A complete favicon set, made in your browser.
Iconvanta is being built to turn text, an emoji or an image into every icon a website needs, with no account and no upload. The site is live and the generator is on its way: nothing here makes an icon yet.
What a complete icon set contains
This is the set the generator is being built to produce. It is useful to know on its own, whichever tool you use to make the files.
| File | Size | What it is for |
|---|---|---|
| favicon.ico | 16, 32 and 48 px | The long-standing format. One file can hold several sizes, and browsers ask for /favicon.ico by default when a page names no icon. |
| favicon-16x16.png | 16 × 16 px | The smallest size shown in a browser tab. |
| favicon-32x32.png | 32 × 32 px | A sharper tab icon for denser screens and for browser toolbars and shortcuts. |
| apple-touch-icon.png | 180 × 180 px | The icon iOS uses when a page is added to the home screen. iOS rounds the corners itself and does not keep transparency, so it should be a full square. |
| android-chrome-192x192.png | 192 × 192 px | Listed in the web app manifest, for the home screen on Android and for installed web apps. |
| android-chrome-512x512.png | 512 × 512 px | Listed in the web app manifest, for splash screens and the large size an installable web app needs. |
| site.webmanifest | Any size | A small JSON file that names the site and points to its icons, so that an installed web app has a name, an icon and a theme color. |
| favicon.svg | Any size | A scalable icon that stays sharp at every size. Most current browsers use it, but not all, so it complements the other files instead of replacing them. |
How the icons will be made
Your browser can already do all of it. It opens the image, draws it on a canvas at each size, and encodes each drawing as a PNG. An ICO file is a small container that can hold those PNGs, and a ZIP file is a container for the finished files, so both can be written without a server.
The generator will offer a file only when it can really produce it, and will say so when it cannot, for example when a browser cannot open a particular image format. A file too large or too small to make a good icon will be reported, with the reason, instead of being silently shrunk.
Where things stand
The site, its pages and its privacy policy are in place. The generator is not. That is why this page says so instead of showing an upload button that does nothing. When the first tool is ready it will have its own page with a guide, an example and answers to common questions, and it will be added to this page.
Meanwhile, read how the site treats your data in the privacy policy, or tell us which tool you need first through the contact page.
Questions
Can I generate a favicon with Iconvanta today?
Not yet. The site is live, but the generator and its tools are still being built, and this page lists them as planned. Nothing here makes an icon at the moment.
Will my image be uploaded?
The tools are being designed so that it is not. They will open your image, draw the icons and pack the files in your browser, which is why Iconvanta needs no account and no server step. The privacy policy says what is true today, and will say what each tool does when it is added.
Which of these files does my site actually need?
A small site can start with a favicon.ico or a 32 pixel PNG, an Apple touch icon, and the two Android icons listed in a web app manifest. The SVG is a useful extra for browsers that use it. The table above says what each file is for, so you can leave out what your site does not need.
Why does my old favicon still show after I change it?
Browsers keep favicons in a cache of their own that is separate from the page, so an old icon can stay for a while. Changing the file name or adding a version to its address in the page, and reloading the page without the cache, usually brings the new one.
