PNG - Advanced options for image conversion

If you only want to convert the image format, there is no need to modify the conversion options, just keep the default.


  • Lossless

    The most common PNG format provides the highest image quality and preserves all the details of the image.


  • Compression

    Lossy compression of png images

    1. 256 C

      Compress PNG by limiting the number of colors in PNG and controlling the number of colors in PNG within 256.

    2. 256 6000

      Compress PNG by limiting the number of colors in PNG and controlling the number of colors in PNG within 6000.

    3. Tinypng Recommend

      Provides a compression algorithm similar to Tinypng, which has a very good compression effect, providing natural color gradients and supporting transparent/translucent features of the alpha channel. After compression, the image quality will be slightly reduced (almost unrecognizable to the naked eye), and the file size of the image will be greatly reduced, which can reduce the size of the png file by about 50-80%.


      The following is the Tinypng test data (using Apple mac m1):


      Before : 1918x1731px /4.2MB -> After : 1918x1731px / 1.4MB (-68%) Time : 1.85 s

  • Fixed Color png

    The number of colors of the custom PNG image ranges from 1 to 30000.


Choose the right png compression method


Usually, using Tinypng compression can achieve a relatively ideal compression effect. However, the following png compression test table shows that in some cases, such as illustrations with multiple gradient colors and png images with solid color blocks, Tinypng will have a more obvious grainy feeling. In this case, you can use 6000c to compress png to retain the smooth gradient effect.


In short, for common PNG material images, please use Tingpng, and for colorful illustration PNG, use 6000c or set the number of colors in the fixed color to achieve the best compression effect.
