How to Strikethrough Text in a PDF

Does strikethrough delete or erase the text underneath?

No. A strikethrough draws an annotation line across the selected text while keeping the underlying text intact. If you need to permanently redact or hide sensitive information, use our Whiteout or Redact tool instead.

Can I customize the color and thickness of the strikethrough line?

Yes. You can select any color from the palette (red, black, blue, gray, etc.) and adjust the stroke width to match your document typography.

How do I remove or undo a strikethrough line?

Click the Undo button in the top toolbar, or switch to the Select tool, click on the strikethrough line annotation, and press Delete or Backspace.

Will my strikethrough annotations show up in Adobe Acrobat and Preview?

Yes. The annotations are saved standard PDF vector graphics that display accurately in Adobe Acrobat, Apple Preview, Google Chrome, and all PDF viewers.

Is my PDF uploaded to any third-party server?

No. KissThePDF processes your PDF entirely within your browser memory. Your sensitive documents never leave your computer.
