PRODUCT SPECIFICATION

Understand Sign PDF with a Visible Label before you process a file.

A visible label can support drafts, informal approvals, or printed workflows where cryptographic proof is not required.

Important boundary

This operation has no certificate, private key, timestamp authority, identity verification, or tamper detection.

THREE-STEP WORKFLOW

From source PDF to checked result.

The label is positioned relative to the selected page's current visible CropBox.

1. Upload and validate

Choose an unlocked PDF that you are authorized to mark and confirm its physical page count.

2. Set the operation

Enter the display name, select one page, and choose a corner that does not obscure source content.

3. Download and review

Inspect the label and share it only when a visible acknowledgement meets the workflow requirement.

KNOW BEFORE YOU USE IT

This is not a digital signature.

The output contains visible text only. It does not verify identity, prove consent, lock document contents, detect changes, or meet certificate-based electronic-signature requirements.

COMMON QUESTIONS

Details that affect the result.

Is this legally equivalent to a digital signature?

No. Legal and organizational requirements vary, and this tool creates only a visual label without cryptographic evidence.

Can I upload a handwritten signature image?

Not in this version. The tool adds a text label with the signer name.

Can I label multiple pages?

One request labels one selected page. Run separate authorized copies if your workflow truly requires multiple labels.

Nirmion Sign PDF places a boxed Signed by text layer on one selected page with a configurable corner position and validated signer name.

The product clearly distinguishes visual stamping from cryptographic digital signatures. Use a certificate-backed signing service when identity, integrity, and non-repudiation matter.
