design tool
Find the fonts used in a PowerPoint
Choose a .pptx to see every font it names: the theme's heading and body fonts, fonts set directly on slides with the slide numbers, fonts used in masters and layouts, and which are embedded in the file. It answers the question before you send the deck: will it look the same on someone else's computer?

How it works
- 1
Choose the .pptx
Use the version you are about to send, since fonts change as people edit.
- 2
Read the table
Each row is one font, with where it is used: the theme, particular slides, or masters and layouts.
- 3
Look at the embedded column
A No means the font travels by name only, and the other computer must have it installed.
- 4
Fix before you send
Install, embed or replace any font the recipient may not have, then check again.
Theme fonts and direct fonts
PowerPoint has two ways to set a font. The theme names a heading font and a body font, and text that uses the defaults follows them, which is why changing the theme fonts restyles a whole deck at once. Text can also have a font set directly, overriding the theme on that run of words. Slides that were pasted in from other decks often bring direct fonts with them, so a deck that should use two fonts quietly uses six. This tool lists both kinds, and it resolves the theme placeholders PowerPoint writes in the file, such as +mn-lt for the body font, into the real font names.
What happens when a font is missing
If the computer opening the deck does not have a font, PowerPoint substitutes another one. The replacement has different letter widths, so lines break in new places, text overflows its box, and carefully aligned layouts slip. On a Mac, Windows fonts such as Segoe UI are often absent, and on Windows many design fonts are absent. The safest decks use fonts both systems share, fonts the recipient is known to have, or embedded fonts. The notice under the table appears whenever any listed font is not embedded.
Embedding fonts in a PowerPoint file
PowerPoint for Windows and Mac can embed the fonts a deck uses, from the save options, so the file carries them. Embedding only works for fonts whose licence allows it, and the file gets bigger. You can embed just the characters used, which keeps the file smaller but stops others editing the text properly. After embedding, run this tool again: fonts that made it into the file show Yes in the embedded column. Fonts that refused to embed because of their licence still show No.
Fonts and exported PDFs
Exporting the deck as a PDF embeds the fonts needed to display it, so a PDF looks the same everywhere even when the .pptx would not. If the recipient only needs to view the deck, sending a PDF avoids the missing font problem entirely. When they need to edit it, the .pptx and its fonts have to travel together, and this list is the checklist of what they need installed.
Choosing fonts for a deck that travels
If a deck goes to many people, pick fonts that are widely available or free to install, use one family for headings and one for body text, and avoid setting fonts directly on individual text boxes. The presentation builder offers 42 fonts and applies them through the theme, so the whole deck changes together. When a finished deck is exported as an editable PPTX, the fonts named in it are the ones the recipient needs, and this tool is a quick check of exactly which ones those are.
Reading the slide ranges
The where column lists slides as ranges, such as 3 to 7, 12, so a font used on one stray slide stands out. That single slide is usually the one pasted from an old deck. Changing its text back to the theme font, by selecting it and choosing the theme heading or body entry at the top of PowerPoint's font list, brings it into line. Masters and layouts are listed separately because their fonts affect every slide built on them.
Limits
- It lists font names the file asks for. It cannot tell whether a font is installed on your computer or a client's.
- Embedded fonts are listed but not extracted; their licence usually forbids that anyway.
- Fonts used only inside charts or SmartArt live in other parts of the file and may not appear.
- The .ppt binary format is not supported; save as .pptx first.
What it does not do
- It does not replace fonts in the deck.
- It does not check font licences.
- It does not upload the presentation.
Questions people ask
How do I see which fonts are used in PowerPoint itself?
In PowerPoint for Windows, the Replace Fonts option on the Home tab lists the fonts in use. Save options also show embedding choices. This tool adds the slide numbers for each font and works without PowerPoint, which helps when you have only the file, on a computer without Office.
Why does my deck list a font I never chose?
Pasted slides, copied text boxes and templates bring their own fonts. A single slide pasted from an old deck can introduce a font that appears nowhere else. The slide numbers in the table show exactly where it lives, so you can change it back to a theme font there.
Can I extract an embedded font from a PPTX?
The embedded font data is inside the file, but it is stored in a protected form and font licences almost always forbid extracting it for other use. This tool only reports that a font is embedded. To use the font elsewhere, get it from its designer or distributor under a licence that allows it.
Will Google Slides keep my PowerPoint fonts?
Google Slides uses its own font library. When you open a .pptx there, fonts it does not have are replaced, usually with a similar Google font. Check the list here against the fonts available in Google Slides, and swap any missing ones before converting, so the replacement is your choice rather than an automatic one.
What do the names +mj-lt and +mn-lt mean?
They are theme placeholders in the file: major Latin, meaning the heading font, and minor Latin, the body font. Text marked with them follows the theme, so changing the theme fonts changes it too. The tool replaces them with the real font names from the theme so the list makes sense.
