Images uploaded through teams convert to PNG's upon download
Hi all,
I'm having an issue on teams, where images uploaded from a mobile phone (.jpg's) download on a computer as .png 's . When I open them in Photoshop I get the error that's attached. I've gone manually through file explorer and renamed the extension on the downloaed image back to .jpg and that solves the problem. But this is a major issue for my team, as one of our primary uses for teams was to be sending images from phones into chats to be downloaded and edited... Any tips?
I have tried:
Manually changing the image handing settings in teams to upload full-size images (this does result in a full-size image, but still has a filename change)
Any advice at all would be greatly appreciated! Thank You.
- That's odd. Seems like a bug to me. I would submit a support ticket.
As a work around, since Teams is attached to SharePoint libraries you can use the OneDrive App to upload your photos. You can quickly take photos as well using the app where you can upload them to a channel folder for access into Teams.
I created an account to help spread the word on this issue. As a designer, this creates several problems. As others have pointed out, Teams renames any JPG shared to "Microsoft Teams Image.png," and does don't actually "convert" the image to an actual PNG, but rather changes the file extension. It should be obvious that you shouldn't just change the file extension to something else simply by renaming it, even if it "still works." JPG uses lossy compression, PNG uses lossless. They are not the same thing. Then, changing the file name completely disrupts the workflow of every creative team I've worked on who works hard to establish, train, and follow file naming conventions. The file names contain breadcrumbs to where the native art files are stored. That, and we often share multiple versions of artwork which is noted in the filename. Microsft, please fix this issue for the sanity of all creatives using Teams as their chat app.
- Hi every one, it is unbelievable, but Microsoft fixed this issue. They reselased completely new App, the icon has "NEW" inside and this new version upon downloading image from chat displays the same dialog as they use in Edge browser and the image is downloaded with original name unchanged 🙂
The name and version of the app is "Microsoft Teams (work or school) - Version 23285.3804.2469.4861"
It took just MS only 4 years to solve this 😄 but I'm glad now it is working properly.- Thank you! I've just installed the NEW Teams and I can confirm JPGs are downloading correctly, with the correct extension.
nothing stops to to open Command Prompt and do bulk rename, something like:
ren *.* *.jpg
- It's the future and this is still a problem. BUT I have a workaround fix for you to batch rename all those PNGs to JPGs.
1. Go into a folder where you want to rename them and
2. Create a new Notepad text document and
3. Save it as Rename.bat (or whatever you want to call it, just save it as .bat)
4. Write this and only this in the text file:
ren *.png *.jpg
5. Save it. Close it.
6. Double-click it in the folder and magic will occur. Hope it helps.
Yo Microsoft! Fix this please.BLPax8 only way that’s working is if you are syncing the folder locally with OneDrive client.
- Mircosoft, FIX this issue... it's 2023..
- This is a bug. This is against JPEG and PNG formats, because you cannot have JPEG content inside .png file.
This fails our content-based image validation in our web app, because file content does not meet file extension. This is security issue for us.akurov ended up here for the same reason. Our tester was using jpg images from his phone transferred via teams, and the tests were failing because the file extension (png) matched the acceptance criteria, but the validation was actually doing what it was meant to be doing and failing files with extensions that don't match the byte signature. Caused a bit of confusion for a bit until I found this post - now just need to explain it all to the client....
I was able to keep/save the image as a jpg by downloading it; open the download then go to Share choose Snipping Tool and save it from there. Hope this helps blastoffmax
- Why would you need to do this "I was able to keep/save the image as a jpg by downloading it; open the download then go to Share choose Snipping Tool and save it from there." You just need to rename the file extension and not re convert a file format. The data in the file is untouched, your solution does not fit the problem. <Right click> rename, don't get the opening between 2 programs
Cannot believe how this problem can still exist years later! So, upon downloading an image from Teams that was uploaded as a JPG, Microsoft CHANGE the filename (not the file) to MicrosoftTeams-image.png.......... Have you heard of ANY other modern app doing such a thing? Imagine downloading an image from Slack and it just randomly changed the image?? And this wasn't the case years ago, it downloaded and displayed in Teams as you would expect, and then, in one update, it broke it all. Then they slightly fixed how it displays in the post issue (still crops it off weirdly at times) but it still downloads as MicrosoftTeams-image.png. HOWWWWWWWWW?!?!?
Download multiple files and you get MicrosoftTeams-image (1).png! How is this ok? It creates confusion, it creates errors when colleagues try to use the image in other apps and it wastes time as we have to explain the stupid Microsoft behaviour to their perplexed faces.
Fix the **bleep** bug already!!!!
- I have since discovered, if you DON'T click on the image and enlarge it, you can right click on the thumbnail in the post and select download and it keeps the filename and extension intact. Why this same behaviour can't be afforded to the download button when you click on an image is beyond me.
- fwiw, I definitely agree that this is a bug. But I'm finding that if you go to the incredible annoyance of right clicking the image thumbnail and selecting Open in Browser, it opens in the browser in the correct format with the actual name (instead of MicrosoftTeams-Image) and can be saved that way.
This is still... fully unacceptable in terms of what is expected of the app.- It is still an issue 2.5 years after the original post. How bizarre this isn't addressed for something so simple yet essential to the platform? I guess not many organizations use Teams? maddening.
- For the record, I have the same problem. It's dumb and a waste of time that it renames JPG's with the wrong extension. Don't see why MS says that's not a bug.
Having to download all images click by click singly is a royal pain in the butt. Having to convert all faulty PNG's back to JPG's is just a cherry on top.
This is embarassing, that such a key feature of a work-space App lacks functions that are important to so many of us working with websites, content creation and digital formats.
And I know that our company pays way too much for this kind of Solution. I recommend to stick with Slack until this problem is solved. It saves more time and time is money.- For me it's bigger issue as a web developer. The file is not "converted" rather than just renamed, thus ending with wrong extension. To fix this I have to rename every single downloaded file accordingly to original name.
I've reported this bug directly to MS Teams developers team through our paid support and their reply was: "It's not a bug, it's defined by design of the app. We recommend to use UserVoice to suggest the change.". I've posted to UserVoice, but I still think it's a bug.
