How to convert JFIF to JPG

  1. Add your JFIF filesChoose .jfif files, drop them in or paste an image. They convert immediately.
  2. Keep the defaults or re-encodeBy default the picture is not re-compressed, so quality is untouched. Tick Re-encode if you want to set a quality value, or Keep metadata to retain camera data.
  3. Download the JPG filesSave each file or press Download all (ZIP) for a batch.

What is a JFIF file?

JFIF stands for JPEG File Interchange Format. It is the small wrapper, published in 1992 and later standardized as ITU-T T.871, that lets JPEG picture data travel between programs, and nearly every .jpg you have ever opened is technically a JFIF file. The picture inside is ordinary JPEG. The .jfif extension appears mostly because of how some software names things. Saving an image from certain browsers on Windows is a common way to end up with one.

The odd extension is the only real problem. Websites, phones, editors and print services often check the extension and refuse .jfif even though the content is a perfectly normal JPEG.

The JPEG data is kept as it is and saved with a .jpg extension. (JFIF, JPG)

Does converting JFIF to JPG lose quality?

No, not by default. Because JFIF already is JPEG, there is no reason to decode and compress the picture a second time, and every re-compression costs a little quality. This tool copies the compressed image data as it is into a new .jpg file. The result looks identical, and the file size is almost the same.

Choose Re-encode only when you want a different quality setting, for example to make the file smaller. That path decodes the picture and saves it again at the quality you select.

Metadata and rotation

Unless Keep metadata is ticked, EXIF, XMP and comment blocks are stripped, so location and camera details do not travel with the file. Color profiles are retained so colors do not change.

One case needs care. If a picture is displayed rotated only because of an orientation flag in its metadata, removing the metadata would turn it sideways. In that case the tool re-encodes the photo upright instead and tells you in the file row.

  • Any JPEG file works as input, whatever its extension.
  • Files up to 50 MB, with 30 per batch on a computer and 15 on a phone.
  • To shrink a JPG afterward, use the compress tool.

Questions

Is JFIF the same as JPG?

For practical purposes yes. JFIF is the file wrapper for JPEG data, and a .jfif file contains an ordinary JPEG picture.

Does converting JFIF to JPG reduce quality?

Not by default. The image data is copied without re-compression. Quality only changes if you tick Re-encode and lower the slider.

Why do I get JFIF files when saving images?

Some browsers and apps on Windows save JPEG pictures with the .jfif extension. The picture is fine, only the name is unusual.

Does the tool remove location data?

Yes, unless you tick Keep metadata. Photos that depend on a rotation flag are re-encoded upright so they do not turn sideways.

Can I just rename the file myself?

Often yes, and the result is the same picture. This tool does the rename for many files at once and can also remove metadata.

Are my files uploaded?

No. Everything happens in your browser and no file leaves your device.
