FAQ
Does resizing an image reduce file size?
Yes — reducing the pixel dimensions of an image almost always reduces its file size, since fewer pixels means less data to store. You can also adjust the JPG/WebP quality slider to further reduce file size with minimal visible quality loss.
What is the best image format for the web?
WebP is the modern standard — it's smaller than both JPG and PNG at equivalent quality. Use WebP for all web images when browser support allows. Fall back to JPG for photographs and PNG for images requiring transparency.
