Turn any website into a brand kit
A free Chrome extension that extracts any website’s brand: download the logo, get the color palette with hex codes, identify the fonts, and export a style guide, brand book, or CSS. No account, no telemetry, nothing leaves your browser.
Version 4.0.0 · Chrome and Edge · free, with no paid tier.
Logos other tools miss
It reads the page the way a browser does: declared logos, tab icons, home-screen icons, embedded SVG — including sprite-based logos, where the drawing lives elsewhere on the page and simpler tools download an empty box. Partner grids, payment marks, and interface icons are filtered out, and every download keeps the original format, so a crisp vector logo stays a crisp vector logo.
Every color, named — and where it’s used
The color palette is weighted by the area each color actually paints, so the page’s real color leads. Every color gets a plain name like Terracotta, says where it works — header background, button fill — and whether dark or white text reads on it. The hex codes are one hover away, and the whole palette is said out loud in two written sentences: “leads with warm amber over cream”.
The fonts, identified
Headings, body, and buttons, each answered plainly — Georgia, 20px, regular — with who serves the font: Google Fonts, Adobe Fonts, or built into your computer. The full technical declaration is a click away for whoever is going to rebuild it.
A check-up in plain English
Does the page agree with itself? Text that is hard to read on its background, two colors so close nobody chose both on purpose, one heading wearing different fonts on different pages. Each finding is a sentence with the fix implied — and a colorblind check shows which colors stop being distinguishable for the roughly one man in twelve who cannot separate red from green.
It remembers the site, not just the page
As you browse more pages, each color says whether it is on every page or this page only — that is the difference between a brand color and one article’s illustration. Come back later and the panel says what changed: a new color, a shifted shade, a swapped font. And any two of your last twenty sites can stand side by side — palettes, fonts, page shapes — long after their tabs are closed.
Save: the whole kit, one click each
One tab holds every export. A brand book that opens anywhere, a logo pack with white and black versions, a shareable brand sheet, a style guide PDF, a ready-to-use stylesheet, a page blueprint, a starter page, and a ZIP of everything. Or press Copy for AI and paste the whole brand into ChatGPT, Claude, or v0 and ask it to build you something in this style.
What leaves your machine
Nothing, until you click a link.
- Collected: nothing. No account, no sign-in, no telemetry, no analytics, and no server of ours the extension ever talks to.
- Stored: locally, never sent. Your settings and, for the last 20 sites you inspected, the scan results themselves — the colors and fonts found — sit in the browser’s own extension storage. That is what lets the panel say a color is on every page of a site, and what changed since your last visit. Clearable from the panel in one click, removed when you uninstall, never synced to another device.
- Transmitted: nothing. A scan reads the page already open in front of you. Downloading an asset fetches it from the site serving it — the same request your browser already made to show you the page — and no third party is involved at any point. The only time anything leaves is when you click a link yourself.
Why a newsletter company built a brand tool
MailerDot writes daily newsletters for towns, and that work is one long parade of local businesses whose brand exists only on their website. We kept rebuilding the same kit by hand until the tool that does it was good enough to give away. So it is given away: free, no account, no upsell, and the only link back to us is the credit in its footer.
