FAQ

What should I do if the Smart Optimize button is grayed out?

  1. Make sure at least one image is selected on the current PDF page.
  2. Check whether you are in the relevant image editing context.
  3. Confirm that your account has membership permission for PDF editing.
  4. Select the image again and click Smart Optimize once more.

Can I undo the optimization result?

  1. If you just completed the optimization, first try Ctrl+Z.
  2. After undoing, check whether the image returns to its previous state.
  3. If needed, select the image again and run Smart Optimize again.

Does Smart Optimize change the image size?

  1. Smart Optimize mainly adjusts image sharpness, contrast, and color automatically.
  2. Its main purpose is to improve display quality rather than change image dimensions by itself.
  3. If you need to change image size, use other image editing actions together with this feature.

Why do some images show little or no visible change during batch optimization?

  1. First confirm that those images were successfully selected before you ran the command.
  2. Check whether the original images were already visually stable, because automatic optimization may produce only minor changes in that case.
  3. Select the target images again, run the feature again, and review the results one by one.
