Add a signature to a PDF in your browser
Use this tool when you already have a PDF and need to place a visible signature on one page. You can draw a signature, type your name in a signature-style font, or upload a signature image.
- Select a PDF. The document stays on your device and is read locally.
- Create or upload a signature. Choose Draw, Type, or Upload.
- Pick the page. The signature is placed in the lower-right area of that page.
- Download the result. The signed copy is created in your browser.
Electronic signature, not certificate signing
This page adds a visual electronic signature to the PDF page. It does not create a cryptographic digital signature, certificate signature, timestamp, or identity verification workflow. If your document requires legally regulated e-signature verification, use a certified signing platform.
Common uses
- Add a signature to forms, letters, invoices, approvals, and simple agreements.
- Use an uploaded transparent PNG signature for a clean result.
- Combine the result with Merge PDF or add page numbers with Add Page Numbers.
- Use Fill PDF Form first if the document has fillable fields.
Privacy and security
Your PDF and signature stay in your browser. PDF2atom does not upload, store, or inspect your document or signature image. Processing runs locally with pdf-lib.
Frequently asked questions
Is my signature uploaded?
No. The PDF and signature are handled locally in your browser. PDF2atom does not receive the file or signature image.
Is this the same as Sign PDF?
It uses the same browser-based signing engine. This page focuses on the common search intent of adding a signature image or typed signature to an existing PDF.
Can I add a certificate-based digital signature?
No. This tool adds a visual electronic signature only. It does not create a cryptographic certificate signature.
Can I choose the exact signature position?
You can choose the page. The signature is placed in the lower-right area, which works for many forms and letters.
What file type should my signature image use?
PNG with a transparent background gives the cleanest result. JPG also works but may include a white background.
