Specifications and notes

Input	One PDF and a drawn, typed, or uploaded signature image
Placement	A signature image can be positioned and resized on the selected page
Signature type	Visual signature mark; not a certificate-based cryptographic digital signature

Privacy and processing

The PDF and signature image are processed in the browser and exported locally. This adds a visual mark; it does not apply a cryptographic certificate or verify a signer's identity.

Frequently asked questions

Is this a legally verified digital signature?

The tool places a visual signature mark in the PDF; it does not create or validate a certificate-based cryptographic signature. Check the recipient's requirements for an accepted signing method.

Can I move or resize the signature?

Yes. Position and resize the signature image in the page preview before downloading.

Does it alter every page?

No. The signature is added to the selected page. Navigate to the intended page before exporting.

Adding a signature mark to a PDF

A signature tool can place a drawn or typed mark on a document. A visual mark is not necessarily a cryptographic digital signature and may not meet the legal or recipient-specific requirements for execution.

Recommended workflow

Confirm you have authority to sign the document, review the complete text first, and place the mark only in the intended location. Save an unmodified original and follow the recipient's instructions for identity verification, witnesses, certificates, or other formalities.

Review before using or sharing

Open the output and check the signature position and all pages. Ask the recipient whether a visual signature is acceptable; some workflows require a specific e-sign service or certificate. Never sign on behalf of another person without lawful authorization.

Privacy and responsible use

Treat signed files as sensitive. Check the tool notice for its processing path and keep exported documents secure. Account and document-storage features elsewhere in DigiCyberCafe use server-side services described in the Privacy Policy.

A careful final check

Before you begin, identify the exact outcome you need and the rules of the service that will receive it. A file-size limit, image dimension, page order, or calculation date can be more important than a default setting. Keep source material unchanged, use only the minimum personal information required, and do not enter credentials or payment secrets into a general utility. If the browser reports an unsupported file or an incomplete result, stop and verify the source rather than assuming the export is correct.

After processing, compare the output with the source and test it in the context where it will be used. Check the receiving organization's current instructions, confirm that the format and file size are accepted, and retain a secure copy of important originals. For official, financial, legal, or identity documents, ask the responsible authority or a qualified professional when a decision depends on interpretation. These practical checks help catch common errors, but they do not replace an official review or guarantee that a result will be accepted.

Keep a clear distinction between a file saved only on your device and a file deliberately sent to an outside service. Some browser tools load fonts or models from third parties, and translation sends selected text to its provider after you give consent. Review prompts before confirming, close the page when finished on a shared computer, and delete temporary downloads or local browser data when appropriate. If a tool uses a server-backed feature, its processing route should be checked in the Privacy Policy before submitting sensitive material.

Frequently asked questions

Is a drawn mark a verified digital signature?

No. A visible mark alone does not establish identity, document integrity, or certificate-based signature validity.

Is this legally valid everywhere?

Legal effect depends on jurisdiction, document type, identity checks, consent, and recipient rules. Obtain appropriate advice when needed.
