Turn AVIF images into widely compatible JPG files.
AVIF (AV1 Image File Format) is a royalty-free image format based on the AV1 video codec, with its first specification published in 2019 by the Alliance for Open Media. It currently offers some of the best compression efficiency of any mainstream image format, often producing noticeably smaller files than WebP at the same visual quality, while also supporting HDR color and transparency. Browser support has grown quickly since 2020, and AVIF is increasingly used on high-traffic websites to cut bandwidth and improve load times, though encoding and decoding remain more computationally demanding than older formats.
JPG is the most common file extension for images compressed with the JPEG standard, published in 1992. It applies lossy compression based on the discrete cosine transform, splitting images into small blocks and discarding visually insignificant detail to shrink file size. The compression level is adjustable: higher quality keeps more detail at a larger size, while lower quality trades visible artifacts for a much smaller file. JPG supports 24-bit true color and embeds Exif metadata such as camera model and capture date. Its biggest strength is universal compatibility — it is the native output of virtually every camera and phone, and opens in every browser, viewer, and operating system without exception.
Many editors and upload forms still don't recognize AVIF files.
No, AVIF decoding is handled natively by modern browsers.
Yes, this tool is completely free with no registration, no watermark, and no conversion limit.
No, the conversion happens locally in your browser using JavaScript. Your files are never uploaded to any external server.
There's no fixed limit enforced by the tool since everything runs in your browser rather than on a server.
For most everyday uses, the visual difference is negligible.
