PDF Editor
Annotate, draw, highlight, add text and images to a PDF — then flatten to a new file. Rich editor, 100% in your browser.
Overview
PDF Editor is a rich, browser-based markup tool for PDFs. Open a document and work through it page by page in a zoomable viewer, adding text anywhere, drawing freehand, highlighting passages, and placing images, stamps, or signatures. Everything you add can be moved, deleted, or undone. When you save, your annotations are flattened onto the pages as vector text, shapes, and images — the original content, including selectable text, is preserved underneath, not turned into a screenshot. The whole editor runs client-side with pdf.js and pdf-lib, so your file never leaves your device.
