you're trusting an unknown server with confidential data.
This editor is different. Everything happens locally in JavaScript using pdf-lib for writing and PDF.js for rendering. Once the page loads, you can disconnect from the internet entirely and the editor still works. Your file never leaves your device.
This editor handles general editing. For specialized tasks, use a dedicated tool — they're all free and browser-based:
