How It Works Under the Hood

How Electronic Signatures Work

When you sign a PDF electronically, we embed your signature as a visual element (image or vector graphic) directly into the PDF file structure.

The Process:

Signature Creation: Your drawn or typed signature is converted into a transparent PNG image.
PDF Modification: We open the PDF and add the signature image as a new layer on the specified page.
Positioning: The signature is placed at exact coordinates you specify by dragging it on the canvas.
Flattening: The signature becomes a permanent part of the PDF (not a separate annotation that can be removed).

Legal Validity: Electronic signatures are legally binding under the ESIGN Act (2000) in the US and eIDAS regulation in the EU for most business transactions.

How to Use Fill & Sign PDF in 3 Simple Steps

1. Upload Your PDF

Open Fill & Sign PDF and add your file. Processing stays on your device. If the PDF is password-protected, use Unlock PDF first.

2. Fill Form Fields or Stamp Text

If the PDF has fillable form fields, click a highlighted box (or use Tab) to type, check boxes, or pick dropdowns. Required fields show an amber hint until filled. For flat or scanned pages, switch to Stamp & sign to place text, checkmarks, initials, and dates.

3. Sign & Download

Open Sign to draw, type, or upload a signature. Click Download when ready. Optionally lock the result with Flatten PDF or Protect PDF.

Troubleshooting Common Issues

My signature looks pixelated or blurry.

If you uploaded an image, ensure it's high resolution (at least 300 DPI). For drawn signatures, draw larger and then resize down for crisper results.

I can't place the signature where I want.

Make sure you're dragging the signature image, not clicking. On mobile, use one finger to drag. You can also use the position controls to fine-tune placement.

The signature disappeared after I placed it.

This can happen if you accidentally clicked outside the canvas. Redraw or re-upload your signature and try again. Make sure to click "Apply" or "Download" to save it.

Can I sign a password-protected PDF?

You must unlock the PDF first. Use our Unlock PDF tool, then sign the unlocked file.

Common Mistakes to Avoid

✕ Using a low-quality signature image

Solution: If uploading a signature image, use a high-resolution scan (300 DPI) on white paper with a dark pen. Low-quality images look unprofessional and may be rejected.

Tip: For best results, draw your signature on white paper with a black pen, scan at high resolution, and crop tightly around the signature.

✕ Not checking signature placement before downloading

Solution: Always preview the signed document before downloading. Make sure the signature is on the correct line, properly sized, and not overlapping text.

Tip: Zoom in to check alignment. Most contracts have a specific signature line - make sure your signature sits on it, not above or below.

✕ Thinking electronic signatures are not legally binding

Solution: Electronic signatures are legally valid for most business transactions under ESIGN Act (US) and eIDAS (EU). They have the same legal weight as handwritten signatures.

Tip: For extra security, some organizations may require a digital certificate signature (PKI). Our tool creates standard electronic signatures suitable for most uses.

Can I sign PDFs on my phone?

Absolutely! Our tool works perfectly on iPhone, iPad, and Android devices. Draw your signature naturally with your finger on the touchscreen for authentic results.

Do I need to create an account?

No! Unlike DocuSign or Adobe Sign, you can sign documents instantly without creating an account, logging in, or providing your email address.

Can I add multiple signatures to one document?

Yes! You can add as many signatures as needed. Perfect for multi-page contracts that require initials on each page or documents with multiple signature lines.

How do I create a professional-looking signature?

You have three options: 1) Draw with your mouse or finger (most authentic), 2) Type your name and choose a handwriting font, or 3) Upload a high-quality image of your handwritten signature.

Will the signature be permanent?

Switch to Stamp & sign mode and place text, checkmarks, or a signature on the page—same as filling a flat or scanned PDF.
