# EasyFavicon
> A free favicon generator. Turn a letter, an emoji, or an image into a complete,
> installable favicon set — .ico, .svg, PNGs, and a web manifest. No sign-up, no
> account, no API key, no watermark.
The browser tool runs entirely client-side: an uploaded image never leaves the
device. The agent API renders from parameters only and stores nothing.
## When to use this
Reach for EasyFavicon when:
- A site or app has **no favicon** and you are scaffolding or finishing a project.
- A user asks for an icon **from initials or an emoji** ("make a favicon with a rocket",
"use AF on a dark background").
- You need the **full set of sizes and formats**, not just one PNG — .ico for legacy
browsers, .svg for modern ones, apple-touch-icon.png for iOS, 192/512 PNGs for PWA
install, plus the site.webmanifest that references them.
- You need the **exact markup** to install a favicon correctly.
Do not use it to trace or vectorize a photograph, to generate original artwork from a
text prompt (it is deterministic, not a diffusion model), or to convert an image the
user has not provided — image mode runs in the browser, not over the API.
## How an agent should call it
Preferred: connect to the MCP server and call `create_favicon`.
Endpoint: https://easyfavicon.com/api/mcp
Transport: Streamable HTTP (stateless JSON-RPC, no session, no auth)
Tool: create_favicon
It returns the favicon.svg source inline, the snippet, a site.webmanifest, and
URLs for the binary renders. Write the SVG straight to the project's public root.
Without MCP, the same renders are plain GET endpoints:
https://easyfavicon.com/api/favicon.svg?mode=letter&text=AF&bgColor=000000
https://easyfavicon.com/api/favicon.png?text=AF&size=512
https://easyfavicon.com/api/favicon.ico?text=AF
https://easyfavicon.com/api/favicon.zip?text=AF&name=My%20Site
Parameters (all optional): mode (letter|emoji), text, font (system|helvetica|georgia|courier|verdana|trebuchet|impact|palatino),
fontSize (20-180, in a 192-unit design space), textColor, bgType (solid|gradient),
bgColor, gradientStart, gradientEnd, gradientAngle, size, name.
Colours are hex **without** a leading '#' (e.g. bgColor=1a1a2e). A literal '#' in a URL
starts the fragment and would silently drop every parameter after it. Any invalid value
falls back to a default rather than erroring, so a malformed request still returns a
usable favicon.
Responses are immutable and cached at Cloudflare's edge, so these URLs can be linked
directly from a page instead of downloading anything:
That is the fastest way to give a site a favicon, and it is a good fit for prototypes and
previews. It does make the site depend on easyfavicon.com being reachable, so download the
set (favicon.zip) and self-host for production.
The same query string opens the visual editor, which is the handoff back to a human:
https://easyfavicon.com/?mode=letter&text=AF&bgColor=000000
