Why convert JFIF to JPG
Some browsers and apps save pictures with a .jfif extension. The data inside is a normal JPEG, but many programs, print shops and upload forms do not recognize the extension and refuse the file. Converting writes a plain .jpg that is accepted almost everywhere.
Typical situations
- Uploading a picture to a form that only accepts .jpg
- Opening a .jfif picture in a program that does not know the extension
- Attaching a picture to a document or email without a format warning
What to watch for
A JFIF file already holds JPEG data, so converting it to JPG decodes and saves the picture again, which compresses it once more. At a quality setting of 90 or higher the difference is hard to see. Only the picture is converted, and extra data such as camera and location tags is not copied.
Tips for better results
- Use quality 90 to 95 to keep the picture as close as possible to the original.
- To get a smaller file, choose a maximum file size in the options.
- Renaming a .jfif file to .jpg often works too, but converting also fixes files that were saved with a wrong extension.

Frequently asked questions
Is a JFIF file the same as a JPG?
Almost. JFIF is the file layout most JPEG pictures use, and the pictures inside are ordinary JPEG data. The difference you notice is mostly the .jfif extension, which some programs do not accept.
How do I convert JFIF to JPG on Windows?
Add the files to the converter above and download the JPG files. Nothing needs to be installed. Many programs can also open a .jfif file and save it as JPEG.
Can I convert many JFIF files to JPG at once?
Yes. Add all the files together and download the JPG files one by one or as one ZIP.
Is it safe to convert JFIF online?
Here the conversion runs in your browser, so the pictures stay on your device. In the Network tab of your browser developer tools you can see that no file is sent; the only request after a conversion is a small anonymous count (tool name and language).
Are my files uploaded to a server?
No. The conversion runs in your browser using your own device, so the files are not sent to Convert In Place or anyone else. See how it works for a way to check this yourself.
Is there a limit on file size or number of files?
You can use it as often as you like. One batch holds up to 200 files, and each file can be up to 200 MB. Large files and long batches depend on the memory of your device, and phones handle less than computers.
