1. Going Paperless: Sign Contracts Without Print & Scan Cycles

Printing multi-page agreements, manually signing with a pen, and re-scanning them is an outdated, costly ritual. Signing PDFs on mobile allows you to finalize deals on the go.

2. Drawing Fluid Signatures with Touchscreen Smoothing

Tap 'E-Sign' inside Offline PDF Editor to access a digital canvas equipped with curve smoothing algorithms. Your stroke lines look natural, just like premium fountain pen ink.

  • Select classic ink colors: Jet Black, Royal Blue, or Navy.
  • Auto-transparent background prevents covering document text.
  • Save signature templates for rapid signing across multiple pages.

3. Adding Dates and Typed Names

Use the annotation module to type your full name and timestamp next to your signature. Flatten the document to lock elements permanently into place.

Frequently Asked Questions (FAQ)

Q: Can other people extract my signature from the PDF?

The signature is flattened into the page rendering layer and files are processed strictly offline, keeping your biometric marks private.

Q: Can I import an existing signature image from paper?

Yes. Import a photo from your gallery and the app will isolate the stroke while stripping the white background.

Q: Can I sign multiple pages quickly?

Yes, use saved presets to place your signature or initials across pages with a single tap.
