How do I convert and save a JFIF image as JPG?

Select Choose JFIF images, pick your files, adjust JPEG quality if needed, then select Convert to JPG. Your browser downloads each converted image separately. Files must be no larger than 50 MB each, and images must fit the 40 megapixel canvas limit. A browser may ask permission for multiple downloads.

Can I convert multiple JFIF files at once?

Yes. Select or drag up to 50 files at once. They are converted one at a time and downloaded individually, without a ZIP archive.

Can I use this conversion software on a phone, Mac or Windows computer?

This free browser tool needs no installation. Use a current browser on Android, iPhone, Mac or Windows and choose local files through its file picker. It is browser software, rather than a downloadable desktop program or mobile app.

Is JFIF the same as JPG, and can I just rename it?

JFIF is a common interchange format for JPEG images. A compatible viewer may open the same file after its extension is changed to .jpg. This converter instead decodes and re-encodes the pixels, so it does not perform a lossless filename-only change.

How do I choose between smaller files and higher quality?

Lower JPEG quality usually reduces the output size but can discard more detail. Higher quality retains more detail but does not restore detail already lost. Re-encoding can change pixels even at 100%, and no specific output size is guaranteed.

What happens to transparency and metadata?

JPEG cannot retain transparency. Any transparent pixels are filled with the chosen background colour. The tool draws pixels onto a canvas and does not copy source EXIF metadata into the output.

The conversion redraws each selected image in this browser and encodes a JPEG at the quality you choose. JPEG is lossy and cannot keep transparency; the original file is never uploaded or overwritten.
