PNGGauntlet is a .NET program that uses Ken Silverman's PNGOUT command line utility to optimize PNG files. Many PNG files output by popular graphics software packages like Photoshop or Fireworks are not as small as they could be - PNGGauntlet squeezes the last bit of size out of them. Furthermore, no information is lost during this process - the only thing that changes is the file size. Just select the files you want to optimize (or drag them onto the window), select where you want them to go, and click the button. PNGauntlet can also be used to convert JPG, GIF, TGA, PCX, and BMP files to PNG.
PNGGauntlet 2.1.2 & 2.1.3 (May 27, 2010)
* [Fix] Remove a debug output that shouldn't have shipped.
PNGGauntlet 2.1 (April 4, 2010)
Changelog
* [Feature] In Windows 7, the PNGGauntlet taskbar icon shows the progress of compressing files.
* [Feature] Each column can now be sorted, with a visual indication of the sort order like you'd expect.
* [Feature] Option for preserving file times when optimizing.
* [Feature] PNGGauntlet is now listed in the "Open With..." right-click menu for PNG, JPEG, GIF, BMP, PCX and Targa image files, allowing you to quickly start it with that file pre-loaded.
* [Feature] If filenames are provided as arguments to pnggauntlet.exe, they are automatically included in the list of files to compress. You can use this to make a right-click "Compress with PNGGauntlet" command.
* [Feature] Due to some confusion over this feature, when files get larger after being compressed PNGGauntlet now explains that it copied the originals to the output, not the larger files.
* [Feature] When no images are queued for compressing, text appears instructing you to drag and drop files onto PNGGauntlet.
* [Feature] The installer now prompts to launch PNGGauntlet immediately.
* [Feature] Overall progress bar resets when files are added or removed.
* [Feature] Start the output directory dialog on the currently-selected directory if there is one, or My Pictures if there isn't.
* [Feature] Doesn't let you choose an empty or nonexistant output directory. If the directory doesn't exist, it prompts to create it.
* [Feature] The list of files can be scrolled with the mouse wheel.
* [Feature] Prettier list view drawing.
* [Fix] Don't do anything if no files are selected to compress.
* [Fix] Arrows on the Advanced Options button match the current state even if you close the options dialog with the close box.
* [Fix] Fixed URL in the About dialog
* [Internal] PNGGauntlet now requires .NET Client Framework 3.5.
* [Internal] Lots of cleanup around how the GlacialList control draws, with fewer P/Invoke calls.
