How to use Favicon Generator
- 1
Open the Favicon Generator
Go to tools.slaytic.com and open the Favicon Generator. No sign-up or account required.
- 2
Upload your logo
Drop a square logo onto the tool, or click to browse and select it. The image is processed in your browser and never uploaded to a server.
- 3
Style and preview
Optionally add a background colour, margins and corner radius, set your theme colour and path prefix, then check the live browser-tab, search-result and home-screen mockups.
- 4
Download the ZIP
Download one ZIP containing favicon.ico, every PNG size, the Apple touch icon, site.webmanifest and a snippet.html with the exact tags to paste into your head.
How this works in your browser
Everything is generated in your browser. Your logo is drawn onto an HTML5 canvas once per required size, letting the browser resample it down to each dimension, and each canvas is exported as a PNG. The .ico file is assembled by hand in JavaScript: an ICONDIR header plus one directory entry per embedded size, with the 16, 32 and 48px PNGs packed in as PNG-in-ICO, which is what lets a single favicon.ico carry several resolutions. The manifest and HTML snippet are generated as text from your chosen theme colour and path prefix, and JSZip bundles the whole set into one download without any of it touching a server.

Who uses Favicon Generator
Launching a new site
Produce every favicon size a modern site is expected to ship, plus the manifest and link tags, in one step instead of exporting sizes by hand.
Fixing a blurry or missing tab icon
Replace a single low-resolution favicon with a full multi-size set so the icon stays sharp on high-DPI screens and in search results.
Adding home-screen icons
Generate the Apple touch icon and Android 192/512px icons needed for a site to look right when saved to a phone home screen.
Frequently asked questions
What does the ZIP package include?
favicon.ico (16, 32, and 48px bundled), favicon-16x16/32x32/96x96.png, apple-touch-icon.png (180px), android-chrome-192x192.png and 512x512.png, a site.webmanifest, and a snippet.html with the exact link tags to paste into your head.
Does my source image need to be square?
A square image gives the cleanest result. Non-square images are cropped to a centred square before resizing, and the "Add background & margins" style can pad any logo into a clean square tile.
What is the Favicon Path setting for?
It is the URL prefix used in the generated snippet and manifest. Keep the default / if you upload the files to your site root, or set something like /wp-content/uploads/ if they live in a subfolder.
Are the previews accurate?
They are close visual mockups of how the icon renders in browser tabs, Google results, and phone home screens - final rendering can vary slightly per browser and device.
Why is my favicon not showing after I uploaded the files?
Almost always caching. Browsers hold onto favicons unusually aggressively, well beyond a normal page refresh, so the old icon or a blank one persists. A hard refresh, a private window, or appending a version query string to the icon URL are the three reliable ways to confirm the new file is actually being served.
Will my detailed logo work at 16 pixels?
Probably not intact, which is worth checking in the preview before you ship it. At 16 pixels there is room for a bold shape and essentially nothing else, so fine lines, gradients and any text turn to mush. Many brands use a simplified mark or a single letter for the favicon rather than the full logo.
Do I still need favicon.ico if I have PNGs?
Yes, keep it. Browsers request /favicon.ico from the site root automatically even without a link tag, and some older software looks for nothing else. The ICO costs almost nothing and covers the fallback case that the PNG link tags do not.
Is my logo uploaded anywhere?
No. Every size is rendered, the ICO assembled and the ZIP packed inside your browser tab, so unreleased branding never reaches a server.
