How it works
Upload any PDF document and the editor automatically analyzes page dimensions, text coordinates, font metrics, and reading order.
When you edit text, original bounding boxes are erased cleanly and replacement text is drawn with matching font properties and automatic size fitting.
Signatures and layout preservation
Create custom signatures by drawing, uploading an image, or typing with cursive script fonts. Position, scale, and rotate signatures anywhere on the document.
Your original page dimensions, background elements, and surrounding text remain completely unchanged.
Frequently Asked Questions
Are my images uploaded to a server?
No. Every conversion runs locally in your browser using your device's own processor. Your images never leave your computer or phone, and nothing is stored on our servers.
Does it preserve the original PDF layout?
Yes. The editor detects original font metrics and bounding boxes, replacing content cleanly without shifting surrounding text or damaging page structure.
Can I add and draw signatures?
Yes. You can draw signatures using mouse or touch, upload a PNG/JPG signature image, or type your name in cursive script fonts.
Is it free, and are there limits?
It's completely free with no account required. Because processing happens on your device, there's no per-file upload limit — the practical ceiling is your device's available memory. You can batch many files and download them as a single ZIP.
