What is a JPEG (Joint Photographic Experts Group) file?

JPEG is an internationally accepted photographic image compression format formalized in 1992. By compressing raster pixel data through color subsampling and frequency quantization under the .jpeg extension, it has powered digital cameras and online media for over thirty years.

Why convert JPEG to AVIF?

Converting legacy JPEG files to AVIF delivers remarkable storage savings, frequently reducing file sizes by up to 50% without visible loss of sharpness. AVIF eliminates blocking artifacts in dark scenes, smooths out subtle color gradients, and supports wide color gamuts alongside High Dynamic Range (HDR) mastering.

What is an AVIF (AV1 Image File Format) file?

AVIF, or AV1 Image File Format, is a next-generation open image specification created by the Alliance for Open Media (AOMedia). Leveraging intra-frame compression from the AV1 video codec standard with the .avif extension, it delivers industry-leading data compression with support for 10-bit and 12-bit color depths and alpha transparency.

How to open and use an AVIF file?

AVIF files render natively in all mainstream web browsers including Google Chrome, Apple Safari, and Mozilla Firefox. Native photo viewers in modern operating systems such as Windows 11 and macOS Ventura display AVIF images without third-party software.

You can convert your JPEG photographs into high-efficiency AVIF images directly in your browser using our private, local converter.
