Features
JFIF to JPG in one click
Drop in your JFIF files and download clean JPG images — batch several at once, each named to match its source.
Nothing is uploaded
The conversion runs entirely on a canvas in your browser, so private photos, screenshots and scans never leave your device.
No signup, no watermark
There's no account to create and no watermark stamped on the result — just the converted image, ready to use.
Quality control
A quality slider lets you trade a little sharpness for a much smaller JPG file when you need to email or upload it.
Handles transparency
Transparent areas are filled with white by default (you can turn it off) so they don't come out black in the JPG.
How it works — in four simple steps
No signup, nothing to install — it all runs in your browser.
Add your JFIF files
Drag your JFIF images onto the box, or click to browse and select them — one or many.
Set the quality
Drag the quality slider to balance file size against sharpness for the JPG output.
Convert to JPG
Press Convert — each image is redrawn and re-encoded as JPG on your device.
Download
Preview the results and download each JPG image, ready to use anywhere.
How it works
This converter turns JFIF images into JPG right in your browser. A .jfif file is simply a JPEG saved with a different extension — Windows sometimes produces them when you save an image from a browser — so converting it to JPG just re-wraps the same picture in the format you actually want. Load one or many files, and each is drawn onto an HTML canvas and re-encoded as JPG. You can set the output quality to balance sharpness against file size. Because JPG has no transparency, any transparent areas are filled with white (you can toggle this) so they don't turn black.
Nothing is uploaded — the whole conversion runs on your device using the browser's built-in image engine, so it's fast, private and works offline once the page has loaded. There's no signup, no watermark, and no limit beyond your device's memory.
