How to Edit Footnotes in PowerPoint Slides
Learn how to edit footnotes in PowerPoint slides, which are usually plain text boxes at the bottom, and update them in the UniPPT slide editor.
Footnotes on a slide are easy to get wrong. A source citation has a typo, a statistic has been updated, or a note needs to move to a different number after you reorder slides. You search the menus for a footnote option and find nothing like the one in a word processor. This guide shows how to edit footnotes in PowerPoint slides, and how to make the change in UniPPT, the slide editor included in the OmniDoc desktop client.
The short version is that a slide footnote is usually a small text box placed near the bottom of the slide, with a matching number or symbol in the body text. PowerPoint does not create, number or link those notes for you the way Word does. That means you edit the note text directly and keep the markers correct yourself.
The steps below cover a typical .pptx deck. They also explain what to do if you only have a PDF of the slides, and how to check the result before you share the file.
How do you edit footnotes in PowerPoint slides? The short answer
Treat each footnote as an ordinary text box: find it on the slide, change the words, and make sure the marker in the body text still points to the right note.
| Your situation | What to do | Why |
|---|---|---|
| The note wording is wrong or outdated | Edit the words inside the footnote's text box | Slide footnotes are plain text, so the wording lives in that box |
| You added or removed a note, so the numbers no longer match | Update each superscript marker by hand | PowerPoint does not renumber markers automatically |
| You want to make the edit in UniPPT | Open the deck in UniPPT in the OmniDoc desktop client and edit there | UniPPT is the slide editor in that client |
| You only have a PDF of the slides | Use the PDF editor to edit the paragraph text, then check it | The PDF editor can edit paragraph text in place |
| The same note appears on several slides | Find and edit every copy, then check each slide | Repeated notes are usually separate text boxes, so one edit does not carry over |
Before you start
A few checks save time and prevent mistakes.
- Confirm you have the right file type. If the note sits in a Word document, you are editing real footnotes there. Slide notes are text boxes, so editing the wrong file wastes time.
- Keep a copy of the original deck. Changing text in a box can shift the layout, and you may need the original to compare or restore.
- Get the source wording and note order. Markers must match the sequence of notes, so check the source document before you renumber anything.
- Check whether you have a .pptx file or a PDF. The method differs. The steps below assume an editable .pptx file.
- Install the OmniDoc desktop client if you want UniPPT. You can download it from download.omnidoc.top. It runs on Windows, macOS and Linux.
Editing a footnote in UniPPT, step by step
The steps describe the general operation of editing a slide footnote. Follow the same order in any slide editor that lets you work with text boxes.
- Open the deck and go to the slide with the footnote. Scroll to the bottom edge of the slide, where footnotes usually sit in small type. If the note is not visible, check the body text for a marker, since the note may be placed differently on that slide.
- Find the marker in the body text. Look for a small raised number or symbol next to a word or figure. The marker tells you which note it refers to, so note its number before you change anything.
- Click into the footnote text box and select the words you want to change. Editing inside the existing box keeps the note in its position and preserves its formatting.
- Type the correction. Keep the font size, font and color the same as the other notes in the deck, so the correction does not stand out from the rest of the slide.
- Update the marker if the numbering changed. Select the number in the body text, apply superscript formatting, and type the new number. Do this for each affected marker, because PowerPoint will not do it for you.
- Repeat the edit on every slide where the note appears. Repeated notes are usually separate text boxes, so search through the deck and change each copy.
- Save the file under a new name. Keeping the edited deck separate from your original copy makes it easy to compare the two if a problem appears later.
If you only have a PDF of the slides, the PDF editor in the OmniDoc desktop client can edit paragraph text in place. It is a good choice for a quick correction to wording, but check the page carefully afterward, since small text near the bottom edge is easy to misalign.
Check the result
Once the edits are saved, review each affected slide before you share or present the deck. The table below covers the checks that catch a common problems.
| Check | How to see it | If it's wrong |
|---|---|---|
| Wording matches the source | Read the note aloud or compare it line by line with the source document | Retype the words and check again |
| Markers match the notes | Confirm each marker on the slide has one note with the same number | Renumber the marker, then check the next slide |
| Text stays inside the slide | Look for text that runs past the edge or overlaps the body | Shorten the wording or resize the box, then move it back into place |
| Font and color are consistent | Compare the edited note with the other notes in the deck | Reapply the font size, font and color from a neighboring note |
| The file opens cleanly | Reopen the saved file in UniPPT or PowerPoint | Restore the copy you kept before editing, then repeat the steps |
❓ FAQ
1. Can I edit a footnote in PowerPoint the same way as in Word?
No. Word has a footnote feature that numbers and places notes automatically. On a slide, a footnote is a text box you edit by hand, and its number is a marker you also change manually.
2. Why doesn't my footnote number update when I add a new note?
PowerPoint does not renumber footnote markers. After you add or remove a note, go through the slides and change each superscript number so it matches the order of the notes.
3. Can I edit footnotes in a PDF of my slides?
Yes, with the PDF editor in the OmniDoc desktop client, you can edit paragraph text in place. Check the page afterward, because changes to small text at the bottom of a slide can shift its alignment.
4. What should I do if the corrected footnote is too long for the slide?
Shorten the wording, or resize the text box so it fits above the bottom edge without overlapping the body text. Keep the font consistent with the other notes so the slide still looks uniform.
📝 Summary
Editing a footnote on a PowerPoint slide means changing the text box at the bottom of the slide and keeping its marker in the body text accurate. Because PowerPoint does not number or link these notes for you, check every affected slide after you edit. Keep a copy of the original deck so you can compare the two versions if something looks wrong.
