Why convert AVIF to JPG?

  • Where JPG works best

    Photos, sharing, email, social media.

What is an AVIF file?

AV1 Image File Format

Developed By
Alliance for Open Media
Initial Release
2019
MIME Type
image/avif

The AVIF (AV1 Image File Format) is an open, royalty-free raster image container specified by the Alliance for Open Media (AOMedia) in ISO/IEC 23000-12. It encapsulates image sequences or still images compressed with the AV1 video codec within the HEIF (High Efficiency Image File Format) container structure. AVIF supports high dynamic range (HDR) utilizing Perceptual Quantizer (PQ) or Hybrid Log-Gamma (HLG) transfer functions, wide color gamut (WCG), and 4:2:0, 4:2:2, or 4:4:4 chroma subsampling, offering superior compression efficiency over JPEG and WebP.

How to open an AVIF file

Native support for AVIF is available in modern web browsers including Google Chrome (v85+), Mozilla Firefox (v93+), and Safari (v16+). For local viewing, Windows 10 and 11 require the installation of the free 'AV1 Video Extension' from the Microsoft Store to enable support in the Photos app and File Explorer. macOS 13 (Ventura) and iOS 16 provide system-level support. Graphics editors like GIMP, Paint.NET, and Adobe Photoshop (via plugin) can also decode and edit these files.

What is a JPG file?

Joint Photographic Experts Group

Developed By
Joint Photographic Experts Group
Initial Release
1992
MIME Type
image/jpeg

JPG is functionally identical to the JPEG format, differing only in the file extension length, a legacy constraint from the MS-DOS 8.3 filename limit (which allowed only three characters for extensions). It implements the same ISO/IEC 10918 standard, using lossy compression based on Discrete Cosine Transform (DCT) and Huffman coding to store photorealistic images. The file structure contains markers such as Start of Image (SOI) and End of Image (EOI) and supports color spaces like sRGB and CMYK, making it interchangeable with .jpeg files in all software contexts.

How to open a JPG file

As one of the most ubiquitous file types in computing, JPG files open natively on Windows, macOS, and Linux without external software. Default viewers like Microsoft Photos, Apple Preview, and Linux image viewers handle the format automatically. For editing or conversion, industry-standard tools including Adobe Photoshop, Paint.NET, and XnView provide extensive support. Web browsers universally render JPGs without plugins.
