How to sign a PDF form electronically from my phone?

I need to sign a PDF form on my phone before sending it back, but I’m not sure how to add a signature that stays in the document. What should I be looking for?

I ran into this with a contract on my phone. Open it in a PDF app with a “Fill & Sign” or “Add signature” option, draw or type your signature, then save a new copy before sending it back. Reopen the saved file to make sure the signature is still there.

If you have an iPhone, the Files app lets you open the PDF and there’s a markup tool (looks like a pen tip) where you can draw your signature with your finger. Android phones usually have something similar built into Google Drive’s PDF viewer. What phone do you have?

If you are on an iPhone, open the PDF in the Files app, tap the marker icon, hit the plus sign, and pick Signature. It saves directly to the document.

On Android, open it through Google Drive and tap the pen icon in the corner to draw and save your signature.

First thing I’d check is whether your phone’s built-in Files app or mail preview has a markup or draw option. Open the form there, add your signature with your finger, then save or export a copy rather than just closing it. Keep a backup of the original first, and reopen the saved file to make sure the signature stayed put.

I use PDFcap for this kind of thing on my phone. Open the form, draw your signature with a finger, and save it so it stays in the document.
Avoid just dropping in a photo of your name because those can get moved or lost. Not sure if it’s the same on Android.

Start by checking whether the form has a built-in signature field. On my phone, I use the markup or fill-and-sign option in the viewer, draw my signature with a finger, then save a new copy before attaching it to email.

Open the saved copy once to make sure the signature is still visible. For anything contractual, I also keep the unsigned original separately.

Had the same thing with a tax form last month. Look for a “Fill & Sign” or “Markup” tool in your PDF app, then create your signature and place it in the signature box. Save a new copy and reopen it before sending to make sure the signature stayed put. If the form requires a certificate-based digital signature, a basic drawn signature may not be accepted.

if you’re on iphone, open the pdf in files or mail, tap the markup pen icon, then the plus sign and add signature. draw it once and it saves for reuse. on android i usually point people to adobe fill and sign, free and does the same thing.

@distracted_hunter That approach usually works well. I had to sign a grant application recently and just used my phone’s default mail app to scribble it. My old laptop struggles to load large forms, so the phone is often faster anyway. You are right about avoiding inserted photos since they often disappear in submission portals.

@orla_ward honestly the default mail app is a total lifesaver. i sign supplier invoices the exact same way when i’m short on time. just open the attachment, scribble your name on it and send it right back.
