How can I generate a PDF and make it signable?

You can sign any PDF with airSlate SignNow. Once you import your PDF into airSlate SignNow and can see it on your Dashboard, you can easily edit the file, add fillable fields to it and even eSign it. If needed, you can also add signature fields for other signers (recipients), set signing orders for them, and send the document to them for signing right from your account. They’ll be able to sign right from their emails without creating an account of their own. Simply choose My Signature, click anywhere on the document, click Add New Signature, then type your signature, draw your signature, or upload your signature. Once that’s done, choose Sign and drag and drop the element wherever you want/need it. Follow that process for the rest, but use the Signature Field element instead.
