Convert JFIF to AVIF

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.

AVIF (AV1 Image File Format) is a modern image format that offers superior compression and quality compared to JPEG, PNG, and WebP. Developed by the Alliance for Open Media, AVIF supports both lossy and lossless compression, HDR, wide color gamut, and transparency. Its efficient encoding reduces file sizes while maintaining excellent image quality, making it ideal for web content and digital media storage.

AVIF output is useful when you want small files, for example on a website, and the people or software receiving them support AVIF. It can be smaller than JPG at similar visual quality, but results vary by image and quality setting. Support is less universal than JPG, so check compatibility before sending AVIF files.

.AVIF image format fully supports transparency through an alpha channel, similar to PNG files. The format handles both binary (fully transparent or opaque) and variable transparency levels (partial opacity). When compressing images with transparency, AVIF maintains high quality while achieving better compression ratios compared to PNG and WebP formats. This makes AVIF an excellent choice for web graphics requiring transparency, such as logos, icons, and overlays.

Yes, some quality loss is possible. Framebird decodes the JFIF pixels and encodes a new AVIF file, and AVIF output can lose detail. The default quality setting is 90, and even quality 100 does not guarantee an identical image. Source metadata such as camera details is not copied to the new file. Keep your original JFIF in case you need it later.
