User:PNG crusade bot


 * 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.


 * Please leave comments on the feedback page.


 * 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.
