My landlord just emailed me a PDF lease renewal that needs my signature before tonight, and I am stuck away from my laptop with only my Android phone. I tried opening the attachment from my email, but it only lets me view the pages and I cannot figure out how to draw my name on it. Is there an easy way to sign a PDF directly on a phone and send it back without needing a computer? ---

Honestly the quickest fix is to open the file in Google Drive instead of your email app. Tap the annotate or pen option, draw your signature with your finger, save it, then share it straight back to your landlord. I’ve signed site paperwork that way from my phone plenty of times and it holds up fine. ---

I had this exact problem when I was away from my clinic desk. What worked best on my phone was PDFcap. 1. Open [pdfcap.com](http://pdfcap.com) in your mobile browser and upload the PDF. 2. Choose the sign tool to draw your signature with your finger. 3. Save the signed document and email it straight back. ---

I realised the hard way with my market stall invoices that basic phone viewers will not let you draw. Just take a screenshot of the signature page and use your default photo editor to draw your name with the markup pen. Email that image straight back to them. Avoid trying to convert the file to an EPUB first, as it completely destroys the document layout. ---

Had the same thing last month trying to sign something from a train station. On Android, Google Drive lets you open a PDF and there’s a markup or pen tool where you can draw your signature right on the page, then share it back as a PDF. Saved my evening, honestly. ---

@SneakySteel the Drive pen tool is what I’d try too, just save a copy first so the original stays clean. Worked on my old laptop and my phone, though not sure if it’s the same on Mac. ---

@Emily.7 I agree, saving a copy first is sensible. Grace, try opening the copy in Google Drive, tap the pencil or markup option, add your signature, then use “Save as” or “Send a copy” so the signed PDF stays a PDF. ---

On Android, I usually save the attachment first, then open it in Adobe Acrobat Reader and use Fill & Sign to create a handwritten signature. Place it where needed, save a copy, and attach that saved file to your reply email. If the lease has a signature field, your phone’s PDF viewer may also offer a Sign option, but Acrobat has been the most reliable for me. ---

Yes, this is quite doable on Android. Download the lease, open it in the free Adobe Acrobat app, then tap Fill & Sign, choose signature, draw your name, and place it on the signature line. Save a copy and email it back; I learned the hard way that the email app’s quick markup may not actually save inside the PDF. ---

@emily.7 saving a copy first is the part most people skip, and it’s the one that matters. On my Android I download the attachment to Files, rename it “signed”, then open that copy in Drive and draw on it. That way the original stays clean if your landlord comes back with questions. ---

try adobe acrobat reader from the play store, it’s free. you can add a signature by drawing with your finger then save and email it back. i do lease stuff like this on my phone all the time when i’m not at my laptop.
