Frequently Asked Questions
Common Questions & Answers
Clear answers about image formatting, compression standards, and privacy.
How does image compression work without losing quality?
Our compression algorithms strip redundant metadata (EXIF, camera profiles) and apply perceptual quantization, discarding color data that the human eye cannot perceive while preserving sharp edges and fine details.
What happens if I specify a Max File Size (KB)?
The optimizer automatically performs progressive quality downstepping, iteratively finding the highest visual quality setting that fits strictly underneath your KB constraint.
Which format achieves the highest compression ratio?
WebP typically delivers 25-35% smaller file sizes than standard JPEG at equivalent visual quality. For modern websites, converting to WebP provides maximum speed savings.
