About PDF Editor
Need to quickly edit a PDF without installing expensive software? ToolForge AI's PDF Editor lets you modify PDF documents directly in your browser — no uploads, no accounts, no desktop apps.
Full editing capabilities
Add and edit text anywhere on the page with your choice of 20+ fonts, any size from 8px to 72px, in any color. Apply bold, italic, and underline formatting just like a word processor.
Annotate and draw
Use the pen tool to draw freehand annotations, or the highlighter to mark important sections. Add shapes like rectangles, circles, and arrows to call attention to specific areas.
Multi-page support
Navigate between pages seamlessly. Each page retains its own annotations and edits. When you export, all pages are compiled into a single edited PDF.
100% browser-based privacy
Your PDF never leaves your device. All editing happens locally using PDF.js for rendering and Fabric.js for the interactive canvas. The exported PDF is generated using pdf-lib — entirely client-side.
