JFIF to PNG Converter

JFIF is really JPEG with a .jfif name — and plenty of sites and apps refuse it. Convert it to a universally accepted PNG here, one file or a batch at a time, without uploading anything.

Drop one or more JFIF files here, or click to choose

.jfif, .jpg and .jpeg are accepted. Each file is converted in your browser — nothing is uploaded.

Files are checked by their actual content, not just the name: if a file only pretends to be JFIF, you will see exactly what it really is instead of a fake success. PNG files are larger than JFIF because PNG keeps every pixel losslessly.

What is a JFIF file?

JFIF (JPEG File Interchange Format) is the wrapper most .jpg photos are saved in; some downloads — especially from Windows and messaging apps — keep the .jfif extension instead. The image data is JPEG, so converting to PNG is lossless: the PNG will usually be bigger, because PNG keeps every pixel exactly.

How it works

Add your files and each one is checked by its actual bytes, decoded locally and re-encoded as PNG. Batch files are processed one by one and every file gets its own result line — converted, with its new size, or a plain explanation of why it could not be converted.
