Frequently Asked Questions
What is a compression ratio?
The compression ratio is the relationship between the size of the original uncompressed image and the size of the compressed version. A higher ratio means a smaller file size, which is better for web performance.
Which format has the best compression?
Generally, AVIF and WebP offer significantly better compression than traditional formats like JPG or PNG. AVIF often provides the smallest file sizes at comparable quality levels, though WebP has broader compatibility.
