About

Font Size Increaser gives you complete control over how any website looks and reads. Instantly scale text, zoom in on any part of a page with a circular magnifier, and apply eye-friendly reading filters — no site settings needed.

FONT SIZE CONTROL — 50% TO 300%
Scale all text on any page from 50% up to 300% using a simple slider. Changes apply instantly to headings, paragraphs, links, buttons, tables, code blocks, and more. Dynamically loaded content (infinite scroll, AJAX) is handled automatically. Settings sync across all your devices via Chrome Sync.

SCREEN MAGNIFIER
Activate a circular zoom lens that follows your cursor — magnify any area from 1× to 5×. Toggle it instantly with the Alt+M keyboard shortcut or from the popup. Works on text, images, and all page content.

READING MODES
Choose from four visual filters to reduce eye strain:

Off — normal view
Sepia — warm amber tone for long reading sessions
Night — dark inversion mode for low-light browsing (images stay natural)
Focus — muted saturation to reduce visual distractions
