What's the difference between AVIF and JPEG XL?

AVIF is the newest mainstream image format, built on top of the AV1 video codec. JPEG XL is a modern, royalty-free image format with state-of-the-art compression.

What quality should I pick?

For JPEG XL, quality 75-85 is the sweet spot — small files with no visible difference from the original. Lower than 60 starts to show artifacts. Higher than 90 mostly just makes the file bigger.

Why convert away from AVIF?

AVIF is the newest mainstream image format, built on top of the AV1 video codec. Where it falls down: on-the-fly conversion where the user is waiting (slow encode); older devices and software pipelines; anything that needs to round-trip through editing tools (limited support). JPEG XL addresses that for most workflows.

When is JPEG XL the right format?

JPEG XL is a good choice for: high-quality archival images at small sizes; losslessly shrinking existing JPEG libraries; workflows where you control decoding (apps, pipelines). It is a poor choice when broad web delivery today (inconsistent browser support).

Anything surprising about AVIF or JPEG XL?

AVIF encoding is single-threaded by default — large images can take 5–10 seconds in browser. And on the JPEG XL side: JPEG XL can recompress a JPEG losslessly ~20% smaller and restore the exact original.

Does this work on mobile?

Yes. The drop zone falls back to your phone's file picker, and conversions run on-device just like desktop. Large files may be slower on mobile due to CPU and memory constraints, but the workflow is identical.

What's the maximum file size?

No hard limit — the browser handles it. Files under 50MB convert in a few seconds. Larger files work but may take longer as the browser allocates memory. If you hit issues, batch in smaller groups.

Overview

Why convert AVIF to JPEG XL

AVIF has limited compatibility — supported in chrome, firefox, safari 16+, and edge. pre-2022 devices may not decode it. JPEG XL is broadly supported, which is the most common reason to convert. AVIF is already efficiently compressed, so the size difference may be modest.

AVIF vs JPEG XL: what actually differs

AVIF compared with JPEG XL across encoding, fidelity, file size and support.
Attribute	AVIF	JPEG XL
Compression	Lossy	Lossy or lossless
Transparency	Yes	Yes
Animation	Yes	Yes
Typical file size	Small	Small
Browser support	Supported in Chrome, Firefox, Safari 16+, and Edge. Pre-2022 devices may not decode it.	Limited — Safari 17+ supports it; Chrome and Firefox are still behind flags or pending. Great for archival and apps that control their own decoder.
