JPEG to JFIF automatically! HELP!

by missdawn215 / November 7, 2016 11:26 AM PST

Been working on my website and blog and this issue is wearing me out! Any JPEG image I download is automatically converted to a JFIF file when saved. It was random at first, but now it is doing it regularly and my uploaders for my sites won't recognize JFIF files. I keep having to go to converters online, which don't always work. It's needless and time consuming and is pissing me off! I am not very tech savvy, but I get by. I even tried to open them in paint and rename/save them. NO LUCK! Still a JFIF file. Is this a Windows 10 thing? A Chrome thing? I just want it to stop.

Any suggestions on what this is, why it's doing this and how to fix it??

Thanks in advance and please excuse my rant!!

Kindly, Melissa

Clarification Request
Just last week.

I had a very confused client that took time to grasp that a file extension does not need to match the file association. I don't know how long you've used Windows or if you are looking at the file extension or the misleading Explorer file type.

Tell more.

Re: jpeg and jfif

In reply to: Just last week.
http://www.fileformat.info/format/jpeg/egff.htm tells about jfif (jpeg file interchange format). Any hex editor (I'm using hxd) lets you look inside the file to see if it's jfif indeed. Also have a look at the original file to see if they are different or the same. If they are the same, just rename.

It's not really clear from your post what you or 'uploaders' up- or download from what to what using what programs, and what platform your website and blog are running on/written in.
But I've never seen a binary ftp to a site changing a file extension, nor in fact, a download from a site to my browser.

Thanks for responding! I'm using Ipage for my website and this also includes WordPress for my blog. All I am doing is finding images to use and saving image as (im making sure they are JPEG/JPGs) and then when it is downloaded, the little download box will name it and put it as a JFIF. I have tried changing it/resaving it in paint as a JPEG but it wont do it. When I go to upload the image, I am told that there was an error, that this format is not recognized. Apparently it is a more recent problem because I am seeing people posting the same issue throughout various forums and online with little to no answers. Sorry I am not really technical to explain it!

This is my exact scenario. . . editing my own photos, which have been turned from .jpg files to JFIF, and won't upload to wordpress. Following for a good answer! Thanks!

JPEGs downloaded stored as JFIF
by ptharago / June 26, 2017 11:12 AM PDT

I discovered this happened as a result of the windows creator update. Every jpeg file identified by the browser as a jpeg when it is downloaded from the web is saved by windows 10 creator as a JFIF file which nearly nothing recognises. However I started a command window navigated to the offending files and using the ren command renamed the files to end with jpg and they now work correctly and will be opened by everything as normal. I t would be very easy to write a little batch file to do this for multiple files if the probel is a big issue. But who knows what Microsoft were dreaming about. I have tried 3 different browsers and behaviour is in all 3.

Jpegs coverted to Jfif
by dcblogic / August 8, 2018 6:08 AM PDT

Hi. I am having this problem, and not being "techy" at all, I didn't understand your instructions. I take the pics with a Galaxy S7 (yes I know, I need a new phone) and email to myself, windows based computer. I then upload to a real estate site, MLS. It converts the pic to a .jfif, which MLS does not recognize.
Is the problem with my phone or computer and how shall I correct?

Re: jpeg converted to jfif

In reply to: Jpegs coverted to Jfif

It's not the file that is converted, it's just the extension that is changed to .jfif. All you have to do: rename it back to .jpg. Renaming a file is basic Windows knowledge, isn't it?

by rentur3 / August 12, 2018 4:18 AM PDT

That response seems unnecessarily rude. Removed the extension from the file name has no effect, in this scenario the file extension is automatically reassigned, and removing the file extension from the name doesn't effect the problem.

Kees has it spot on.
by R. Proffitt Forum moderator / August 12, 2018 7:43 AM PDT

I'm running into more and more users that don't want to learn about computers. They operate at a severe disadvantage and some of them flame anyone that suggest they learn more.

Kees wasn't rude at all except it may be taken as rude to those that want computers to work without learning how computers and Windows works.

Jpegs converted to Jfif

In reply to: Jpegs coverted to Jfif

Hi dcblogic! I'm not "techy" either and this problem has been making me crazy as well. By reading through this thread I was able to easily solve the issue. Go to your pictures folder, right click on the image you are using, click on rename, add .jpeg to the image name. It doesn't matter that under TYPE it is still showing as a jfif file. Try using the image. This worked for me and is a non "techy" easy solution.
Later... tried it again, didn't work! Grrr

I checked my registry, and it already contained .jpg.
I wonder why it's sometimes changed.

JFIF back to JPEG as default - LIFE SAVER - thank you!

In reply to: Win10 Solution

This fix worked perfectly. I noticed this undesirable & frustrating situation last week when a friend texted a photo of the group of us at a concert. Could not edit or change the extension with the limited knowledge this problem & the available software programs on my computer. Then I noticed ANY photo or image I downloaded was also being saved automatically with the .JFIF extension. Total nightmare.

I AM SO GRATEFUL for your post. Thank you again!

It's actually quite simple, go to the image properties and rename it to have .jpeg at the end instead of .jfif it works every time

Download pic, then rename it.
by Daisy_Jane / August 9, 2018 4:07 PM PDT

I couldn't understand all the tech answers below, either, but I found that if I downloaded the pic first and then named it, I didn't have this problem. In other words, when you go to download the pic and you have the option of re-naming before the download, it switches to jfif. Download it first, then go in to your pictures, find it and name it what you will <3
