Convert AVIF to JPG on Linux — Free Browser and CLI Methods

Linux users have two good options for AVIF to JPG conversion: the browser-based converter (zero dependencies, works immediately) or command-line tools like ImageMagick or ffmpeg (batch-friendly, scriptable). This covers both approaches.

Method 1: Browser Converter on Linux (No Dependencies)

Chrome and Firefox on Linux have supported AVIF since 2020. Open the free AVIF to JPG converter in your browser:

1. Navigate to the converter
2. Drop your AVIF file(s) in
3. Convert and download

This works on any Linux distro — Ubuntu, Fedora, Arch, Debian — as long as you have Chrome, Chromium, or Firefox installed (which covers virtually all desktop Linux setups). No extra packages, no sudo.

Method 2: ImageMagick (Command Line)

ImageMagick supports AVIF natively on versions 7.1.0+ with libavif. Check your version: magick --version

Single file conversion:

magick input.avif -quality 90 output.jpg

Batch conversion (all AVIF in current directory):

for f in *.avif; do magick "$f" -quality 90 "${f%.avif}.jpg"; done

Install on Ubuntu/Debian: sudo apt install imagemagick
Install on Fedora: sudo dnf install imagemagick
Install on Arch: sudo pacman -S imagemagick

Note: Some distro package repos have older ImageMagick versions that may lack AVIF support. If conversion fails, check that your version is 7.1+.

Method 3: ffmpeg for AVIF to JPG

ffmpeg can handle still image format conversion:

ffmpeg -i input.avif output.jpg

For quality control:

ffmpeg -i input.avif -q:v 2 output.jpg

(Lower -q:v = higher quality. Range 1-31; 2 is near-lossless for JPEG output.)

Batch with ffmpeg:

for f in *.avif; do ffmpeg -i "$f" "${f%.avif}.jpg"; done

Install: sudo apt install ffmpeg or equivalent for your distro.

Browser vs ImageMagick vs ffmpeg: When to Use Each

Situation	Recommended Method
Quick single file, no packages available	Browser converter
Batch conversion in a script	ImageMagick or ffmpeg
Already have ImageMagick installed	ImageMagick
Server without display (headless)	ImageMagick or ffmpeg
Need to process files from a web download	Browser converter

Frequently Asked Questions

Does GIMP on Linux support AVIF?

GIMP 2.10.34+ supports AVIF on Linux with the AVIF plugin. Some distro packages include it; others require manual installation. ImageMagick is usually simpler for batch conversions.

Why does ImageMagick say "no decode delegate for AVIF"?

Your ImageMagick version is too old or was compiled without libavif. Try updating: sudo apt update && sudo apt upgrade imagemagick. If the repo version is still old, build from source or use the browser converter.

Can I use the browser converter on a Linux server?

Not directly — servers typically don't have a browser. For server-side conversion, use ImageMagick or ffmpeg in a script or install libavif and use avifenc/avifdec (the reference implementation).
