Batch Convert GIF to AVIF Online — Preserve Animations

Yes! Animated GIFs are converted to animated AVIF, preserving all frames. This converter intelligently handles both types:

• Animated GIFs → Animated AVIF (all frames preserved)
• Static GIFs → Static AVIF (single frame, optimized compression)

Benefits of animated AVIF:

• Smallest files available: Animated AVIF is typically 50-90% smaller than GIF
• Best quality: AV1 codec provides superior compression vs GIF's 256-color palette
• Next-gen format: Growing browser support (Chrome, Firefox, Safari, Edge)
• Perfect for: Animated graphics, UI animations, product demos, and web content

Note: Due to current encoder limitations, individual frame timing may not be preserved. For perfect timing preservation, consider GIF to WebP.

We support animated GIFs up to 720 frames (~30 seconds at 24fps). AVIF uses the AV1 codec which delivers exceptional compression but is computationally expensive to encode—especially for animated content.

Maximum duration by frame rate:

• 10 fps: Up to 72 seconds
• 15 fps: Up to 48 seconds
• 24 fps: Up to 30 seconds
• 30 fps: Up to 24 seconds

Tip: For longer animations, consider GIF to WebP which encodes much faster.

AVIF offers the best compression available today. For animated GIFs, AVIF is the cutting-edge choice:

• Smallest files: Animated AVIF is typically 30-50% smaller than animated WebP and 50-90% smaller than GIF
• AV1 codec: Uses the same codec as Netflix and YouTube for maximum efficiency
• Better quality: Superior compression preserves more detail at lower file sizes
• Growing support: Chrome, Firefox, Safari, and Edge all support AVIF

For the absolute best compression with excellent quality, GIF→AVIF is the top choice.

Lossless by default—we preserve perfect quality. GIF is already a lossless format (within its 256-color palette), so we use lossless AVIF to maintain that quality:

• No quality loss: Every pixel is preserved exactly
• Excellent compression: Lossless AVIF produces dramatically smaller files than GIF
• Full transparency: Alpha channel preserved with all 256 levels

Even in lossless mode, AVIF's AV1 codec delivers exceptional compression that beats both GIF and PNG.

Expect 40-90% smaller files depending on the content. Results vary by image type:

• Animated GIFs: 50-90% smaller (huge savings from AV1 codec)
• Simple static graphics: 70-90% smaller (solid colors, simple shapes)
• Complex static images: 40-70% smaller (photos, detailed graphics)
• Already optimized GIFs: 40-60% smaller

AVIF's AV1 compression is particularly effective on all content types, making this conversion one of the best ways to reduce file sizes and speed up your website.

Yes, and it gets much better. AVIF has superior transparency support:

• GIF transparency: Binary (on/off) - pixels are either 100% transparent or 100% opaque
• AVIF transparency: Full alpha channel with 256 levels of transparency

Your transparent areas are preserved, often with smoother edges than the original GIF. This makes GIF→AVIF ideal for:

• Logos and icons with transparent backgrounds
• Graphics that overlay other content
• UI elements and buttons

Animated AVIFs loop infinitely by default. Due to current AVIF encoder limitations:

• Loop behavior: All animated AVIFs loop infinitely (finite loop counts are not preserved)
• Frame timing: Individual frame delays may not be preserved; the animation uses a uniform frame rate
• Frame order: All frames are converted in original sequence

Note: These are limitations of the current libheif AVIF encoder, not our service. For full animation metadata preservation, consider GIF to WebP which preserves loop count and frame timing perfectly.

AVIF uses the AV1 codec, which prioritizes compression efficiency over encoding speed. This is an intentional tradeoff:

• Encoding time: AVIF takes 2-3× longer than WebP (especially for animated content)
• Decode time: AVIF decodes 2-3× slower than WebP in browsers
• File size: AVIF is 20-40% smaller than WebP at equivalent quality
• Worth the wait: For animated content, the superior compression often justifies the extra processing time

For server-side batch conversions like ours, the extra encoding time is usually acceptable since you convert once and serve forever. The bandwidth savings compound over every user who views the image.
