Convert JFIF to PNG
JFIF is a JPEG variant that Windows and Chrome sometimes save. It is technically the same as a JPG. PNG is the practical destination when JFIF is the thing standing in the way, because PNG is built for logos, screenshots and graphics with transparency and almost every program opens it. Worth knowing before you start: PNG is lossless, so it preserves exactly the pixels that came out of the JFIF file. It cannot restore detail the JFIF encoder already discarded, and the file will usually get larger, not smaller. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.
Drop your JFIF files below and download PNG in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.

Why convert JFIF to PNG?
JFIF is the original container name for JPEG files, and Windows or Chrome occasionally save images with the .jfif extension. The data inside is regular JPEG, but the unusual extension confuses many apps and upload forms. Renaming sometimes works, converting guarantees a file every tool accepts.
PNG stores every pixel exactly as it was saved, which makes it the safe choice whenever detail matters more than file size. It supports a full alpha channel, so logos and UI elements keep clean, soft edges on any background. The tradeoff is that photos saved as PNG can get large.
JFIF vs PNG at a glance

What changes when you convert JFIF to PNG
| What happens | |
|---|---|
| Image quality | Unchanged from here on. PNG is lossless, so it preserves exactly the pixels decoded from the JFIF file. It cannot restore what the JFIF encoder already discarded. |
| Transparency | JFIF has no alpha channel, so there is no transparency to lose. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the PNG file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. JFIF files here are single images. |
| File size | Larger, often several times. Lossless formats cannot match what a lossy encoder already achieved. |
