About Sign PDF
Add a visible signature to a PDF without printing and scanning it. This is a signature placed on the page, not a certificate based digital signature.
Sign PDF runs locally without uploading your selected file or requiring an account. Although file selection allows up to 1 GB, available device memory can limit this particular task.
