How to convert JFIF to JPG

  1. Drop your .jfif images on the box above, or choose them. One image or a whole folder of them.
  2. There is nothing to set: the picture is kept exactly as it is.
  3. Each image converts on this device straight away, with its old and new size next to it.
  4. Download one file, or all of them as a ZIP.

What is kept, and what changes

DetailIn your JPGNotes
The pictureExactly the same, byte for byteA .jfif file is already a JPG inside, so nothing is re-encoded and no quality is lost.
Photo details (EXIF)KeptCamera, date and any location details stay in the file, as they were.
File nameSame name, ending in .jpgphoto.jfif becomes photo.jpg, which every upload form accepts.

Problems and fixes

"FileInto couldn't read this image"
The file may be damaged, or not really a JFIF. Open it in your photo app; if it shows there, save a fresh copy and try again.
It is slow with hundreds of photos
Large batches use every core of your device but still take a moment per photo. Keep the tab open; the images convert a few at a time and the ZIP is built at the end.

Questions

How do I convert JFIF to JPG?
Drop your .jfif images on the converter on this page. They convert in your browser straight away; download one JPG, or all of them as a ZIP. No sign-up and no upload.
Is this JFIF to JPG converter free?
Yes. Every image converts free, and up to 10 download at a time without an account. For bigger batches, a Day Pass or Unlimited removes the limit.
Are my images uploaded anywhere?
No. Your browser decodes and re-encodes each image inside this tab. Your file never reaches our servers, and nothing about it does either: not its name, its size or how many rows it has.
Why convert JFIF to JPG?
A .jfif file is a JPG with a different ending. Windows often saves pictures from the web this way, and then many upload forms refuse them. JPG is the safer choice for email, uploads, printing and any app.
Can I convert many images at once?
Yes. Drop as many as you like, or a whole selection from a folder. They convert a few at a time on your device and download together as one ZIP.
Does it work on iPhone and Android?
Yes, in current Safari, Chrome, Edge and Firefox, on phones and computers. On a phone, choose the images from Photos or Files.
What are the limits?
Images up to 50 MB each. Every image converts and shows its new size free. Up to 10 images download at a time free, no account needed; a Day Pass ($9 for 24 hours) or Unlimited ($7 a month) has no limit. It works in current versions of Chrome, Edge, Safari and Firefox, on computers and phones.
