About JPEG
JPEG is the standard lossy image format, named after the Joint Photographic Experts Group that published it in 1992. It shrinks photos to a fraction of their raw size by discarding fine detail.
Photos from cameras and phones, images on the web and email attachments; every device and app opens it.
JPEG has no transparency, stores 8 bits per colour channel, and loses a little more quality every time it is saved again.
Convert JPEG to AVIF online free, no account required — AVIF is a modern image format based on the AV1 video codec.
Change JPEG to AVIF without losing quality — convert JPEG to AVIF free in your browser.
Why does my photo get worse every time I edit and save it as JPG? Each save re-compresses the image and piles new artifacts on the old ones — working from a lossless original and exporting once to JPG avoids the buildup.
About AVIF
AVIF is an image format based on the AV1 video codec, published by the Alliance for Open Media in 2019. It supports lossy and lossless compression, transparency, HDR and wide colour.
Modern websites, which use it for images smaller than WebP or JPEG at similar quality.
Encoding AVIF is slow, and older software and operating systems may not open it.
Why convert images to AVIF? It is the smallest format today’s browsers accept, often half the size of JPG, with HDR and wide-colour support on top.
What changes when you convert JPEG to AVIF
- The JPEG picture is re-encoded as AVIF at the default quality settings, so it looks close to the original but is not bit-identical.
Settings you can change
Before you convert JPEG to AVIF, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.
