Why convert JFIF to PNG?
Windows often saves images from the web with the .jfif extension, and many upload forms, editors and phones do not recognise it. PNG is lossless and supports transparency, which makes it ideal for graphics, screenshots and further editing.
What changes when you convert JFIF to PNG
- PNG files are usually larger than JFIF files, because PNG stores the image with less (or no) lossy compression.
- PNG is lossless: every pixel of the decoded image is preserved exactly.

JFIF to PNG: questions & answers
Is converting JFIF to PNG free?
Yes, completely free with no sign-up, no watermark and no daily limit.
Will I lose quality converting JFIF to PNG?
No. PNG is lossless, so the converted image keeps every pixel exactly as it was decoded from the JFIF file.
Can I convert multiple JFIF files at once?
Yes. Drop as many files as you like; they are converted in parallel and can be downloaded individually or as a single ZIP.
Are my JFIF files uploaded?
No. The conversion runs locally in your browser, so your images never leave your device.
Does it work on iPhone and Android?
Yes. The converter works in current versions of Safari, Chrome, Firefox and Edge on phones, tablets and computers. Very large images may exceed the memory available to mobile browsers.
Why do my images save as .jfif?
On some Windows PCs the registry associates the image/jpeg content type with the .jfif extension, so the browser uses it when saving JPEG images. The image itself is a normal JPEG.
