AVIF to JPEG via CLI

Decode an AVIF still with ffmpeg and write a JPEG.

Packages to install

Only ffmpeg is required. AV1 stills in AVIF decode to a single JPEG frame.

ffmpeg

sudo apt-get update
sudo apt-get install -y ffmpeg

How to run the command

ffmpeg -i photo.avif -frames:v 1 -update 1 -q:v 2 photo.jpeg. -q:v 2 keeps JPEG quality high; raise it to shrink the file.

ffmpeg -y -i photo.avif -frames:v 1 -update 1 -q:v 2 photo.jpeg

Dockerfile example

Build a minimal Ubuntu image with the required packages and run the conversion inside the container.

FROM ubuntu:24.04

RUN apt-get update && \
    apt-get install -y --no-install-recommends \
        ffmpeg && \
    rm -rf /var/lib/apt/lists/*

WORKDIR /work

docker build -t avif-to-jpeg .
docker run --rm -v "$PWD:/work" -w /work avif-to-jpeg \
  ffmpeg -y -i photo.avif -frames:v 1 -update 1 -q:v 2 photo.jpeg

Example commands

Run these locally after installing the packages, or inside the container from the Dockerfile.

ffmpeg -y -i photo.avif -frames:v 1 -update 1 -q:v 2 photo.jpeg

ffmpeg -y -i screenshot.avif -frames:v 1 -update 1 -q:v 2 screenshot.jpg
