What is a PDF Signing Tool?

A PDF signing tool is a software or online service that allows you to add your signature (handwritten, drawn, or an image) to a PDF document. Unlike digital certificates that use cryptographic keys, a signing tool like Web tool Bazar’s simply places a visual representation of your signature onto the file. This is perfect for contracts, agreements, consent forms, and any document that requires a personal touch.

Why Use Web tool Bazar’s PDF Signing Tool?

  • 100% Private: Your PDF and signature never leave your device – no server uploads.
  • Live Preview: See exactly where your signature will appear before you finalize.
  • Multiple Signature Options: Draw with your mouse/touch, or upload an image of your wet signature.
  • Free & Unlimited: No registration, no watermarks, no hidden costs.
  • Works Offline: After the first load, you can disconnect from the internet and still sign.

How to Use the PDF Signing Tool (Step‑by‑Step Guide)

Follow these simple steps to sign any PDF in minutes:

  1. Step 1: Upload your PDF – Drag and drop your PDF file onto the designated area or click “Select PDF”. The tool will read the first page and display its dimensions.
  2. Step 2: Create your signature
    • Draw: Use the “Draw” tab. Sign inside the canvas with your mouse or finger (on touchscreens). Click “Use Drawing” to save it.
    • Upload: Use the “Upload Image” tab. Select a PNG, JPG, or GIF of your signature. Click “Use this image”.
  3. Step 3: Position your signature – After the signature is loaded, you’ll see a red dashed rectangle on the preview. Use the X (left), Y (bottom), and Scale sliders to move and resize the signature. The preview updates instantly.
  4. Step 4: Sign the PDF – Once you’re happy with the placement, click the “Sign PDF” button. The tool embeds the signature onto the first page.
  5. Step 5: Download – Click “Download Signed PDF” to save your document. The original file remains unchanged.

Pro Tips for Best Results

  • For a clean signature, use a white background and black ink when uploading an image.
  • If you’re drawing, try to use a stylus or your finger on a touchscreen for more natural strokes.
  • The Y coordinate is measured from the bottom of the page – typical for PDF coordinates.
  • If your PDF has multiple pages, the signature is placed only on the first page. For multi‑page signing, repeat the process for each page or use a desktop tool.

Frequently Asked Questions (FAQ)

Is a signature added with this tool legally binding?

In many jurisdictions, a scanned or image‑based signature is considered valid if it can be proven that the signer intended to sign. However, for highly sensitive legal documents, a certified digital signature (with a digital certificate) may be required. Consult a legal professional for your specific case.

Can I sign a PDF on my phone?

Absolutely. The tool is fully responsive and works on smartphones and tablets. You can draw with your finger on the canvas.

What image formats are supported for signature upload?

You can upload PNG, JPG, GIF, and WebP. We recommend PNG with transparency for a clean overlay.

Will my signature be editable after I download?

The signature becomes part of the PDF content (like an image). It can be removed or altered only with advanced PDF editing software, but it is not cryptographically tamper‑proof.

Can I sign a password‑protected PDF?

No, you must remove the password first. Use our PDF Locker tool to unlock (if you know the password) before signing.

Is there a limit on file size?

Yes, 50MB – which covers most PDFs. If your file is larger, consider compressing it first with our Compress PDF tool.
