StylePatch is a website theme changer and appearance customiser for Chrome and Edge. It restyles the page in front of you in seconds: background, text and link colours, font size, font family, eye-care filters and seven ready-made themes. Every change previews live, without a reload, and can be saved for that site so it returns the next time you visit. No account, no advertising and no analytics. Five sites can be saved for free; a licence removes that limit and adds sync and a default theme.

Everything it does
The core features at a glance.
Link colour adjusts itself for readability against your chosen background.
A contrast hint warns you when text or link colour falls below comfortable reading levels.
Scale text from 80% to 150%, so small print becomes readable without changing the site's layout.
Swap the page font for a system font, or load one of six web fonts: Roboto, Open Sans, Lora, Merriweather, Noto Sans SC and Noto Serif SC.
Apply a grayscale filter or a warm sepia eye-care tint when a page is too bright or too cold.
Also included
- Seven one-click themes: Light, Warm Tone, Green, Dark, Sepia, Night Blue and High Contrast.
- Settings are stored per site and restored automatically on your next visit; www and non-www addresses share the same settings.
- Turn the whole extension on or off with one switch, without losing a single saved style.
- Add any site to an exclusion list so banking, design tools and other sensitive pages stay untouched.
- A config manager lists every styled site with search and delete, and exports or imports JSON backups.
- Six interface languages: English, Simplified Chinese, Japanese, German, Spanish and French.

Free vs Premium
The free tier is a complete tool, not a trial. Premium is optional.
Free
background, text and link colours, contrast hint, 80–150% text size, system and six web fonts, grayscale and eye-care filters, all seven themes, live preview, five saved sites, the global switch, the site blacklist, Config Manager, JSON export and import (up to five sites), and six languages.
Premium
unlimited saved sites, full backup restore including the default theme, one default theme for sites without their own settings, and cloud sync through your browser account. One licence key activates on two browsers, and removing the licence from one browser frees that slot again.
The licence is optional; the free tier is a complete reading tool, not a trial. Premium keeps working offline and asks the licence server for a check about every two hours. An unreachable server never locks you out.

💌 A Note to You
Thank you for using StylePatch. This little tool was born because I wanted my eyes to feel more comfortable browsing the web late at night.
If it helps you too, that's already the best reward I could ask for.
Of course, if you'd like to ☕ buy me a coffee, it would truly make my day — and keep me motivated to make StylePatch even better.
