Sign PDF
Add a visual signature to a PDF page by uploading an image, drawing, or typing your signature.
Why use Sign PDF?
Practical advantages built around real creation, selling, and operations workflows.
Three signature inputs
Upload a PNG or JPG signature image, draw on a canvas, or type a signature that is converted into a visual stamp.
Page-specific placement
Choose the page that should receive the signature and place it with practical presets or custom point coordinates.
Adjustable appearance
Control signature size and opacity before creating the final stamped PDF.
Preserves PDF content
The server embeds the signature over the selected page while keeping the existing PDF content intact.
Standard PDF Studio workflow
Successful outputs use shared tool engine credits, R2 output storage, signed-in history, analytics, and feedback widgets.
Three simple steps
Launch the workflow from this page and keep moving without extra setup.

Sign PDF questions
Answers to common questions before you run the tool.
How many credits does Sign PDF use?
Sign PDF uses 2 credits per successful signed PDF.
Is this a digital or cryptographic signature?
No. Sign PDF adds a visual signature stamp to the page. It does not create a cryptographic digital signature or make legal validity claims.
Which files can I upload?
The tool accepts one readable, unencrypted PDF file up to 50MB with MIME type application/pdf.
Which signature images are supported?
You can upload or generate a PNG or JPG signature image up to 5MB.
Can I choose the signature page and position?
Yes. Choose the target page, a placement preset such as bottom-left, bottom-center, or bottom-right, or custom coordinates.
Are source PDFs stored permanently?
No. Source PDFs are parsed from the upload request for temporary processing only; only the signed output is stored for download and history after success.
