Got a .jfif file that won't upload or open where you need it? Convert it to PNG to get a widely accepted, lossless file that you can edit and save again and again without it degrading further.
or click to upload. JPG, PNG, WebP, AVIF, HEIC and JFIF supported
Your image is converted in your browser and never uploaded.
PNG stores every pixel exactly, so the conversion adds no new compression damage and repeated saves never wear the image down.
PNG is the safer format for images you'll crop, annotate or edit further, especially screenshots and graphics with text.
Unlike the .jfif extension, PNG is recognized by every image viewer, editor, website and upload form.
Your JFIF is converted by your own browser. It is never uploaded to a server, and nothing is kept after you close the tab.
No account, no email, no daily limit, and nothing stamped on your image. Convert as many JFIF files as you like, one after another.
Converts JFIF to PNG in any current browser on Windows, Mac, Linux, iPhone or Android. There is nothing to download or install.
A JFIF file is really a JPEG with an unusual extension, often produced when Windows saves an image from a web browser. The picture is fine, but software and upload forms that go by the file name may refuse it.
Converting to PNG gives you a universally accepted file that is lossless from here on. The converter decodes the JFIF in your browser and writes every pixel into a PNG at the same size, with no further compression loss.
Drop your .jfif file onto the converter, choose it from your device, or paste it with Ctrl+V or Cmd+V.
PNG is already selected. PNG is lossless, so there's no quality setting to worry about.
Compare the preview and file size with the original, then download your PNG.
Converting is often only the first step. These tools work the same way, in your browser, and accept the file you just made.

.jfif, .jfi, .jif
JFIF is the standard, published in 1992, that describes how JPEG-compressed image data is packed into a file. Most ordinary .jpg files follow it internally, so a .jfif file is a JPEG in everything but name.
The extension usually appears because Windows saved an image from a browser with .jfif instead of .jpg. The picture inside is fine, but some upload forms and apps only check the extension and reject the file.

.png
PNG was created in 1996 as an open replacement for GIF. It is lossless: every pixel is stored exactly, so saving a PNG again never wears the image down.
It supports full transparency, including soft, partly see-through edges, which makes it the usual choice for logos, icons, screenshots and cut-out product images. The trade-off is size: a photo saved as PNG is several times larger than the same photo as a JPG.
| JFIF | PNG | |
|---|---|---|
| Introduced | 1992 | 1996 |
| Compression | Lossy (JPEG) | Lossless |
| Transparency | No | Yes, including soft edges |
| Size of a photo | Small | Large |
| Opens in | Most viewers; some forms reject the name | Almost everything |
| Good for | Nothing a .jpg doesn't do better | Logos, screenshots, graphics, editing |
Every time a JPEG is edited and saved, it's compressed again. As a PNG, further edits are saved without any additional loss.
If the image is a screenshot, chart or diagram you'll keep editing, PNG keeps sharp edges and small text clean from here on.
Forms that reject .jfif accept PNG, and so do editors and design tools that don't recognize the JFIF extension.
PNG is the standard hand-off format for presentations, documents and design tools, and it supports transparency if you add it later.
JFIF stands for JPEG File Interchange Format. It's a standard way of storing JPEG image data, and most .jpg files use it internally. A .jfif file is simply a JPEG with a different extension, often created when Windows saves an image from a browser.
No. Any detail the JPEG compression removed is gone. What PNG does is prevent further loss: the image looks exactly as it does now, and it stays that way no matter how many times you edit and save it.
JPEG discards detail to keep files small, while PNG stores every pixel losslessly. For photos, that often makes the PNG several times larger. If size matters, convert to JPG or WebP instead.
A JFIF can't contain transparency, so the PNG starts fully opaque. PNG does support transparency, though, so you can remove the background in an editor afterwards and save it without losing quality.
No. The PNG is written from the image’s pixels alone, so EXIF details such as the camera model, the date taken and GPS location are not copied over. That makes the converted file safer to share, but keep your original if you need that information.
No. The conversion runs entirely in your browser: your JFIF is opened, turned into a PNG and saved on your own device. Nothing is sent anywhere, and nothing is kept once you close the tab.
Each one opens the same converter with its format already chosen, plus a guide to both formats.
