Why should I use this JPEG compressor?

If you work professionally with images and photos, they should be displayed with the best possible quality and be as small as possible.

However, all other compressors hide the numerous adjustment possibilities (or its developers do not know the possibilities of the JPEG algorithm) that are necessary to get the best out of the images. Either they just compress each image with the same settings or they state that they use clever algorithms to create the optimal image.

  • But what is the optimal image?
  • How would they know what your subjective quality requirements are for the image?
  • Do you want to compress a hero image or just any very low down on your website?
  • Are you running a first-world stock photo agency site where you want the images to be of excellent quality, or a third-world emergency site where mobile speed is of the essence?
  • Do you want to archive your images in high quality for later editing, or just send a meme/snapshot/screenshot via WhatsApp or email?

These are just a few examples of how many possible compression scenarios and use cases there are. Getting the most out of an image is therefore only possible with a preview of the result with maximum freedom in the settings.
