    How to use

    1. Choose JFIF files or drop them into the box.
    2. Convert: each file keeps its original JPEG data and is saved with the .jpg extension.
    3. Review each image, then download it individually or as a ZIP.

    Example

    image.jfif → image.jpg
Image data: unchanged (no re-encoding)
File size: identical to the original

    Details and limitations

    Files are processed in your browser without uploading to a conversion server. No account or watermark.

    Up to 20 files per batch, 20 MB and 40 megapixels each. Images are processed one at a time to limit memory use.

    JFIF is the JPEG file format; .jfif is only a different file extension. This page copies the bytes unchanged and names the copy .jpg, so quality, size and embedded metadata stay exactly as they were.

    FAQ

    Can I convert several JFIF images at once?

    Select up to 20 static images and convert them together. Save successful conversions in one ZIP; a failed file does not discard the others. Repeated filenames receive a numbered suffix.

    What is a JFIF file, and does converting lose quality?

    A .jfif file is an ordinary JPEG image saved with a less common extension (Windows and some browsers use it when saving images). Because the format is the same, the conversion only renames the file to .jpg — nothing is re-compressed and no quality is lost.

    Is it free and safe? Are my images uploaded?

    It is free and needs no account. Files are processed in your browser and are not uploaded. Because the JPEG data is copied unchanged, metadata already in the file (such as camera details or GPS location) is kept.

    Does it work on Windows, Mac, iPhone and Android?

    Yes, in a current browser on each; no app or browser extension is needed. Phones have tighter memory limits, so a very large image may fail there — convert it on a computer instead.

    Can I convert a whole folder?

    In the file dialog, press Ctrl+A (⌘+A on Mac) to select every image in a folder, then convert up to 20 at a time. Dragging a folder itself is not supported; split larger sets into batches of 20.
