FAQs

How do I mass delete all comments on a PDF?

While Smallpdf doesn’t currently offer a one-click “select all” option, you can remove multiple comments quickly by selecting them one by one and deleting them with the trash icon.

How do I stop comments from showing on a PDF?

If you simply want to hide comments without deleting them, open the file in a PDF viewer and disable the comments or annotations view. For a permanent solution, delete the comments using Smallpdf.

What is the best way to flatten a PDF?

After removing comments and highlights, use Smallpdf’s Flatten PDF to make the changes permanent. Flattening merges all visible elements into a single layer, ensuring your edits can’t be modified.
