↓ 02 – ImageOptim | macOS


ImageOptim makes images load faster. It removes bloated metadata. Saves disk space & bandwidth by compressing images without losing quality. ImageOptim is excellent for publishing images on the web (easily shrinks images “Saved for Web” in Photoshop). It’s useful for making Mac and iPhone/iPad applications smaller (if you configure Xcode to allow better optimization). ImageOptim removes EXIF meta­data, such as GPS position and camera’s serial number, so that you can publish images without exposing private information (but there’s an option to keep the meta­data if you need it).

  • Removes invisible junk – private EXIF meta­data from digital cameras, embedded thumbnails, comments, and unnecessary color profiles.
  • Reduces image file sizes — so they take up less disk space and down­load faster — by applying advanced compression that preserves quality.

PngOptimizer compresses graphics files and removes extra, unnecessary data without affecting quality.

  • Cleans your PNG files of useless or wrong information.
  • Reduces your PNG files weight.
  • Converts into PNG other lossless image formats (BMP, GIF, TGA).
  • Supports animated PNG (APNG).
