Change Fonts and Text Size on Any Webpage
WebTypographer is a free Chrome extension that lets you customise the typography of any website in real time — font family, size, weight, colour, line height and spacing — without reloading the page. Whether you have low vision, dyslexia, or simply prefer reading in a different typeface, this extension puts you in control.
Add to Chrome — It's FreeWhat You Can Do
Font Family
Choose from 30+ fonts including all major Google Fonts (Roboto, Inter, Merriweather, Fira Code…) or load any custom font via URL.
Proportional Text Scaling
Scale all text up or down by percentage (−50% to +100%). Headings and body text resize together, keeping their proportions.
Weight & Style
Switch between Light, Regular, Medium, Bold and Black. Toggle italic on any website with one click.
Line Height & Spacing
Adjust line height, letter spacing and word spacing independently for maximum comfort.
Text & Background Colour
Override text and background colours. Six ready-made palettes: Paper, Dark, Sepia, Blue, Warm, B&W.
Per-site & Global Settings
Settings saved per website or applied globally. Switch between modes in one tap.

Frequently Asked Questions
Is WebTypographer free?
Yes, completely free. No subscription, no account, no in-app purchases.
Does it work on all websites?
It works on virtually any website. A small number of sites with very strict Content Security Policies may limit some features.
Will it slow down my browser?
No. The extension injects a small CSS rule — there is no JavaScript running continuously on the page.
Does it collect any data?
No. All settings are stored locally on your device using Chrome's standard storage API. Nothing is ever sent to any server.
Can I use a font that isn't in the list?
Yes. Select 'Custom font URL' at the bottom of the font list and paste any Google Fonts or CSS URL.
What is the difference between 'This site' and 'All sites'?
'This site' saves settings only for the current domain. 'All sites' applies your preferences everywhere as a global default.
Privacy
WebTypographer does not collect, store, or transmit any personal data. All your preferences are saved exclusively on your own device. When you select a Google Font, your browser contacts fonts.googleapis.com to download it — this is the only external connection and is initiated entirely by your choice.
