PDF Editor EN

PDF Editor turns any PDF into something you can mark up, sign, and share — entirely in your browser. No uploads, no accounts, no servers. Your files stay on your device.

═══ EVERYTHING YOU NEED TO MARK UP A PDF ═══

✎ Pen tool — freehand drawing in 7 pure colors with custom hex picker for any shade you want, plus adjustable stroke width
✎ Highlighter — true highlighter blending that preserves text crispness underneath, exactly like a real Sharpie on paper
✎ Text annotations — type directly on the page in Calibri, with full color, size, bold, italic, and corner-resize controls
✎ Numbered bubbles — drop sequential callouts for diagrams and engineering markup, with auto-incrementing numbers and 8 fill colors
✎ Signature pad — draw your signature once with mouse, trackpad, or touch, then place it anywhere; vector-based so it stays sharp at any size
✎ Stamps — 8 preset rubber stamps (APPROVED, DRAFT, CONFIDENTIAL, REVIEWED, REJECTED, PAID, URGENT, VOID) with optional date
✎ Image import — drop any PNG or JPG onto a page as a draggable, resizable annotation
✎ Find / Search — Ctrl+F to search text in the document, jump between matches with Enter / Shift+Enter
✎ Eraser — quick removal of any annotation
