How to check fonts before sharing a presentation

You finish a presentation, send it to someone, and the slides look different on their computer. A missing font can be replaced automatically, changing line breaks, spacing, and even where text sits on a slide.

Check which fonts are installed on your computer, then compare them with the fonts used in the presentation. The Installed Fonts tool can show and preview fonts on a desktop computer, but it does not inspect a presentation file or tell you what fonts another person has.

Check the fonts before sharing

1. Open Installed Fonts in Chrome or Edge on a computer. Other browsers may show a reduced version or no font list. Use the preview to try a line of text that appears in your slides.
2. Open the presentation in the app you used to make it. Check the font names used in the theme, slide layouts, titles, body text, charts, and text boxes. Look at more than the first few slides, since a font can appear only in a caption or chart.
3. Compare each font name with the list in Installed Fonts. Check the family name, not just whether a sample looks similar. Two fonts can look alike but have different names and different letter widths.
4. Decide how the recipient will use the file. If they need to edit it, check whether the fonts can be embedded or installed on their computer. If they only need to view it, make a PDF copy and check that version too.

For a presentation with many slides, make a checklist of the font names as you find them. Include unusual weights such as Light, Semibold, or Condensed. Some apps treat a font family and its styles as separate choices, and a missing style can change the appearance even when the main family is present.

What the result means

The font appears in Installed Fonts

Your computer can access that font, so you can preview it while editing. This does not mean it is included in the presentation, or that it is installed on the recipient's computer. Their operating system, presentation app, and font license all affect what they will see.

The font does not appear in the list

Your computer may not have that font installed, or your browser may not be able to show the full list. If you are not using Chrome or Edge on a computer, try one of those browsers before deciding the font is missing. Also check the name in the presentation app: a theme may refer to a font that is not currently used in the visible text.

The font appears, but the slide still looks different

The recipient may have a different version of the font, a different font style, or an app that lays out text differently. A font substitution can change how many words fit on a line. That can push a paragraph into another text box or make a slide look crowded, even when the substitute seems visually close.

How to prevent font changes

1. Use a font available to everyone. If you know which computers or operating systems will open the file, choose a font installed on all of them. If you are unsure, ask the recipient to check before you finalize the layout. Recheck line breaks after changing fonts.
2. Embed fonts in the presentation. In PowerPoint on Windows 11, open File › Options › Save, find Preserve fidelity when sharing this presentation, and select Embed fonts in the file. On macOS, open PowerPoint › Preferences › Save and look for the font embedding option. Embedding can increase the file size, and some font licenses do not allow it. If recipients need to edit the slides, choose the option to embed all characters when it is available.
3. Replace fonts you cannot embed. In PowerPoint, use Home › Replace › Replace Fonts to substitute an unavailable font throughout the deck. Choose a replacement that has similar letter widths, then inspect every slide for changed wrapping, alignment, or overflow. If you use another presentation app, look for its font replacement command.
4. Install the font only when you have permission. If the recipient must edit the original deck, they may be able to install the same font from an authorized source. On Windows 11, use Settings › Personalization › Fonts to manage installed fonts. On a Mac, use the Font Book app. Do not send a font file unless its license permits sharing.
5. Export a PDF for viewing. A PDF usually keeps the slide layout more consistent, but it is not a substitute for an editable presentation and may not preserve animations or transitions. Open the exported PDF and check the slides before sending it.

Check the file on another computer

The most reliable check is to open a copy of the presentation on a computer that does not have your usual fonts, or ask the recipient to open it before the final handoff. Look for text that wraps differently, characters that change shape, or text that extends past a box. If the layout matters, check both the editable file and the PDF version you plan to share.

Installed Fonts previews fonts available to your computer. It cannot confirm that a presentation embeds them correctly or predict every change another app may make.
