PDF Textfix review
I’d reach for PDF Textfix if I spotted a misspelled heading in a handout I’d already exported. The Mac app edits existing PDF text and shows when a letter needs a substitute font. It requires an Apple silicon Mac with macOS 26 or later.
Change the letters on the page
Open a copy of your own PDF, then double-click the line with the typo. Change only the letters that need fixing. PDF Textfix starts with the font embedded in that line. If the font lacks a character, the app marks the substitute while you type. A scanned page has no editable text for this workflow.
Read the corrected line in the saved copy
I’d check where the next word starts. A longer correction can push later words along the line, and the editor flags that when it happens. Use “Save As” and open the saved PDF at the size people will read it. For comments that a collaborator should address in their original file, I’d use PDF Expert to mark the page and share the notes.
Anabel’s take
If I still have the layout file, I’d fix the typo there so the next export is right too. PDF Textfix is useful when the PDF is the only copy I have and the edit is small enough to check by eye.
