How it works
Add your images
Drag and drop, paste, or pick files. They upload over an encrypted connection.
Pick a quality or a target size
Use the quality slider, or tell it exactly how many KB or MB you need.
Download
Save each file, or grab them all at once as a ZIP.
A .jfif file is a JPEG. JFIF stands for JPEG File Interchange Format, the wrapper that nearly every JPEG picture has used since the early 1990s, and the data inside is identical to what a .jpg holds. The only unusual thing about it is the last four letters of its name. Unfortunately those letters are what many programs and upload forms look at, and a file they do not recognise by name is turned away.
Add your .jfif files here and each comes back as a .jpg. The picture is saved again at quality 92, where no difference is visible, and metadata such as location is removed by default. Twenty files at a time work without an account, and the batch downloads as one ZIP.
If you want the picture untouched to the last bit, switch the mode to Lossless. JPEG has no lossless re-encoding, so in that mode the original data is handed back as it is, under a name ending in .jpg, which is exactly what is needed here. Files travel encrypted to our own servers and are deleted within the hour.
Where .jfif files come from
Almost always from saving a picture out of a browser on Windows. When Chrome, Edge or another browser saves an image, it asks Windows which ending belongs to the type image/jpeg. On many Windows 10 and 11 computers a system setting answers .jfif instead of .jpg, and so every photo saved with Save image as arrives with that ending. Nothing is wrong with the website or with the picture.
People notice the moment they try to use the file. A shop's product uploader lists JPG, PNG and GIF. A print kiosk shows an empty folder. An older editor does not offer the file in its Open dialog. The picture itself is fine, and the name is the whole problem.
Renaming works too
Because the contents are already JPEG, you can change the ending by hand and nothing else needs to happen. In Windows Explorer, switch on File name extensions in the View menu, select the file, press F2 and replace .jfif with .jpg. Windows asks you to confirm the change; go ahead. The file opens everywhere a JPG does.
Use this page when that is impractical: on a phone or a work computer where endings are hidden, when you have forty files and not one, or when you want the pictures compressed, resized or stripped of metadata in the same pass. In the Save dialog of the browser you can also choose All files and type a name ending in .jpg, which avoids the problem for that one download.
JFIF, JPG, JPEG, JPE: one format, several names
The standard that defines the compression is called JPEG, after the committee that wrote it. Early Windows allowed only three letters in a file ending, which gave .jpg, and other systems used .jpeg. JFIF is the name of the simple file layout that wraps the compressed data, and .jpe, .jif and .jfi are rarer spellings from the same family. All of them are accepted on this page and all come back as .jpg. Cameras wrap the same data in a slightly different layout, Exif, to carry settings and location. That is why a photo from a phone has metadata and a picture saved from a website usually has none.
Frequently asked questions
Is a JFIF file lower in quality than a JPG?
No. It is the same compression and the same data. Only the name differs.
Can I rename .jfif to .jpg instead of converting?
Yes, and the picture stays bit for bit the same. Converting here is for batches, for devices where renaming is awkward, and for when you want to compress or resize as well.
How do I stop my browser saving pictures as JFIF?
The cause is a Windows setting that links the JPEG type to the ending .jfif. An administrator can change it in the registry. Until then, type a name ending in .jpg when you save.
Does converting lose quality?
At the starting quality of 92 the picture is encoded once more with no visible change. In Lossless mode the original data is returned unchanged under a .jpg name.
Can I convert JFIF to PNG or WebP instead?
Yes. Choose the format in the editor before you download. PNG gives a lossless copy and a larger file, WebP a smaller one.
Does it work on a phone?
Yes. Open the page in the phone's browser, pick the files and download the JPGs. Nothing has to be installed.
