Fix for Windows 10 – JPG Files Download as JFIF
If Windows 10 is saving your JPG files as JFIF files, here’s how to fix the problem.
Sometimes Windows 10 saves JPG files as JFIF files. It seems to happen most often when saving images in browsers but doesn’t seem to be limited to them. The cause of the issue is an incorrect file association in the registry which appeared after the Windows 10 Creators update. This can be a hassle for those of us using programs that will not accept that format!
What is a JFIF file anyway? It’s the JPEG File Interchange Format. It seems to have been around since the early 1990’s, which proves once again there’s always something new to learn about computers.
The Fix
The fix is to edit the registry of Windows 10 and change the image association type. BUT….that can be dangerous for those who are not experienced, so I wrote a simple .reg file that will do it for you. Of course, it’s still wise to backup your reg file before using this, but it does work well.
Basically, we are changing the following entry in the Windows reg file. If your comfortable making changes in the registry, here’s the path:
HKEY_CLASSES_ROOT > MIME > Database > Content Type > image/jpeg > Extension > Modify > Edit string > change Value data to .jpg
To make this even easier, just download my jpgNOTjfif.reg file here, pace it on the desktop, double click on it and accept the changes. That’s it! Now when you try to download a file and it has a jfif extension, it will download as a jpg instead.
Enjoy!

How do I download the file? When I click on the “just download my jpgNOTjfif.reg file here” it goes to a new tab like this:
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Classes\MIME\Database\Content Type\image/jpeg]
“Extension”=”.jpg”
It should download automatically. If it is not, this is due to your browser, perhaps try a different one. or you can right click on the link and choose save as.
Thank you so much! It works!
My pleasure.
It won’t let me save. No option given.
Worked great on second browser I tried (google Chrome had trouble and Firefox worked fine) , you saved me a ton of trouble! Thank You!!
My pleasure!
Hi, I used internet explorer and it worked, for those who need…. (when Chrome didn’t work. )
Thank you so much. This worked perfectly. I was able to right-click and save to the desktop and run it from there. The whole process took about 15 seconds and the change took effect immediately. I appreciate you sharing this solution.
Awesome!
Thanks so much for this fix, I couldn’t figure out why Twitter was giving me some crazy format when Reddit wasn’t.
Cool! Happy you found the solution.
Thanks a lot man! worked perfectly.
had to do it on edge though. but thanks a lot.
Thanks. I used regedit to directly make the change. Solved the problem. It’s the second time I solved a problem by making a change to the registry. I was always afraid, I might damage the registry. Knowing exactly what to change makes it simple and safe.
Thank you….worked a charm!
You are a star. Brilliant. From a grateful septuagenarian going mad with this latest lunacy from Windows. Thanks a million
Thank you for this!!!!!!!!!!!!!!!!!!!
Great fix… just worked for me. Thanks.
Thank you soooo much man this helped me alot.
Thank you so much. I got really tired of putting images through conversion websites. You’ve helped me a lot.
THANK YOU!!!! Time saver…was pulling my hair out.
Thank you for sharing this fix! Your script help saved me a lot of time.

THANK YOU SO MUCH!!!!!!!!!!!!! this has been driving me nuts as I work with jpg and have been forced to save as jfif. The fix was instantaneous and you have improved my quality of life and work :))) many thanks. Stay safe and stay well
Thank you. This worked to fix this irritating issue. Like others, the linked file wouldn’t open in Chrome but was successful with Firefox. Fixed the problem immediately.
thank you so much! i was soo confused haha
Thank You! Someone give this man a kiss
Hi there! Thank you SO MUCH for this. Saved me hours of frustration! Didn’t work on Google Chrome so used Firefox and it took seconds to install. Fixed the issue immediately. Thank you!!
Cool!
is this a virus lol
Not that Im aware of! Just a fix
Thanks a lot. It helped!
Hey, has anyone had this issue with the registry already being jpg however still continuing to have images download as jfif? Been trying to search for a solution to quite some time and have not come across anything?
Thanks,
John
Thanks!!! I was going crazy with this stupid thing.
I have the same problem. Would the fix work if I am using Windows 365?
I think you probably mean Office 365, never heard of Windows 365. The file makes changes in the Windows registry, so once that’s done that should change for all programs.
Thanks a bunch! This was causing me such grief, and your fix worked immediately. Great work!
You are the bomb! Bless you! And most of all thank you!
THANKS OMG i have been having this problem over 3 days and it was driving crazy, i was quite unsure to trust this place but the comments and reviews of other people help me, you are a hero dude thanks again
Hi there, in my registry the extension is already set to .jpg but windows is still saving to jfif format. There is another folder under the image/jpeg one called “bits” Anyway not sure what to do here. Thank you in advance
My WINDOWS 10 version only goes to HKEY_CLASSES_ROOT > MIME > Database > Content Type > image/jpeg > then gives me only Bits as an option, not Extension > Modify > Edit string > change Value data to .jpg. Under Bits, there are two files “(Default) – type is REG_SZ – data is (value not set). The other files is 0, type is REG_BINARY and data is 03 00 00 00 ff ff ff d8
Do you have a new solution for Windows 10 Home version 20H2 last updated 6/24/21
thank you
Thank you, worked very well. Please let this not be a virus or affect my computer though. Sorry, but I am very untrust worthy of advice off the Internet.
Thanks so much, sweetie! May you be richly blessed for all you do. 🙂
Thank you!
I tried this and it asks me for an administrator password. Our office locks down things so tight, we can’t even install fonts.
Your fix worked GREAT!! Thank you SOOOO MUCH for saving me the time I would have lost calling Geek Squad … or worse … MICROSOFT!
oh my goodness! i have only now been encountering this damn jiffy lube ext lmaoooo whatever its called. MS is soooo irraz!! i had to delete so many files because of it. but i think they should really compensate you for helping them from many pissed off people lol lolanywho, mahalo nui loa ( thank youuuu sooo much)!! this really worked!! Amazing 🙂 You are Awesome!!
thank u so much, it works
worked, thank you! if it’s not downloading (tried it in both chrome and edge, neither worked) do right click on the page>save as reg)) then open the file.
I opted to change the registry, typing in regedit ….then followed your instructions. ….when I clicked on the image/jpg , was a bit confusing, I was expectiong to see another folder. But in the window was the file, “extension” and I right clicked on it a menu came up with the choice “modify”. Then I clicked on that and a little window came up that said “edit string” ….then I could change the .jfif to .jpg and that was all there was to it. It worked perfect ! thank you.
I believe this is the best fix I got on the internet for a problem. There were 3 warnings given by windows, so I pressed “No” and came back here to check the comments. I finally trusted it & gave it a shot & damnnnn, it worked like a charm. Thanks, I was really annoyed for the past 1 week. Many thanks.
thanku so much its working.
its 2022 I thought this blog is fishy, until I tried it edit in reg and it actually works by following your steps! Thank you so much for creating this blog!! this would definitely have big help other people around the world! 😀
Thanks for this buddy.
worked thank you
Thanks, it really worked, now I can download jpg files without Discord suspecting any jfif files, discord won’t display jfif files.
Your advice on how to turn images back into jpg format in aol mail was great! Next problem: every image sent is renamed as “thumbnail.” I much prefer having the name by which the picture was sent, ie “20220722_153241,” or “img1429,” or even “SamAtLunch.” How do we fix this problem?
I want to say only one thing you’re AWESOME
All you have to do is change jfif to jpg and accept and it works just fine. I just did it to make sure and it works and I can even open it on photoshop then.
I must be doing something wrong. When I click on the link it only presents a text file in another tab in both Chrome and Edge browsers in Windows 10 Pro. What browser will work to execute this file, or is there another work around? Thanks.
Great! Thank you so much. Easy peasy with your help.
thanks for the fix, man.

Beautiful! Many things turn out to be harder and longer than expected, but your help made this easy – still working in 2023 from bristol Uk, thank you 🙂
After downloading it my pc doesnt know what app tom use to open it.
Thank you so much!
I just used Run – > regedit and paste that string into top bar:
Computer\HKEY_CLASSES_ROOT\MIME\Database\Content Type\image
Then double tap on Extention, change value to .jpg as above and OK.
Thank you again 🙂
Thanks! This worked perfectly. Immediately after installing this Reg file when I saved files from the web they stopped being jfifs and became jpgs. You saved me a ton of time having to take each jfif file and convert it. You are an awesome person for putting this out there for all of us to use for free.
