Frequently Asked Questions
Image scale mechanics.
Does resizing affect image quality?
Scaling down generally preserves sharpness but discards detail. Scaling up from a small source will result in pixelation or blurriness because new pixel colors are interpolated. Selecting WebP or PNG output helps minimize compression artifacts.
Why use WebP output format?
WebP offers superior lossless and lossy compression compared to JPEG and PNG. Converting your scaled images to WebP can reduce file sizes by up to 30-50% while maintaining equivalent visual fidelity.
