# Custom font not loading

> Why your uploaded font might not show, and how to fix it.

If your uploaded custom font isn't applying on the public page, walk through this checklist.

## 1. Format

Supported: **WOFF2**, **OTF**, **TTF**.

WOFF2 is **strongly preferred** — smallest file size and best browser support. If you only have a TTF, [convert to WOFF2 online](https://www.fontsquirrel.com/tools/webfont-generator).

## 2. Size

Max **2 MB** per font file. Big fonts (multiple weights bundled into one TTF) often blow this limit. Use a single-weight WOFF2 instead.

## 3. License

This is on you — make sure you have rights to the font. Premium fonts from Google Fonts can be downloaded and uploaded; commercial fonts (Helvetica, Adobe foundry stuff) usually require a webfont license.

## 4. Browser cache

After re-upload, hard-refresh the public page (Ctrl+Shift+R / Cmd+Shift+R). Browsers cache fonts aggressively; the old one may stick around for a while.

## 5. Per-widget vs profile-wide

The infobox widget has its **own** font upload — it overrides only that widget. The profile-wide [Fonts panel](/appearance/fonts) sets the heading and body fonts. Make sure you're editing the right one.

## 6. Font-display behavior

We load custom fonts with `font-display: swap` — visitors briefly see a fallback font, then your custom font replaces it once loaded. If your font is a slow-loading TTF on a slow connection, this swap is noticeable.

## Still not working?

Open a thread in [Discord](https://biolovers.site/discord) with the font file attached and your username. We'll check the upload logs.
