Features

JFIF to PNG in one click

Drop in your JFIF files and download clean PNG images — batch several at once, each named to match its source.

Nothing is uploaded

The conversion runs entirely on a canvas in your browser, so private photos, screenshots and scans never leave your device.

No signup, no watermark

There's no account to create and no watermark stamped on the result — just the converted image, ready to use.

Lossless PNG output

PNG is a lossless format, so the converted image keeps every pixel of detail from the original.

How it works — in three simple steps

No signup, nothing to install — it all runs in your browser.

Step 01

Add your JFIF files

Drag your JFIF images onto the box, or click to browse and select them — one or many.

Step 02

Convert to PNG

Press Convert — each image is redrawn and re-encoded as PNG on your device.

Step 03

Download

Preview the results and download each PNG image, ready to use anywhere.

How it works

This converter turns JFIF images into PNG right in your browser. A .jfif file is simply a JPEG saved with a different extension — Windows sometimes produces them when you save an image from a browser — so converting it to PNG just re-wraps the same picture in the format you actually want. Load one or many files, and each is drawn onto an HTML canvas and re-encoded as PNG.

Nothing is uploaded — the whole conversion runs on your device using the browser's built-in image engine, so it's fast, private and works offline once the page has loaded. There's no signup, no watermark, and no limit beyond your device's memory.

Examples

Batch-convert a folder of JFIF images to PNG in one go — each downloads with the same name and a .png extension.
