Complete Guide to Converting JFIF to JPG
What this tool does
JFIF (JPEG File Interchange Format) is simply a JPEG image saved with a .jfif extension instead of .jpg. The underlying pixels and compression are identical — only the extension differs. Some browsers and Windows apps save downloaded images as .jfif, which can confuse programs that expect .jpg. Renaming usually works, but this tool re-encodes the image cleanly so the result is a proper, universally compatible .jpg.
How to use it
- Drag in your filesYou can add several .jfif images at once.
- Adjust the qualityDrag the quality slider if you need to.
- Click the Convert buttonEach image is decoded and re-saved as a standard .jpg right in your browser.
- Download individually or in bulkGrab everything as a single ZIP when you convert a batch.

Everything happens locally in your browser — your images are never uploaded to a server. The quality slider controls JPEG compression: higher quality means a larger file with fewer artifacts, lower quality means a smaller file. EXIF orientation is applied so photos appear upright, and a white background is used so there are no black edges.

FAQ
JFIF to JPG FAQ
These answers explain what the tool does, what files it supports, and where the current limits are.
Is JFIF the same as JPG?
Yes — JFIF and JPG are the same JPEG image format with a different file extension. This tool re-saves the image with the standard .jpg extension so it opens everywhere.
Are my images uploaded to a server?
No. Conversion runs entirely in your browser using the canvas API, so your files never leave your device.
Can I convert several files at once?
Yes. Add multiple JFIF files and download them individually, or grab all the converted JPGs in a single ZIP.
