JFIF to PNG converter

Turn .jfif images into PNG files that every app and upload form accepts. The browser converts them on this device, so your pictures are never uploaded.

A JFIF file is a JPEG with another name

JFIF stands for JPEG File Interchange Format, the standard layout of an ordinary JPEG image since 1992. A file ending in .jfif holds exactly the same kind of data as one ending in .jpg; only the label is different. The picture is not damaged and is not a rare format.

The label usually comes from Windows. When you save an image from a website, the site sends it as type image/jpeg, and Chrome or Edge on Windows asks Windows which extension goes with that type. Windows answers from a registry value, and on some PCs that value has been changed to .jfif. From then on every JPEG you save arrives as a .jfif, and upload forms and older apps that check the extension turn it away. What is a JFIF file explains the whole story and how to change the setting back.

Renaming it to .jpg also works

Because the file already is a JPEG, you do not strictly need a converter. Change the extension from .jfif to .jpg in File Explorer or Finder and it opens everywhere a JPG does, byte for byte unchanged. That is the right fix when you just want a JPG. Convert to PNG instead when you want a lossless copy to edit, when a form or app asks for PNG specifically, or when you have a folder of .jfif files and would rather drop them all on one page than rename each one.

How to convert JFIF to PNG

  1. Drop the .jfif files on this page, or choose them. There is no need to rename them first, and several at once is fine.
  2. Wait a moment. The browser reads each file as the JPEG it is and writes it out as a PNG.
  3. Save. Click Save PNG next to a file, or Save all to get them together in one ZIP. IMG_2041.jfif comes back as IMG_2041.png.

What changes, and what does not

The picture stays exactly as it is. PNG is lossless, so the PNG holds every pixel of the decoded JPEG at the same width and height, and later edits and saves add no further compression. It does not undo the JPEG compression that is already in the file either: a blocky or smudged .jfif gives an equally blocky PNG.

No transparency appears. A JPEG cannot hold a transparent background, so there is none to carry over, and changing the format does not create one. A white background stays white in the PNG. If what you actually want is the subject on a transparent background, the background has to be removed; see the last section below.

The file gets bigger. JPEG compression is built for photos and PNG keeps every pixel exactly, so a photo is often several times larger as a PNG. If you only need a file that opens, renaming to .jpg keeps it small. Metadata is not copied: any camera details, dates or location stored in the file stay behind.

Converting without uploading

Search for a JFIF converter and nearly every result uploads your picture to a server, re-encodes it there and sends it back. This page uses the image decoder and encoder built into your browser, so each file is converted on your own device and nothing is sent to getPNG or anyone else. Load the page, switch the browser to offline, and it still works. For a quick comparison of JPG, PNG and the iPhone's HEIC, HEIC vs JPG vs PNG sets out what each one is good for.

When you wanted a transparent PNG

Many people converting JFIF to PNG are really after a picture with no background: a product, a signature, a person for a slide. Each converted file has a Remove background button that opens it in getPNG's background remover, in the same browser and without uploading it. You can also go straight to the transparent background maker and drop the file there. Either way you get the subject on a real transparent PNG at full size. Have images from websites in other formats too? WebP to PNG and AVIF to PNG work the same way.

Questions

How do I convert JFIF to PNG?

Drop the .jfif files on this page, or choose them; there is no need to rename them first. Each one is converted in your browser and appears with a Save PNG button, or Save all to get them in one ZIP.

Is a JFIF file the same as a JPG?

Yes. JFIF is the standard layout of a JPEG file, and .jfif and .jpg are two extensions for the same kind of data. Renaming a .jfif to .jpg changes nothing inside the picture.

Should I rename the file or convert it?

Rename it to .jpg if you only need a file that opens or uploads; that keeps it small and unchanged. Convert it to PNG if you want a lossless copy to edit, or an app asks for PNG.

Will the PNG have a transparent background?

No. A JPEG cannot hold transparency, so the PNG has the same solid background the JFIF had. Use the Remove background button next to the converted file to cut the subject out onto a transparent PNG.

Does converting JFIF to PNG lose quality?

No. PNG is lossless, so every pixel is kept exactly. It cannot remove the JPEG compression already in the file, so the PNG looks the same as the JFIF, only larger.

Are my JFIF files uploaded?

No. The browser decodes each file and writes the PNG inside this tab, so nothing is sent to getPNG or anyone else. Once the page has loaded it works with the browser offline too.

Your files never leave this device

Most online converters upload every file to a server, convert it there and keep it for a while. Here your browser decodes and encodes the picture itself, so there is nowhere for the file to go. You can check it: load this page, switch the browser to offline, and convert a file. How to check a site is not uploading your photos.
