Convert to AVIF with smart quality-size balance, real-time preview, batch processing
All image processing is done locally in your browser via WebAssembly, ensuring privacy. Conversion supports custom quality, smart compression, batch processing, real-time before/after comparison, and one-click download to optimize image loading and transfer efficiency.
Why convert to AVIF?
AVIF is a next-gen HD image format with stronger compression than JPG, PNG, and WebP, finer quality, more accurate color reproduction (supports HDR and 10-bit color depth), and transparency support. Smaller size saves storage and data, ideal for website acceleration, HD display, and premium asset storage.
What is AVIF?
AVIF (AV1 Image File Format) is a next-gen image format based on AV1 video coding. It supports HDR, wide color gamut, and transparency, using less space than PNG, JPG, and WebP at equivalent quality. Supported by all major browsers and mobile devices.
Why compress AVIF?
Native AVIF images have high quality but large file sizes, consuming storage and data, and slowing page and mini-program loading. Moderate compression produces nearly invisible differences while significantly reducing file size for faster opening and smoother uploads.
How does AVIF compression work?
AVIF is based on AV1 intra-frame coding. Lossy mode uses adaptive quantization and chroma subsampling to reduce visual redundancy. Lossless mode uses fully reversible coding to preserve all pixel information. Quantization parameters can be adjusted to control compression strength, achieving high ratios while maintaining quality, transparency, and color detail.
