PDF Ready

Visible handwritten signature

Add a handwritten signature to a PDF on Android

PDF Ready can add a visible handwritten signature to compatible PDFs on Android. It is a visual mark placed on the document, not a certified e-signature.

What this feature is

  • Draw or capture one handwritten signature asset for the document.
  • Place it visually on a compatible PDF page.
  • Reuse the same signature on pages of the same document when needed.

What this feature is not

  • It is not a certified e-signature.
  • It is not a remote signing workflow or multi-signer system.
  • It is not a full annotation suite or arbitrary layer editor.

Where it fits in the workflow

  • Add the visible signature in Originals before Prepare.
  • Review placement and readability.
  • Then choose the upload target and prepare the clean export.

When to be careful

  • Do not modify signed or validated PDFs when the existing signature or validation matters.
  • Only add a visible signature when the destination accepts that kind of mark.
  • Keep the original file untouched until the destination accepts the submitted copy.

FAQ

Common questions

Is this a certified e-signature?

No. It is a visible handwritten mark, not a cryptographic or certified signing method.

Can I place the same signature on multiple pages?

PDF Ready is designed around one signature asset that can be reused on pages of the same document where supported.

Do I pay to add the signature?

No. The paid step is the final clean export, not capturing or placing the visible signature.
