User:PNG crusade bot

From Wikipedia, the free encyclopedia

  • This bot automatically converts images on the English Wikipedia to the more efficient PNG format. Only images that would see a decrease in file size are automatically converted.
  • This bot is NOT so that you can be lazy and upload images in the wrong format for them to be converted later! Images uploaded by this bot will have its name as the uploader instead of yours, so you may not be notified if there is a problem with the image, such as being nominated for deletion.
  • If you want this bot to automatically convert an image, please understand that by doing so, this bot will be listed as the uploader instead of you. Thus, you may not be notified if your image is nominated for deletion. If you still want this bot to convert the image, tag the image with {{ShouldBePNG}}. Even though this bot can process images from other categories, I plan to primarily run it only on images tagged with {{ShouldBePNG}}.
  • Due to the trivial nature of image description pages, it is probably not necessary to preserve their revision history. But just to be sure, this bot preserves it anyway.

[edit] News

  • The source code has again been updated. Since the code is no longer contained in a single file, the code is available as a Base64-encoded ZIP file. —Remember the dot (talk) 01:27, 18 October 2007 (UTC)
  • The source code is now up-to-date. Many improvements have been made. For example, this bot now uses PNGOUT, which tends to produce smaller file sizes than the optiping+advpng combination. —Remember the dot (talk) 04:54, 21 March 2007 (UTC)
