ImageOptim can also be launched from <a href=/command-line.html>command line</a> or <a href=/sketch>Sketch</a>. </p> <section id=lossy> <h3>A special option for even smaller files</h3> <p>If you enable <samp>Lossy minification</samp> you'll get smallest file sizes possible.</p> <p>By default ImageOptim is very cautious and exactly preserves image quality, but if you allow it to change the quality — even only a little — it will be free to use much more aggressive optimizations that give the biggest results.

ImageOptim can apply lossy compression not only to <abbr>JPEG</abbr>, but <abbr>SVG</abbr>, <a href=https://kornel.ski/lossygif>anim <abbr>GIF</abbr></a> and <a href=https://pngmini.com/lossypng.html><abbr>PNG</abbr> as well</a>!</p> </section> </section> <section id=opensource> <h2>Open Source</h2><p>ImageOptim is free, open-source software under terms of the <a href=https://www.gnu.org/licenses/gpl-2.0.txt class=reference>GPL v2 or later</a>.
