Convert JFIF to JPEG

JFIF (JPEG File Interchange Format) is a standardized image file format that stores digital photos and graphics using lossy compression. Created by C-Cube Microsystems, it's essentially a more detailed specification of the JPEG format. JFIF files maintain good image quality while reducing file size, making them ideal for web use and digital sharing, though they may lose some quality during compression.

JPEG (Joint Photographic Experts Group) is a widely-used digital image format that efficiently compresses photographs and complex graphics. It reduces file size by selectively discarding visual data that human eyes are less likely to notice. While JPEG compression is "lossy," meaning some quality is sacrificed, it maintains good visual appearance at reasonable file sizes, making it ideal for web images and photo sharing.

JPEG files do not support transparency. The format only handles fully opaque pixels and cannot display partially transparent or completely transparent areas. When saving an image with transparent elements as a JPEG, transparent areas typically convert to solid white or black backgrounds. For images requiring transparency, use PNG or WebP formats instead, as these support alpha channels for transparent and semi-transparent elements.

Some quality loss is possible. JFIF is already a JPEG container, but Framebird does not just rename or copy it. It decodes the pixels and re-encodes a new JPEG file, which can lose detail. The default quality setting is 90, and even quality 100 does not guarantee an identical image. Source metadata is not copied, so keep your original JFIF file.
