A complete PDF editor that never leaves your browser

PDF Editor Pro is a full-featured editing workstation for PDF files — built to run entirely on the client side. There's no upload step, no waiting for a server to process your document, and no account required. Open a file, edit it, and download the result, all without your document ever touching a server.

What you can do

• Annotate & draw — add text boxes, highlights, underlines, strikeouts, sticky notes, callouts and freehand drawing.
• Sign documents — draw, type or upload a signature and place it anywhere on the page.
• Organize pages — reorder, rotate, duplicate, delete or insert blank pages.
• Add watermarks & stamps — text or image watermarks with custom opacity, rotation and page range.
• Headers, footers & page numbers — with placeholders for page count, date and filename.
• Redact sensitive content and flatten the document before sharing.
• Run OCR on scanned pages to pull out searchable text.
• Batch process multiple PDFs with the same operation in one pass.

Why it's private by design

Every operation — rendering, editing and saving — happens using PDF.js, PDF-lib and Fabric.js running directly in your browser tab. Your file is read into memory locally and the edited copy is generated the same way, so nothing is ever transmitted anywhere.
