Sharp text in screenshots

PNG is lossless, which is why screenshots of text look sharp. The image is embedded losslessly, so small text in a screenshot stays readable. Transparent areas show as white on the page.

PNG files of photos can be large; if the result is too big for a portal, compress it, which converts photo-like images to JPEG.

Steps

  1. Add PNG files.
  2. Reorder them.
  3. Choose the page size.
  4. Save and download.
