Why use ConvertWiki?
Optimize PNG screenshots and graphics
PNG is lossless and supports transparency, which makes it ideal for screenshots, interface graphics, logos, and simple illustrations. The tradeoff is file size, especially when images contain many colors.
This compressor keeps the PNG format and transparency while applying stronger PNG optimization. For photos without transparency, JPG or WebP may create a smaller file.
