Generate a favicon.

Turn a logo or image into a complete favicon package — favicon.ico, Apple touch icon and Android icons, plus the HTML to paste in — without a single file leaving your device.

Not uploaded — nobody sees it Real multi-size .ico file Full icon set + manifest No subscription or account
Your file is never uploaded — it’s processed right here in this browser tab, on your device. There’s no server involved, so we never see it, copy it or keep it.
How it works

Three steps, no waiting on a server

Altto's favicon generator works right in your browser tab using the canvas built into every modern browser, so there's no upload queue and no “processing your file” spinner tied to someone else's servers.

01

Add your logo or image

Any shape works — it’s centre-cropped to a square automatically.

02

Preview every size

See it as a browser tab icon and bookmark before you download.

03

Download the package

A .zip with favicon.ico, app icons and the HTML to paste in.

Why this runs in your browser, not on a server

Your logo is your brand — not something you'd want sitting on a stranger's server just to resize it a few times. Altto skips that step completely — there's no server for it to go to.

  • Nothing is uploaded, everEvery size is generated by code that runs in this browser tab, because there’s no server on the other end. That also means we can’t see it, copy it or keep it.
  • No account, no email wallGenerate as many favicon packages as you like without signing up or handing over an email address.
  • The complete standard setfavicon.ico, both PNG sizes, Apple touch icon, both Android sizes and a web manifest — not just one lonely .ico file.

logos stored on our servers. There’s no server involved at all — each icon set is built once, locally, on your device.

FAQ

Frequently asked questions

The practical details on what this tool can and can’t do. Need to resize an image first? See Image Resize.

What files do I actually get?
A .zip with everything a website needs: favicon.ico (a proper multi-resolution icon embedding 16×16, 32×32 and 48×48), favicon-16x16.png, favicon-32x32.png, apple-touch-icon.png (180×180, for iOS home-screen icons), android-chrome-192x192.png and -512x512.png, and a ready-made site.webmanifest. Unzip it into your site's root folder.
What do I do with the HTML snippet?
Paste the five lines shown after you generate your icons into the <head> of every page on your site, right after your other <meta> tags. That's what tells browsers, phones and search engines where to find each icon.
My image isn't square — what happens to it?
It's automatically centre-cropped to a square before anything else, the same way a phone camera crops a photo to fit a square frame. For the cleanest result, start with an image where the important part of your logo is already centred.
Is a real .ico file actually built, or just a renamed PNG?
A real one. favicon.ico is built byte-for-byte in your browser as a proper multi-resolution icon container holding all three sizes, not a single image with the extension changed — the same format every operating system and browser expects.
Is my image uploaded anywhere?
No — nothing is ever uploaded. Every size is generated entirely inside this browser tab using the canvas built into your browser. There's no server involved at all, so there's nothing for Altto to see, copy or keep.
Do you keep a copy of my image?
No. There's no upload, so there's nothing on our side to keep. See the Privacy Policy for details.
