Sign PDF Online
Add a signature to a PDF in your browser with no upload
Original PDF is not changed. This adds a visible signature image, not a certificate-based digital signature.
About this tool
Sign PDF Online is a free PDF signing tool that adds a visual signature to a PDF in your browser — neither the document nor the signature is uploaded. Draw with adjustable pen color and size, type a signature with font preview, or upload a PNG, JPG, WebP, HEIC or HEIF image, then place, drag and resize signatures on a single page, every page or a page range. This is a visual signature, not a certificate-based digital signature.
How to use
- Add a PDF. Drop a PDF into the upload area or click to choose a file from your device.
- Create a signature. Draw a signature with pen color and size options, type a signature with a font preview, or upload a PNG, JPG, WebP, HEIC or HEIF signature image.
- Place signatures. Select a page and add the signature to the current page, every page, or a page range. Drag, resize or delete each placement independently.
- Download the signed PDF. Apply signatures to create a new PDF copy, then download the result when it is ready.
FAQ
Are my PDF or signature uploaded?
No. The PDF preview, signature creation and final PDF export run in your browser. Files do not leave your device.
Is this a certificate-based digital signature?
No. This tool adds a visual signature image to the PDF. It does not create a certificate-backed digital signature or verification workflow.
Can I sign a PDF on mobile?
Yes. You can draw with your finger, type a signature, upload a signature image and place it on PDF pages from a mobile browser.
Can I sign multiple pages?
Yes. Add the same signature to the current page, all pages, or a page range. Each placed signature can be moved or resized separately.
Can I upload a signature image?
Yes. You can upload a PNG, JPG, WebP, HEIC or HEIF signature image and place it on the PDF like a drawn signature.
How do I sign a PDF without Adobe Acrobat?
