Is a drawn signature legally valid?
In most countries, an electronic signature is legally binding under laws like the ESIGN Act (US), eIDAS (EU), and equivalent legislation in Canada, Australia, and the UK — provided both parties agree to electronic signing.
For most everyday documents — lease agreements, freelance contracts, consent forms — a drawn signature on a PDF is fully valid. For high-stakes legal filings or notarized documents, check with your legal advisor.
Drawing vs. uploading a signature
| Method | Best for | Notes |
|---|---|---|
| Draw | Quick, informal signing | Mouse or trackpad; touch devices work well |
| Upload image | Consistent, professional look | Use a PNG with transparent background |
Does my signature get stored?
No. RizzPDF processes everything locally in your browser. Your signature and document are never sent to any server and are discarded when you close the tab. This is especially important for legal and financial documents.
Tips for a clean digital signature
- Use a stylus or finger on a touchscreen for the most natural-looking result
- If uploading an image, photograph your signature on white paper with good lighting
- Remove the background with a free tool before uploading for a clean embed
- Sign at a larger size then scale down — it looks cleaner than signing small
Can I add initials too?
Yes — you can place multiple signature instances on a document. Upload or draw your signature once, then click multiple locations to place it anywhere on the page.
