A .jfif is a JPEG with an unusual extension; some computers save pictures from email or a web page that way. Renaming it to .jpg already works and changes nothing inside. If you would rather not rename it, open it here: the result card writes a .jpg at quality 92 and shows the new size first.

1. Click Choose a JFIF, or drop the file on the page. It opens like any JPEG. Several files chosen together come back as one zip.
2. In the card JPG is already selected; for the 1200 × 900 sample the line reads 168 KB → 186 KB · JPG · 1200 × 900. The picture is written again at quality 92. If you need the file byte for byte, rename it instead.
3. Click Download JPG. The name stays, the extension becomes .jpg. For a quality other than 92, click More options... to open Export As.

Can I just rename .jfif to .jpg?

Yes, and nothing is lost, camera details included. Use this page when you can't rename the file, have a lot of them, or want to crop or compress on the way.

Can I get a PNG instead?

Yes. Pick PNG in the card. It is lossless, so it comes out much larger: the sample goes from 168 KB to 1.5 MB.

Will the quality drop?

The card writes the JPG again at quality 92, which is a second round of JPEG compression. For the original bytes, rename the file; for a lossless copy, pick PNG in the card.

The site still rejects the file.

Check its size limit. Click Compress under Next and set a cap such as 200 KB.

What are the limits?

Up to 100 million pixels a file. EXIF (camera, date, location) is not carried over; if you need it, rename the file instead. The conversion runs in your browser; nothing is uploaded.
