JFIF (JPEG File Interchange Format) is technically the same as JPG — both are JPEG compressed images. The only difference is the file extension. But that tiny difference causes real problems: many apps, messaging platforms, and websites refuse to open or upload .jfif files, even though the image data inside is identical to a standard JPG.

Our JFIF to JPG converter solves this in under a second, entirely inside your browser. No file upload. No account. No waiting for a server. Your image is decoded using your browser's built-in engine, drawn onto an HTML Canvas, and exported as a standard .jpg at 95% quality.

Why does Windows save images as .jfif? When you screenshot something in Chrome or download images from certain sites on Windows, the browser saves the file with a .jfif extension. This is technically correct behavior, but it breaks compatibility with practically everything else.

Quality: Since both JFIF and JPG are JPEG format, conversion involves re-encoding at our default 95% quality setting. The visual difference from the original is negligible for most images.

Frequently Asked Questions

Why does Windows save images as .jfif instead of .jpg?⌄
Chrome and Chromium-based browsers on Windows use the MIME type 'image/jpeg' to determine the file extension when saving. For JFIF-encoded images, Windows maps this to the .jfif extension. It's the same image data — just a different extension.
Will converting JFIF to JPG lose quality?⌄
Re-encoding involves a minor quality step since JPEG is lossy. We use 95% quality by default, which is visually indistinguishable from the original for virtually all photos and screenshots.
Can I open .jfif files on my phone?⌄
Most phones don't recognize .jfif files natively. Converting to .jpg solves this instantly — JPG is supported on every device and platform.
Is it really free? Are there any limits?⌄
Yes, completely free with no limits. You can convert as many files as you want, as large as your device's memory allows. We don't have a server to run, so we have no reason to charge or impose limits.
Do you upload my files to your server?⌄
No. All conversions happen locally in your browser using the browser's built-in image APIs. Your files never leave your device. We do not have servers that process files — by design, not by promise.
What is the maximum file size?⌄
There is no hard limit set by us. The only constraint is your device's available memory. Most modern devices handle files up to several hundred megabytes without any issues.
Do I need to create an account?⌄
No account required. We don't have a user system. Open the page, drop your file, download the result — that's it.
