关于 cataito
一个完全免费、纯前端、隐私优先的在线工具集合。
我们做什么
cataito 是一组面向开发者、设计师与普通用户的免费在线工具。我们把日常高频、却又不必依赖笨重软件的轻量需求——图标生成、图片压缩、配色提取——做成打开即用的网页工具。你不需要注册账号，不需要安装任何东西，打开浏览器就能用。
我们最坚持的一点是隐私优先：所有图片与文件都在你的浏览器本地处理，绝不会上传到我们的服务器。你的素材只属于你自己。
我们的工具
图标工坊 IconForge：上传一张图，生成多尺寸 .ico / .png 应用图标与 favicon，支持亮色与暗色双变体。
Favicon 生成器：一键生成多尺寸 favicon 图标包，覆盖桌面与移动端常用档位。
图片压缩：在肉眼几乎无感的前提下压缩 PNG / JPEG / WebP，减小体积、加快网页加载。
配色工具：从图片或关键词提取配色方案，快速得到可用的调色板。
我们的原则
纯本地处理。工具的计算全部发生在你的设备浏览器里，文件不上传、不存储。
无追踪、无账号。我们不投放第三方追踪 cookie，也不要求登录。你用完即走。
开源透明。整个站点公开托管在 GitHub，任何人都可以查看实现、提出改进。
零成本。工具完全免费，没有付费墙，也没有功能阉割版。
为谁而做
无论你是需要快速导出图标的独立开发者、想给博客配一套 favicon 的站长、做原型的设计师，还是只想把手机照片压小一点的普通用户——cataito 都希望成为你浏览器书签里那个「随手就能用」的工具箱。
开源与透明
我们相信工具应当可被审视。cataito 的全部源码开放在 GitHub 仓库，欢迎提交 Issue 与 Pull Request。如果你想了解更多或提出合作，请前往联系我们页面。
What we do
cataito is a collection of free online tools for developers, designers, and everyday users. We turn frequent, lightweight needs—icon generation, image compression, color extraction—into web tools you can use the moment you open them. No account, no installation: just open your browser and go.
Our core principle is privacy first: every image and file is processed locally in your browser and is never uploaded to our servers. Your assets stay yours.
Our tools
IconForge Studio: upload one image and generate multi-size .ico / .png app icons and favicons, with light and dark variants.
Favicon Generator: one-click multi-size favicon packs covering common desktop and mobile sizes.
Image Compressor: shrink PNG / JPEG / WebP with barely perceptible quality loss to speed up web pages.
Palette Tool: extract color schemes from an image or a keyword to get a ready-to-use palette.
Our principles
Local processing. All computation happens in your browser; files are never uploaded or stored.
No tracking, no account. We run no third-party tracking cookies and require no login. Use it and leave.
Open source. The entire site is hosted publicly on GitHub; anyone can inspect the implementation and suggest improvements.
Zero cost. Tools are completely free—no paywall, no crippled trial tier.
Who it's for
Whether you're an indie developer who needs a quick icon export, a blogger setting up favicons, a designer prototyping, or just someone shrinking a phone photo—cataito aims to be the "grab-and-go" toolkit in your bookmarks.
Open and transparent
We believe tools should be inspectable. All cataito source lives in our GitHub repository; Issues and Pull Requests are welcome. To learn more or propose collaboration, visit our Contact page.
