FontFlex makes the internet more accessible, comfortable, and enjoyable for everyone – regardless of visual abilities or reading preferences. Whether you're reading articles, studying online, or browsing your favorite sites, FontFlex helps you read with clarity and confidence. READ EVERY WEBSITE YOUR WAY Make the font size bigger or smaller on any web page, and it stays that way the next time you visit. Switch to a clean sans serif typeface when a site's default is hard to follow, or choose a serif when you want a calmer, book-like page. Turn on dark mode colors for night reading, or a warm cream background to take the glare out of long articles. Everything happens inside Safari, because FontFlex is a Safari extension. There is no second browser to learn and nothing to copy or paste - open a page the way you normally would and your typeface, size and colors are already applied. BUILT FOR EVERY READER - Low vision and large print readers who need text bigger than a site allows - Students reading long articles and research pages in the browser - Older readers who would rather not zoom in on every single page - Night readers who want a darker page and softer contrast - Designers and developers checking how a page looks in another typeface ON ALL YOUR DEVICES FontFlex is one Safari extension for iPhone, iPad and Mac. Optional iCloud sync keeps your fonts, colors and profiles the same on all three, so a site you set up once reads the way you want everywhere.
