About JFIF to PNG
A .jfif file is a JPEG image with a less familiar extension, often created when saving pictures from a web browser on Windows. When you need a PNG instead, for a design tool, a presentation or a site that only accepts PNG uploads, this converter handles it. It decodes each JFIF image, applies any rotation stored in the file, and writes a lossless PNG that won't degrade if you edit and save it again. Resize and rename as you go, process several files together, and download the whole set in one ZIP archive.

Questions
Why do I have JFIF files at all?
Windows associates the JPEG format with the .jfif extension in some setups, so images saved from websites can be given that extension even though they are ordinary JPEGs.
Will the PNG be larger?
Usually, yes. PNG stores the decoded image losslessly, which takes more space than the JPEG compression inside a JFIF file.
Can I convert many files at once?
Yes. Add as many as you like. Each shows its own progress, and Download all puts every converted PNG into one ZIP file.
Is anything sent to a server?
No. The site is static: it delivers the page and the converter code, and all file processing runs locally in your browser.
