Sign PDF — Complete Guide & Instructions
MakeCard Sign PDF lets you sign a PDF without printing or uploading anything. Load the file, draw your signature on the pad, then click on the rendered page wherever the signature should appear — across as many pages and positions as needed. The finished document is reassembled locally with pdf-lib and downloads as signed.pdf. Perfect for contracts, consent forms, and application documents.
How to Use Sign PDF
- 1 Drag a PDF onto the dropzone or click "Choose PDF".
- 2 Draw your signature in the left-hand pad; adjust the pen slider and hit Clear to redo.
- 3 Navigate pages with the ‹ › arrows and click on the page preview to stamp the signature at that spot.
- 4 Repeat on any other pages; the counter shows how many signatures are placed, and Undo removes the last one.
- 5 Click "Download Signed PDF" to save the finished file.
Key Features & Capabilities
- Place signatures on any page by clicking exactly where they should appear.

- Signature pad with adjustable pen width and a one-click Clear.
- Accurate page preview rendered by PDF.js with your stamps shown in place.
- Undo button removes the last placed signature.

Practical Everyday Use Cases
- Signing a rental agreement or contract received by email.
- Adding initials or a signature to every page of an application form.
- Signing consent and declaration forms for school or HR.
- Countersigning a scanned document without a printer.
- Approving an invoice or quotation PDF before returning it.
Pro Tips for Best Results
- Draw the signature once — you can stamp it on unlimited pages from the same pad.
- Click near the signature line, not on it — the stamp centers on your click point.
- Zoom mentally using the page navigation — check each page after stamping to confirm position.
- Keep the original unsigned PDF; the tool downloads a new signed.pdf and never modifies the source file.
Common Problems & Solutions
You clicked the page before inking the pad — draw on the left canvas, then click the page to place it.
Press Undo to remove the last stamp and click again — each stamp centers on your click point.
Remove the password with your PDF viewer first; the tool can open many lightly encrypted files but not fully locked ones.
Privacy & Security
100% Client-Side Execution
The PDF and your signature are processed entirely in your browser — nothing is uploaded to a server at any step.
