MicroPDF

The lightweight, 100% private PDF editor. Sign and edit offline.

MicroPDF is the secure, lightweight way to edit and sign PDFs directly in your browser. Stop uploading your sensitive contracts and tax forms to random servers. MicroPDF runs entirely on your device using WebAssembly, ensuring your documents never leave your computer. It is small, fast, and completely private. Key Features: ✍️ Sign Instantly: Draw smooth, natural signatures with the pen tool. 📝 Edit & Fill: Type text anywhere, add checkmarks, or fill out standard form fields. 🔒 100% Offline Privacy: No cloud processing. No sign-ups. No data collection. ⚡ Lightweight Power: Drag-and-drop fields across pages, group select items, and copy/paste with zero lag. 🎨 Professional Tools: Support for standard fonts (Helvetica, Times, Courier), custom colors, and precise resizing. How it works: Right-click any PDF link or file. Select "Open in MicroPDF". Edit, sign, and save instantly. Why use MicroPDF? Most PDF editors are "bloatware" or force you to upload private files to the cloud. MicroPDF is different. We stripped away the server dependencies to give you a tool that is microscopic in size but massive in utility.
