What's New

Warning! May be buggy!

  • SVG optimizatinos via SVGO.
    • In this alpha build you must have Node.js 7 installed in /usr/local/bin/node and enable SVGO in ImageOptim's Preferences first.
    • SVGO may be lossy for some SVG files, especially scripted ones.

There are big under-the-hood changes in handling of file inputs and outputs. Affected areas:

  • Display of unoptimized and optimized file sizes (BTW, now % optimized is shown only when some optimizations were done)
  • Restarting optimizations again.
  • Reverting to original.
  • Cleanup of temp files.

If something is weird, please file bug on GitHub! (and include log from Console.app)
