What's the difference between GIF and AVIF?

GIF is a 1987 format that survives in 2026 only because of animation. AVIF is the newest mainstream image format, built on top of the AV1 video codec.

Will I lose quality converting from GIF to AVIF?

Yes — AVIF discards some image detail in exchange for much smaller files. At quality 80 or above the difference is usually invisible to the eye. For maximum quality, use quality 90+. For maximum compression, drop to quality 70 (still acceptable for most photos).

What quality should I pick?

For AVIF, 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 GIF?

GIF is a 1987 format that survives in 2026 only because of animation. Where it falls down: still images (use PNG, JPG, or WebP); long or high-quality animations (use WebP or MP4 — much smaller). AVIF addresses that for most workflows.

When is AVIF the right format?

AVIF is a good choice for: hero images and other content where every byte matters; build-time image pipelines that can absorb the encoding cost; photos with smooth gradients (the AV1 codec excels here). It is a poor choice when on-the-fly conversion where the user is waiting (slow encode).

Anything surprising about GIF or AVIF?

GIF's 256-color palette means photos look posterized. And on the AVIF side: AVIF encoding is single-threaded by default — large images can take 5–10 seconds in browser.

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 GIF to AVIF

AVIF files are typically much smaller than GIF at equivalent quality — usually the main reason to make this conversion. Smaller files mean faster page loads, smaller email attachments, and less storage. Only the first frame is converted; animation is not preserved.
