PDF files I open in Adobe Acrobat that I share with a WhatsApp recipient transfer as BIN files

Have you tried to share a PDF file with WhatsApp to a desktop computer system? What kind of results do you get then?

Can you open the PDF file independent of the BIN icon on your phone?

My suspicion is that you’re still dealing with .pdf files all around, and contending with an idiosyncrasy of how WhatsApp creates a nonstandard icon and not an issue of what type of file you’re sharing on the WhatsApp platform through your Android phone. Fortunately it’s only disappointing and not actually affecting the file format or content you’re working with here. As you report, there’s no icon misidentification if you use other sharing platforms.

• Device: Samsung Galaxy A32.

• Operating system: Android 13.

• Both Adobe Acrobat Reader and WhatsApp are updated to their latest available versions.

• Problem occurs with every PDF shared directly from Acrobat using WhatsApp.

• The filename retains the .pdf extension, but WhatsApp displays a BIN icon.

• Sharing the same PDF through Samsung My Files works correctly.

• Opening the document again through Android's Open With → Adobe Acrobat, then choosing Share → Send a Copy, also works correctly.
