Why it matters
Start with the most common and cheapest causes to narrow it down fast.
Check the signature field type.
Step by step
- Confirm the document accepts an image/e-signature.
- Draw on a blank canvas and keep it consistent with your normal handwriting.
- Export a high-resolution transparent or white PNG.
- Place it in the PDF/Word file and check position/size/sharpness.
- Use compliant e-signature/notarization for important contracts; don't just paste an image.
Common mistakes
- Pasting an image on an important contract and assuming it is legally signed.
- Exporting too low a resolution, so it prints blurry.
- Transparent PNG with a white/gray halo.
- Sharing the signature image freely, enabling misuse.
Checklist
- The document/platform accepts an image signature.
- The signature matches your normal handwriting.
- PNG resolution/background are correct.
- Placement/size look right after insertion.
- Important documents use compliant e-signature/notarization.
Key facts
- Check the signature field type.
- Save the confirmation page after submission.
