  • In-place compare function (alternativelly display the original image over the optimized image to notice small pixel changes).
  • Compress files to desired filesize threshold.
  • Fast processing (all is done in memory); See instant results including resulting filesize
  • Batch support (process multiple files at once).
  • Transparency handling options.
  • Decide if you want to keep metadata (comments, IPTC, Adobe XMP, EXIF profiles, ICC profiles). Unsupported metadata is removed
  • Transfer metadata between image formats (destination format must support them)
  • Common tools: pan and zoom, rotate, flip
  • Basic image adjustments: brightness, contrast, gamma, invert
  • Visually reduce number of unique colors for PNG and GIF images in order to reduce filesize
    (two quantization methods are available: Xiaolin Wu and NeuQuant neural net)
  • Resize image by using well known resample filters (ex: Lanczos3, Catmull Rom, Bicubic, and others)
  • Out-of-the-box support for external PNG optimizers (optipng, pngout, etc)
  • The compression and the results are comparable to those of commercial products, even higher.
  • Adaptive logarithmic tone mapping algorithm (Drago) used for HDR images.
  • Runs on all versions of Windows.
