Frequently Asked Questions
View sitemap →How does the tool reduce file size?
It can lower JPEG or WebP quality and, when needed, reduce oversized dimensions. PNG files can also be resized or converted to a more compact format.
Will the image look different?
Lossy compression can introduce small visual changes. The default balanced setting aims to reduce size without obvious quality loss for normal web use.
