What Is AVIF & What Is JPG?

Two formats, two eras — here's what sets them apart.

AVIF

AV1 Image File Format

AVIF is a modern, royalty-free image format built on the AV1 codec. It delivers up to 50% smaller files than JPEG with HDR support, transparency, and wide color gamut — but only works in newer browsers.

Released 2019
Compression Lossy & Lossless (AV1)
Color Depth 8 / 10 / 12-bit HDR
Browser Support 93%+ Modern Browsers

Key Strengths

  • 50% smaller files at the same visual quality
  • HDR and wide color gamut support
  • Backed by Google, Apple, Mozilla & Netflix
JPG

Joint Photographic Experts Group

JPG is the world's most universal image format, standardized in 1992. It uses lossy DCT compression to keep photo files small and is natively supported by every browser, OS, camera, printer, and platform in existence.

Released September 1992
Compression Lossy (DCT-based)
Color Depth 8-bit SDR
Browser Support 100% Universal

Key Strengths

  • Works on every device and platform ever made
  • Ideal for photos, email, and printing
  • Accepted everywhere — social media, CMS, e-commerce

How to Use the AVIF to JPG Ubuntu Converter

This browser-based converter transforms AVIF images into JPG files directly on your Ubuntu desktop — no terminal commands, no apt package installation, and no codec libraries to configure. It works in Firefox, Chrome, and Chromium on Ubuntu 22.04, 24.04, and other Ubuntu-based distributions.

  1. Open this page in Firefox (pre-installed on Ubuntu), Google Chrome, or Chromium on your Ubuntu desktop.
  2. Drag your .avif file from the Nautilus file manager into the upload area, or click "Browse Files" to select it using the GTK file picker dialog.
  3. Click "Convert to JPG" — the conversion runs entirely inside your browser, independent of any system libraries like libheif, gdk-pixbuf, or ImageMagick.
  4. Preview the converted image to verify the output quality and compare file sizes.
  5. Click "Download JPG" to save the file to your ~/Downloads directory or any location you choose in the file manager.

No sudo commands, no PPA repositories, and no dependency chains to manage. The converter works out of the box on a fresh Ubuntu installation with just a modern browser.

How the AVIF to JPG Ubuntu Converter Works

When you load an AVIF file in your Ubuntu browser, the converter uses the browser's built-in AV1 decoder rather than system-level codec libraries. This means it works without installing libavif, libheif, or any other Linux packages.

  • File Validation: The converter checks that your file has a valid .avif extension or AVIF MIME type and is under 20 MB before processing. This validation runs in JavaScript, independent of Linux file-type detection.
  • Browser-Level AV1 Decoding: Firefox and Chrome on Ubuntu ship with their own bundled AV1 decoders (dav1d in Firefox, libgav1 in Chrome). The converter uses these browser-internal decoders rather than relying on system packages like libavif or gdk-pixbuf-loader-avif.
  • Canvas Pixel Processing: The decoded RGB bitmap is rendered onto an HTML5 Canvas at the full original resolution. Transparent areas are filled with white because the JPG format does not support alpha channels. This uses GPU-accelerated rendering if available via Mesa/Vulkan drivers.
  • JPEG Encoding: The Canvas API encodes the bitmap into JPEG at 92% quality. This is handled entirely by the browser's media stack, not by system JPEG libraries like libjpeg-turbo (though the browser may use its own bundled copy internally).
  • XDG Download: The resulting JPG blob is served through an in-memory URL. Clicking Download triggers the browser's save dialog, which follows your XDG user directories configuration to suggest the correct Downloads location.
AVIF File → Browser AV1 Decoder (dav1d/libgav1) → Canvas Bitmap → Browser JPEG Encoder (92%) → XDG Downloads

Your images are processed inside the browser's sandboxed environment. No data leaves your Ubuntu machine, and no Linux system permissions beyond basic file access are required.

AVIF to JPG Ubuntu Converter FAQs and Common Questions

Can Ubuntu open AVIF files natively?

Ubuntu 22.04 LTS and later include AVIF support through the libheif and gdk-pixbuf-loader-avif packages, enabling AVIF viewing in Eye of GNOME (EOG) and Nautilus thumbnails. However, many Ubuntu users do not have these packages installed by default. Converting to JPG bypasses any library dependencies.

How do I convert AVIF to JPG on Ubuntu without using the terminal?

Open this page in Firefox, Chrome, or Chromium on your Ubuntu desktop. Drag your AVIF file into the converter or click Browse Files to select it from the file manager. Click Convert to JPG and download the result — no apt-get, snap, or flatpak commands needed.

Does this work on Ubuntu-based distributions like Linux Mint and Pop!_OS?

Yes. Because the conversion runs inside your web browser, it works identically on Ubuntu, Linux Mint, Pop!_OS, elementary OS, Zorin OS, and any other Debian or Ubuntu-based distribution.

Can I convert AVIF to JPG using the Ubuntu command line instead?

You can use tools like ImageMagick (magick input.avif output.jpg) or libheif's heif-convert command from the terminal. However, this browser-based converter requires zero package installation and works instantly without configuring codec libraries.

Which Ubuntu browsers support AVIF decoding?

Firefox (v93+, included by default on Ubuntu), Google Chrome (v85+), Chromium (v85+), and Brave all support AVIF on Ubuntu. The Firefox snap package included in Ubuntu 22.04+ handles AVIF natively.

Will the converter work on Ubuntu Server or a headless setup?

This converter requires a graphical browser to process images via the HTML5 Canvas API. On headless Ubuntu Server, use command-line tools like ImageMagick or libheif instead. For Ubuntu Desktop with a GUI, this converter works perfectly.
