Compression Settings

The Compression section allows you to configure compression options. Note that these options have no effect on SVG format exports:

• Enabled: Toggle compression on or off. By default, compression is disabled.

• Quality

  • 0 - smallest/worst
  • 100 - biggest/best
  • Only works for JPG, WebP

• Progressive JPG: Toggle whether to export Progressive JPG for JPG files. By default is on.

  What is Progressive JPG?\ Baseline JPG and progressive JPG differs in the way it compresses and displays images — especially if you have a slow internet connection.\ The standard JPG format loads images one line at a time, from top to bottom, and each line is already pixel perfect. Hence, it can take a while for the picture to load fully.\ As for progressive JPG, the image appears all at once as a whole, but it’ll be blurry and pixelated a first. Gradually, you will see a clear and fully loaded image.

• Quality: Adjust the image quality during compression. The default quality value is 0.9. Quality refers to the level of detail and sharpness in the image. Lower values reduce quality, while higher values maintain quality. The best practice for changing this value depends on the specific requirements of your project.

• PNG Level

  • The optimisation level between 1 to 6. The higher the level, the higher the compression. Any level above 4 is not recommended.
  • Only works for PNG

• WebP Method

  • Specify the compression method to use. This parameter controls the trade off between encoding speed and the compressed file size and quality. Possible values range from 0 to 6. Default value is 4.When higher values are used, the encoder will spend more time inspecting additional encoding possibilities and decide on the quality gain. Lower value can result is faster processing time at the expense of larger file size and lower compression quality
  • Only works for WebP

• AVIF Quality

  • 0 - lossless
  • 63 - worst
  • Only works for AVIF
