Created in 1996 to sidestep GIF's patent problems. Lossless — save it a hundred times and nothing changes — and it supports transparency. Right for screenshots, logos, icons and any image with text in it.
| PNG → JPG | Transparency becomes white or black, and a little quality is traded for a much smaller file. No loss to speak of on a photo; text and lines get fuzzy. |
| PNG → WEBP | In lossless mode, nothing lost — just smaller. |
| PNG → SVG | Not really possible — turning pixels into vectors is tracing, and you get a different picture. |
| PNG → ICO | Scaled down into several sizes. |
一句话 Photos as jpg, screenshots and logos as png. That one rule removes most size and quality problems.

不需要。在浏览器中直接使用。如果需要,也提供 Windows 安装版。
可以。我们把各引擎能处理的组合合并成一张图,未直接支持的组合会经由中间格式自动衔接,并选择损失最小的路径。
