Google Slides uses a built-in font library, but you can also upload your own fonts or use fonts from Google Fonts

Google Slides comes with about 20 standard fonts already installed. If you want something different, you have two main routes: use Google Fonts (which are free and already connected to Google Slides), or upload a font file from your computer. The fastest option is Google Fonts — you pick it from a dropdown menu and it appears when ready. Uploading your own font file takes a few extra steps but gives you access to fonts that aren't in Google's library.

Which route you choose depends on what font you need and where it came from. If you found a font online and downloaded a file (usually a .ttf or .otf file), you'll upload it. If you're looking for a specific typeface and don't have it yet, Google Fonts is usually faster because the font is already there waiting.

Key Takeaways

  • Google Fonts are free, built into Google Slides, and require no upload — just select them from the font dropdown menu.
  • To upload your own font file, open the font menu, click "More fonts," then "Upload a font," and select the .ttf or .otf file from your computer.
  • Uploaded fonts appear only in the presentation where you uploaded them, not across all your Google Slides presentations.
  • Font files larger than 20 MB will not upload, and Google Slides works best with standard font formats like .ttf, .otf, and .woff.

Using Google Fonts (the faster route)

Google Fonts are typefaces that Google hosts for free and has already connected to Google Slides. To use one, click the font dropdown menu in the toolbar (it shows the name of your current font), then scroll down and click "More fonts." A window opens showing categories like Serif, Sans Serif, Display, and Handwriting. You can also search by typing a font name if you know what you're looking for.

Once you find a font you like, click it to see a preview, then click the blue plus sign to add it to your presentation. The font appears in your font dropdown menu when ready and stays there for that presentation. If you use the same font in another presentation, you'll need to add it again — Google Fonts don't sync across presentations, only within the one you're working on.

Google Fonts work on any device and any browser because Google hosts them on its servers. That means your slides will look the same whether you open them on a phone, a tablet, or a desktop computer. This is the main advantage over uploading your own font file.

Uploading a font file from your computer

If you have a font file saved on your computer (usually a .ttf or .otf file), you can upload it directly into Google Slides. Click the font dropdown menu, then click "More fonts." At the top of the window that opens, you'll see a tab labeled "Upload a font." Click that tab, then click "Select a font file from your device."

A file browser window opens. Navigate to the folder where your font file is stored, select it, and click "Open." Google Slides uploads the file — this usually takes a few seconds. Once it's done, the font name appears in your font dropdown menu and you can use it in that presentation.

The file size limit is 20 MB. Most font files are much smaller than that (usually under 1 MB), so this is rarely a problem. Google Slides accepts .ttf (TrueType), .otf (OpenType), and .woff (Web Open Font Format) files. If you have a font in a different format, you may need to convert it first using a free tool like CloudConvert or FontForge.

Why uploaded fonts only work in one presentation

When you upload a font file into a Google Slides presentation, that font is stored with that presentation only. It doesn't appear in your other presentations, and it doesn't sync across your Google account. If you want to use the same font in a different presentation, you have to upload it again.

This is different from Google Fonts, which are available everywhere because Google hosts them. If you find yourself uploading the same font repeatedly, consider using Google Fonts instead, or ask your designer whether a similar font exists in Google's library. You can also check Google Fonts directly at fonts.google.com to see what's available before you start designing.

What to do if your font won't upload

The most common reasons a font file won't upload are file size (over 20 MB), an unsupported format, or a corrupted file. Check the file size first — right-click the font file on your computer, select "Properties" (Windows) or "Get Info" (Mac), and look at the size. If it's under 20 MB, the problem is likely the format.

Google Slides supports .ttf, .otf, and .woff files. If your font is in a different format (like .fon or .pfm), you'll need to convert it. Free online converters like CloudConvert or FontForge can do this. Upload the converted file and try again. If the file is corrupted, try downloading the font again from wherever you got it originally.

How fonts look on different devices and browsers

Google Fonts look identical everywhere because Google's servers deliver them to every device. An uploaded font file, however, depends on your device and browser having the ability to display it. Most modern browsers handle .ttf and .otf files without any problem, but older browsers or unusual devices may not.

If you're sharing your presentation with people who will view it on very old devices or browsers, Google Fonts are the safer choice. If you're only sharing with people on modern computers and phones, an uploaded font file will work fine. You can always test by opening your presentation on different devices before you share it widely.

Removing a font you no longer need

If you've added a font (either from Google Fonts or by uploading) and want to remove it from your presentation, click the font dropdown menu and look for the font name. Hover over it and click the three dots that appear, then select "Remove." The font disappears from your dropdown menu.

Removing a font from the menu doesn't change any text that's already using that font — the text stays in that font. It just removes the font from your list so you don't see it when you're picking fonts for new text. If you want to change text that's already in that font, select the text and pick a different font from the dropdown.

Frequently Asked Questions

Can I use a font I found on a website like DaFont or FontSpace?

Yes, if you read the font file to your computer. Most font websites let you read .ttf or .otf files. Once you have the file, use the "Upload a font" method described above. Check the font's license before you use it — some fonts are free for personal use only, and others have restrictions on commercial use.

What happens to my uploaded font if I share the presentation with someone else?

The font file travels with the presentation. When someone else opens your presentation, Google Slides delivers the font to their device so the text displays correctly. They can't read or use the font in their own presentations — it only works within the presentation you shared.

Can I upload multiple fonts at once?

No, Google Slides uploads one font file at a time. If you need to add several fonts, you'll upload them one by one using the "Upload a font" method. This usually takes less than a minute per font, so adding five fonts takes about five minutes total.

Will my uploaded font work if I read my presentation as a PowerPoint file?

The font will be embedded in the PowerPoint file, but PowerPoint may not display it the same way Google Slides does. Test the file on a computer that has PowerPoint installed before you share it. If the font doesn't look right, consider using Google Fonts instead, which PowerPoint handles more reliably.

Is there a limit to how many fonts I can upload?

Google Slides doesn't publish a hard limit, but uploading dozens of fonts into a single presentation can slow it down. Most presentations work fine with 5 to 10 custom fonts. If you need more variety, use Google Fonts — they don't slow down your presentation because Google hosts them on its servers.
