About this tool
Sign PDF adds a visible signature image to one or more pages of a document. Create the mark by drawing with a mouse, finger, or pen, typing a name in a handwriting-style font, or uploading a PNG, JPG, or WebP image. The transparent result can be dragged, resized proportionally, and placed several times.
The page viewer handles ordinary, rotated, and cropped PDF pages while keeping each signature upright where it was positioned. An optional locale-formatted date appears beneath every stored placement. This tool creates a visual signature for appearance and acknowledgement; it does not issue or validate a certificate-based cryptographic digital signature.

Features
Three signature sources
Draw smooth pointer strokes, render typed handwriting-style text, or preserve transparency from an uploaded signature image.
Multi-page placement
Add separate signature placements to several pages while navigating with previous and next page controls.
Precise accessible movement
Drag and resize with pointer controls, or use arrow keys for movement and Shift with arrows for proportional resizing.
Optional local date
Print today's date beneath each signature using the date format supplied by the current browser locale.
Rotation-aware drawing
Map visible page coordinates through crop offsets and stored page rotations so placed artwork remains upright.
Frequently asked questions
Is this a certificate-based digital signature?
No. The output contains a visible signature image, similar to placing an ink mark on a printed page. It does not add a signing certificate, cryptographic identity proof, tamper validation, or a trusted timestamp.
Can the same signature appear on several pages?
Yes. Navigate to each required page, adjust the box if needed, and select Add to this page. The placements list lets you remove an individual page entry before signing.
How does the drawing pad work on touch screens?
The pad uses pointer events and disables browser touch gestures within its surface, allowing mouse, touch, and compatible pen input to produce continuous rounded strokes.
What happens to transparent signature images?
PNG and WebP transparency is retained when the browser decodes the upload. Empty borders are trimmed to the visible ink bounds before the mark is placed in the PDF.
Are signed documents uploaded anywhere?
No. PDF reading, signature creation, page rendering, placement, and final file generation all take place in the active browser tab.
