Compress AVIF Online

1. Upload one or more AVIF files (up to 50 MB total).
2. Choose a compression level.
3. Click 'Compress AVIF' — finishes in 3-5 seconds per image (AV1 encoding is slower).
4. Download compressed files individually, or grab all as a ZIP.

AVIF is already the most efficient mainstream image format — typically 50% smaller than JPG. Compression gains are therefore modest (20-40%) and usually only matter when strict size limits must be met.

AVIF is 50% smaller than JPG at the same quality — the most efficient mainstream format. Because AVIF is already highly optimized, further compression has limited benefit: reducing quality from 100% to 85-90% typically produces 20-40% smaller files with no visible difference. Compressing AVIF matters mostly when a strict size limit (e.g. 200 KB) must be met, or when serving a large number of AVIF files.

The compressor decodes the AVIF image and re-encodes it using libavif at a lower quality setting. Quality 85-90% is visually indistinguishable from 100% while being 20-40% smaller. Transparency is preserved.

• Meeting strict upload size limits for AVIF-optimized sites.
• Reducing bandwidth costs for AVIF-heavy CDNs.
• Preparing AVIF assets for mobile delivery.
• Optimizing hero images for Core Web Vitals.
• Reducing AVIF file size for email attachments.
• Preparing AVIF assets for platforms with size caps.
• Final optimization pass before publishing to production.

AVIF at 85% quality is visually indistinguishable from 100% on modern screens. Below 75% quality, artifacts start showing in detailed areas. Because AVIF is already the most efficient format, the compression gain is smaller than for JPG or PNG.

• AVIF is already efficient — compression gain is modest (20-40%).
• AV1 encoding is slower than other codecs (3-5 seconds per image).
• Below 75% quality, visible artifacts may appear.
• Animated AVIF is compressed using the first frame only.
• Very old software may not support AVIF.

• Output AVIF opens in every browser since 2020.
• Native support in Windows 11, macOS Big Sur+, iOS 16+, Android 12+.
• Supported by WordPress via plugin, Ghost, Next.js.
• Native import in Photoshop 23.2+, GIMP 2.10.22+, Affinity Photo 2+.
• Ideal for modern CDN delivery.

• 85% quality is the sweet spot for AVIF — 25-35% smaller with no visible change.
• AVIF compression is slower than JPG or PNG — expect 3-5 seconds per image.
• Keep the original if the image is critical.
• For maximum size reduction, consider converting to a lower-quality AVIF or JPG.
• Batch-compress up to 50 MB at once.

AVIF compression is slow

AV1 encoding is CPU-intensive. Typical compression is 3-5 seconds per image. This is the trade-off for the most efficient format.

AVIF is barely smaller after compression

AVIF is already efficient — savings are 20-40%, lower than for JPG. Try 'Maximum' level or use a lower-quality setting.

AVIF looks blurry after compression

The compression level was too aggressive. Use 85-90% quality instead.
