Upload Your Signature to Sign PDF — Use Your Real Signature

What Uploading a Signature Image Does

Uploading a signature image lets you use a pre-created digital version of your handwritten signature on any PDF document. The image is embedded in the PDF at the location you specify. Using a PNG with a transparent background produces the cleanest result — the signature appears to float naturally on the document without a visible background rectangle.

Use cases include:

1. 1

   Professionals who sign documents frequently and want to reuse a consistent signature image.

2. 2

   Users who have a high-quality scan of their handwritten signature.

3. 3

   Anyone who wants their actual signature (not a drawn approximation) on digital documents.

4. 4

   Users who have created a signature in a drawing app and saved it as PNG.

5. 5

   Business users who need a consistent signature across many documents.

Your real signature, consistently applied to any document.

How it actually works

Technical explanation

What Signature Upload Provides

• PNG and JPG signature image support.
• Transparent background preservation.
• Drag-and-drop placement.
• Resize to fit signature lines.
• Consistent signature across documents.
• Secure processing with immediate deletion.
• Works on all devices.

When not to use this tool

• Using a JPEG signature image — the white background shows as a white rectangle on the document.
• Using a very small signature image — it may look pixelated when scaled up.
• Not removing the background from a scanned signature — the paper background shows on the document.

Best practices

• Create your signature image once with proper background removal and save it permanently. This investment pays off every time you sign a document.
• For a professional appearance, ensure the signature image has clean edges — no jagged pixels or visible background artifacts.
• Keep your signature PNG at a consistent size so it scales predictably when placed on different documents.

Alternatives

• Both methods produce a signature on the document — the difference is in consistency and convenience.
• Upload: consistent every time, uses your actual signature, requires one-time setup to create the PNG.
• Draw: natural and immediate, but varies slightly each time you draw.
