Frequently Asked Questions

Your AVIF image is decoded, then re-encoded at a lower quality setting using the AVIF encoder. This can significantly reduce file size while maintaining acceptable visual quality.

For web images, a quality of 40-60 offers an excellent balance of file size and visual quality. For high-quality images, use 70-80. The preview lets you compare before downloading.

AVIF supports lossless compression, but for significant size reduction, lossy compression is needed. Use the quality slider and preview to find a setting where quality loss is imperceptible.
