Question

All my pictures .jpeg have been converted to PDFs why?

All my pictures .jpeg have been converted to PDFs and when I click on them I get the following error message: Adobe Reader could not open because it is either not a supported file or because the file has been damaged (example, it was sent as an email attachment & wasn't coded correctly.)

I am trying to open them from the File Explorer /pictures/ and the 'Type' column reads Adobe Acrobat. I have never changed any .jpegs into adobe.

When I open Reader and look at Pic File Folder nothing shows up. This seemed to have happened some time in the last couple of weeks.

I am using Win 8, all up to date , ASUS laptop, Chrome

All of my pics on my Windows 10 did the same thing and I am mad. It automatically did it without asking. Now I have a bunch of PDFs that I have to change back to jpeg or other formats to easily resize. Thanks a lot Adobe for ruining my life.

I'm willing to bet they didn't change. Reader isn't even technically capable of doing that.

It's the file-extension association that got changed, by accident. See above how to fix it.

Some software glitch did this, but it is easy to correct it. I had the same problem for several weeks. Here is what I did: I right-clicked on the image thumbnail. Then I clicked on “Open with”. Don’t click on the intended editing or viewing program on this list yet. Just click on “Choose another app”. This will open a dialog box with a list of programs including your favorite. At the bottom of the dialog box check the box “Always use this app to open jpg files”. then hit “OK”. This will do the trick for all you changed jpg files.
Note: Your pdf files WILL NOT BE AFFECTED.

thank you for a short and straight forward solution

Unfortunately this issue does arise after downloading Adobe DC Reader

If you have a Windows 7 OS machine, you may want to try opening any "apparently converted" jpeg to pdf file by....(1) Right Clicking on the "pdf" file....(2) Click on "Open With"....(3) Then, choose from the App. Software program choices...."Windows Photo Viewer"......This would open the so-called pdf file in "jpeg" mode......You would also note that all your "jpeg" have returned to their "jpeg" file extensions.

Note: this will not change the file extension!

I am having the same problem - all my photos have been converted to PDFs. I don't want to get into changing file extensions. This must be a defect in Adobe Reader DC. I guess the only solution is to go back to Microsoft Edge

No. Not a defect. Please see the very first answer in this thread. Your file associations need to be changed.

That link that you provided just takes me to MS Help. I asked them and they were much more helpful than Adobe help. I was able to fix the problem. Thanks for steering me in the MS direction for a solution

Have read discussion however I think my problem is with windows 10. All jpegs converted but to .HEIC.

When I went to Properties; Type of File - Adobe Acrobat Document; Open With - 1 choice and when clicked on it said "No result found for this filter". Now what???? Help.

With some more delving and reading I have that iOS 11 uses the .HEIC format. See https://fileinfo.com/extension/heic .

I downloaded the free download CopyTrans for HEIC for Windows and it worked. Now am having trouble with .MOV extensions.

I get audio but no video.

I had the same problem. Just right click on any jpeg photo and look for "open with"- change from adobe to windows player. Done, all your photos will now open like they use to!

i too have just found out that all my photos in jpg format have been changed to pdf format on my iphone and on my main computer without me knowing it. There are thousands of photos. I only found out when i tried to edit a photo and my editor would not let me do it. Does anyone know why or how this has happened? I have not changed anything at all. I am pretty angry about this as i wanted to keep my photos in jpeg format.

Since your issue is completely different than the original poster's (iOS works very differently from Windows), please start a new topic in https://forums.adobe.com/community/adobe_reader_forums/ios

Or better contact Apple, as this does not seem to be an Adobe Reader issue. Adobe Reader does not have any ability to convert or rename files.

Sorry i may have been confusing two issues here. The main problem i have has nothing to do with iphone, it concerns my main computer running Windows 7. i have many thousands of photographs going back to 1995 and yesterday i noticed that all of them have been converted from jpeg to pdf -- All of them! When i look for a solution on the internet it says get a converter programme to turn pdf into jpeg. But there is something fundamentally wrong when my computer has done the conversion without me knowing and without me doing anything different. I fear that all my high resolution photos are now 'lost' in low resolution pdf files. I run Adobe Acrobat XI Pro and so i assume that this may have something to do with it - the programme automatically upgraded recently. But i may be wrong of course and it maybe a Windows 7 issue. But if anyone can point me in the right direction please. My issue with iphone was that i also noticed that my iphone has suddenly started saving pictures as pdfs as well. this may be connected to my main problem.

It just sounds like your file associations got out of whack and you need to change them back.

Here is a MS Knowledgebase document on how to change them so the proper application will open your .jpg files.
