JPG - 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.


  • Custom

    The image quality of jpg can be adjusted. The higher the value, the higher the quality. The default value is 100.

    After wasm is turned on, the mozjpeg algorithm is used to compress jpg images, which provides a stronger compression effect, but the conversion speed will be slower. For example, the following image CentralPark.jpg Quality 100 The conversion time is 0.07 s (1.1MB) when wasm is turned off, and 0.82 s (862.7KB) when wasm is turned on.


    Test image information: CentralPark.jpg 2048x490px / 823.9KB

  • Optimal

    Automatically set wasm to start, and set the quality parameter to 90 to convert jpg, so that the output jpg image quality and image file size achieve the best balance.


  • Lossless

    Automatically set the quality parameter to 100 to convert jpg so that the output jpg image does not lose any image details.


    Theoretically, each time you save a JPG, the image quality will be partially lost. However, in actual conversion tests, it was found that after 10 conversions with a quality of 100, there was no obvious loss in the image quality of the JPG image. For ease of understanding, I named it 'lossless'.
