Image optimizer to reduce the size of images Source


Optimize your images with OptiImage, a useful image compressor that supports PNG, JPEG, WebP and SVG file types.

It supports both lossless and lossy compression modes with an option whether to keep or not metadata of images. It additionally has a safe mode, where a new image is created instead of overwriting the old one.

It uses the following tools:

  • oxipng for PNG images
  • jpegoptim for JPEG images
  • scour for SVG images
  • cwebp for WebP images
