I took a few screenshots of my receipts on my Android and they saved as PNG files, which the expense portal will not accept. I tried just renaming the file extension to PDF in my gallery, but that broke the file and now it will not open at all. What is the easiest way to actually convert these PNG images into a real PDF right from my phone? ---

That is annoying, but renaming only changes the label, not the file itself. On Android, open the screenshots in Google Photos or Files, choose Print, then select “Save as PDF” and save it somewhere you can find it. If you need several receipts in one file, select them first and use the same Print option; I do this fairly often for marked practice sheets. ---

Had the same thing last month. Renaming the extension just breaks it because it is still a picture file. I drop the PNGs into Google Drive on my Android, open one and hit Print then Save as PDF. Worked fine for my reports. ---

Renaming only changes the label, the file inside is still a PNG, so that is why it broke. What I do on my Android is open the screenshot, tap the 3 dots, pick Print, then set the printer to Save as PDF. It saves a real PDF the portal will accept. ---

Renaming the file extension definitely won’t work, it just stops your phone from being able to recognise the image. For my site receipts, I just load [pdfcap.com](http://pdfcap.com) in my mobile browser. You can upload all your PNG screenshots there and it turns them into a proper PDF document. Give that a try and let me know if the portal takes it alright? ---

@nicholasb23 That Print then Save as PDF trick is exactly what I show patrons at the library, works on most Android phones without installing anything extra. One tip: open the saved PDF before you delete the original screenshots, just to be safe. And definetly avoid renaming extensions again, I learned that the hard way with a tax form once. ---

if you already have google drive, you can upload the png, open it with google docs, then download as pdf. even simpler on most androids: open the image, tap share, choose print, then save as pdf. no extra app needed for either one. ---

Renaming the extension never works, you actually gotta convert it, not just relabel it. 1. Open AltoSignPDF app or site on your phone. 2. Upload the PNG screenshots. 3. Convert to PDF and download. Keep the original PNGs as backup just in case the expense portal wants to double check something later. ---

@nicholasb23 That three dots then Print path is the one I use too, it saved me when our grant portal rejected a batch of receipt screenshots. One thing I would add: after saving, rename the PDF to something the portal likes before uploading, since some systems choke on long screenshot filenames. And agree on keeping the originals until the expense report clears.
