How to Sign a PDF Online: Draw, Type, or Upload a Signature

Drawing works well when a mouse, finger, or stylus is available and you want a handwritten appearance. Typing is faster for repeatable signatures, while an uploaded signature is useful when you already have a clear scan or transparent PNG.

Whichever method you choose, place it deliberately in the correct signature block and include a date or supporting text field when the document requires it.

Check the signer name, page position, document version, and every visible field before downloading. A signature placed on an earlier draft can create avoidable confusion even when the mark itself looks correct.

Keep the unsigned source separately. The signed result should be treated as a final record, because later editing can change the document that the signature was intended to approve.

After signing, use password protection when the document contains confidential information. Send the password separately from the attachment, and make sure recipients know which final version they should retain.

NexaPDF AI requires a signed-in Premium account to apply signatures. Review the access requirement before preparing a time-sensitive document, rather than discovering it at the final step.
