How to Convert GIF to AVIF: Modern Compression for Classic Images

GIF is the oldest image format still in common use. It was built in 1987 for slow dial-up connections. Today, it's a relic that eats bandwidth and looks terrible compared to modern formats.

AVIF is the opposite. It's the most advanced image format available. Better compression. Better colors. Better everything.

Converting GIF to AVIF upgrades your images by decades of technology. Here's what you gain.

What's Wrong With GIF in 2026?

GIF has three major problems that no amount of optimization can fix.

256 colors. That's all GIF can handle. Modern screens display millions of colors. When a full-color image gets squeezed into 256 colors, it looks washed out. Gradients become visible steps. Skin tones get patchy. Photos look like they came from 1995.

Huge file sizes for animation. Animated GIFs store each frame as a separate image. A 5-second animation can easily hit 5-10 MB. The same animation as AVIF would be under 500 KB. GIF's "compression" is laughably inefficient by today's standards.

No partial transparency. GIF transparency is binary. A pixel is either fully visible or fully transparent. Nothing in between. This creates jagged, aliased edges around any transparent area. AVIF supports smooth alpha transparency with 256 levels of opacity.

AVIF fixes all three. 16.7 million+ colors. File sizes 90% smaller. Smooth transparency. It's not even close.

How Much Smaller Is AVIF Than GIF?

For static images (single-frame GIFs), the savings are dramatic:

GIF size	AVIF size	Savings
50 KB (simple icon)	5-10 KB	80-90%
200 KB (graphic)	15-30 KB	85-90%
500 KB (photo-like)	30-60 KB	88-94%

The savings are even bigger for complex images. GIF struggles with photos and detailed graphics because its 256-color limit forces wasteful dithering patterns. AVIF handles complex images natively with full color depth.

For animated GIFs, the potential savings are even more extreme, though ConvertIMG extracts a single frame rather than converting the full animation.

Does the Image Look Better After Conversion?

Often, yes. This is unusual for format conversions. Usually you expect some quality loss. But GIF-to-AVIF is special.

GIF's 256-color limit forces visible quality compromises. Dithering patterns. Color banding. Jagged transparency edges. These artifacts are part of the GIF, not the original content.

When you convert GIF to AVIF, the AVIF file faithfully captures whatever the GIF shows, including those artifacts. But if you start from a better source (the original PNG or JPG that was converted to GIF), the AVIF will look dramatically better because it isn't limited to 256 colors.

The key insight: if you have access to the original image before it was saved as GIF, convert from that instead. You'll get a much better AVIF.

How Do You Convert GIF to AVIF?

ConvertIMG converts GIF to AVIF in your browser. Drop your GIF file in, select AVIF, set the quality, and download.

The conversion runs on your device. No files uploaded. No accounts needed.

For quality settings:

• 80-85% for most images. This is the sweet spot. Quality is excellent and files are tiny.
• 70-75% for thumbnails and small graphics. Aggressive compression, still looks good at small sizes.
• 90%+ for images where you need maximum quality. Even at 90%, the AVIF is dramatically smaller than the GIF.

Since GIFs are already limited in quality (256 colors), you don't need high AVIF quality settings to match the original. Even 75% AVIF quality produces an image that's at least as good as the GIF source.

What Happens to Animated GIFs?

When you convert an animated GIF to AVIF with most tools, you get a still image of the first frame. The animation is removed.

If you specifically need animated AVIF, that's a more specialized workflow. AVIF does support animation (it's based on the AV1 video codec, after all), but most simple converters focus on still image conversion.

For static GIFs or when you just need a thumbnail from an animated GIF, the standard conversion works perfectly.

When Should You Use WebP Instead of AVIF?

Both modern formats are massive improvements over GIF. Choose based on your needs.

Choose AVIF when:

• You want the absolute smallest file sizes
• Your audience uses modern browsers (93%+ coverage)
• You can set up format fallbacks on your website
• Image quality at low file sizes is a priority

Choose WebP when:

• You need wider browser support (97%+ coverage)
• Your CMS or platform doesn't support AVIF yet
• You want faster encoding speed
• You need animated image support with broad compatibility

Either choice is a huge upgrade from GIF. You're going from a 1987 format to a 2020s format. The improvement is massive regardless of which you pick.
