I mostly stroll through Wikimedia Commons looking for PNG images that need improvement. Changes I have made include:

  • Optimizing poorly-encoded PNG images to losslessly reduce file size
  • Re-cropping badly-cropped images
  • Replacing low-resolution images with new ones from better sources
  • Properly extracting images from PDFs or webpages to replace screenshotted images
