Electronic vs digital signatures (quick clarity)
This tool adds an electronic signature (a visual signature placed on the PDF). A digital signature is certificate-based and cryptographic (often used in regulated workflows).
Best practice
If your organization requests a certificate-based digital signature, confirm the requirement first. For most everyday contracts and forms, an electronic signature is the expected workflow.
Privacy note
By default, signing runs locally in your browser. If any feature requires an upload, the UI should clearly indicate it. See Privacy Policy for details.
Troubleshooting
If something looks off after signing, these fixes solve most issues quickly.
My signature looks blurry
Use a higher-resolution signature image (PNG recommended), avoid tiny signatures, and export at normal zoom. If the PDF is a scan, consider running OCR first for cleaner appearance.
I need multiple signatures
Place as many signatures as needed across pages. If multiple people must sign, share the signed file and repeat the process for each signer if your workflow allows.
The portal rejects my signed PDF (file too large)
After signing, compress the PDF for upload limits. This is common with scanned PDFs and image-heavy documents.
Try Compress PDF after signing.
I need a certificate-based digital signature
This page adds an electronic signature (visual signature on the PDF). Certificate-based digital signatures are a different workflow and may be required by some organizations.
