Sign quickly on mobile
Draw with a finger or stylus and use position presets when precise dragging is inconvenient.
EXPERT POST
Practical rules for adding a signature to a PDF
Visible signatures vs certificate signatures, transparency, page rotation, placement, repeated pages, and local privacy handling.A visible signature is not a certificate signature
This tool adds a visible signature graphic. It does not provide PKI certificate validation, timestamps, identity verification, or a guarantee of legal validity.
The PDF page is not rasterized
The original PDF page objects are kept where possible and only the signature image is overlaid, instead of converting every page to a bitmap.
Transparent PNG keeps the document readable
Signature images are normalized to PNG in the browser. Existing transparency is preserved; a white JPG background is not automatically removed.
Aspect ratio stays locked
Changing signature width recalculates height from the original aspect ratio instead of stretching the signature.
Mixed page sizes and rotation need coordinate conversion
Relative preview coordinates are converted for each page size and rotation so placement remains visually consistent.
Apply only the pages you need
Choose current, all, odd, even, or a custom range such as 1-3,5. Duplicate page numbers are applied only once.
Sensitive files stay local
The PDF, signature image, and drawing data are not intended for server storage; the result is generated in the browser.

FAQ
FAQ
01Is this a certificate-based digital signature?+
No. It visually places a drawn or image signature on PDF pages and does not validate a PKI certificate.
02Are my PDF and signature uploaded?+
No. They are designed to be processed in the current browser rather than stored on a server.
03Can I put the signature in the same place on multiple pages?+
Yes. Apply it to all, odd, even, or a custom page range using the same relative placement.
04Can I use a transparent PNG?+
Yes. Existing PNG alpha is preserved when the image is normalized and embedded.
05What if page sizes are different?+
Placement is converted from relative coordinates for each page size and rotation.
