Font Changer for WhatsApp Web

Change the font, size, and weight of WhatsApp Web text. Your choice is remembered across sessions.

Change the font on WhatsApp Web to anything you like. Font Changer for WhatsApp Web lets you set the font, size, and weight of the text on web.whatsapp.com — chosen from the fonts already installed on your computer. Pick a font once and it's remembered and re-applied automatically every time you open WhatsApp Web. WHAT YOU CAN DO • Choose any installed font from a searchable dropdown — each name previewed in its own typeface • Set the text size (8–24px) • Adjust the font weight, or leave it untouched • Apply your font to just the messages, or the entire interface • Toggle it on/off instantly without losing your settings • See changes live — no page reload needed HOW IT WORKS The extension reads the list of fonts installed on your device and applies your choice directly on WhatsApp Web. Nothing is downloaded — it only uses fonts you already have. PRIVACY FIRST This extension collects nothing and sends nothing. No analytics, no tracking, no accounts, no external servers. Your settings are stored locally in your browser (and sync across your own devices only if your browser's sync is turned on). It never reads or transmits your messages, contacts, or any page content.
