关于这种格式

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.

能承载的内容

  • Lossless image data
  • Transparent (alpha) background
  • 16 million colours or a palette

无法承载的内容

  • Animation (APNG is separate)
  • CMYK
  • EXIF shooting data — usually absent

转换为其他格式时

PNG → JPGTransparency 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 → WEBPIn lossless mode, nothing lost — just smaller.
PNG → SVGNot really possible — turning pixels into vectors is tracing, and you get a different picture.
PNG → ICOScaled down into several sizes.

打不开的时候

  • Another format wearing a .png extension
  • A 16-bit png that an old program cannot read

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。
