Favicon Generator

A blurry or missing favicon is one of the more noticeable signs of an unfinished site, and modern browsers and devices expect a small set of specific icon sizes, not just one .ico file. This tool takes a source image and redraws it at each required size directly on an HTML canvas in your browser, then packages the results for download — no logo upload required. See What's Hiding in Your Photos for more on how canvas-based center-cropping keeps a non-square logo from distorting.

The Advantage of Local Icon Generation

Most online "favicon makers" require you to upload your high-resolution logo or SVG to their servers, where it may be stored, analyzed, or leaked. Our Zero-Storage architecture eliminates this privacy risk. By using high-performance client-side JavaScript (powered by the jszip and Canvas APIs), we slice, resize, and package your icons directly on your device.

• Ideal for working on confidential brand identities, unreleased product logos, and internal company portals.
• Watch how your logo translates into various sizes—from the tiny 16x16 browser tab icon to the high-res 512x512 Android splash—in real-time.
• The bundle includes a favicon.ico file for legacy compatibility — note that it's a 32×32 PNG image saved with the .ico extension, not a true multi-resolution ICO container (embedding several sizes into one authentic .ico binary isn't done by this tool). Every modern browser accepts this form fine; if you specifically need a real multi-size .ico for a Windows desktop shortcut or similar, use a dedicated ICO tool for that step.
• Your brand assets never leave your browser, ensuring compliance with strict corporate IT security policies and data protection laws.

Decoding the Icon Suite: What's Included?

A modern icon bundle requires more than just one file to be fully compliant with today's browsers and operating systems:

• The classic multi-resolution file required for backward compatibility with legacy browsers and bookmarks.
• A high-resolution 180x180 icon specifically used by iOS devices when a user adds your website to their Home Screen.
• High-fidelity icons used by Chrome on Android and for Progressive Web App (PWA) splash screens.
• A JSON file that tells Android devices how to display your "app" (including its name, theme colors, and icon paths).

How to Generate Your Icon Bundle (Step-by-Step)

Our interface is designed for surgical precision and ease of deployment:

1. Drag and drop your high-resolution PNG, SVG, or JPG into the uploader area above. SVG is highly recommended for the sharpest results across all sizes.
2. Our tool will instantly generate previews for all major sizes and platforms. Check that your logo remains recognizable even at 16x16.
3. Click the "Generate Icon Bundle" button. The engine renders your logo at 5 distinct sizes (16, 32, 180, 192, and 512px) across the bundle's files and zips them together in your browser's RAM.
4. Your newly created .zip bundle is ready for download instantly. No waiting for server-side processing or email delivery.

Strategic Use Cases for Icon Generation

• Generate all the standardized assets required to pass "Add to Home Screen" audits in Google Lighthouse and Chrome.
• Ensure that your company's logo looks sharp and consistent whether it's pinned to a Windows Taskbar or a Safari tab.
• Quickly generate icons for "coming soon" pages or internal staging environments without opening complex design software like Photoshop or Figma.
• A missing favicon is a major red flag for users and search engines. Adding a proper icon suite improves "at-a-glance" trust and reduces bounce rates from browser tabs.

Frequently Asked Questions

Which image formats are supported?

Our generator works best with SVG (for infinite scalability) or high-resolution PNG files with transparency. It also supports JPG and WebP for standard logo uploads.

What files are included in the bundle?

The generated .zip includes: favicon-16x16.png, favicon-32x32.png, favicon.ico (a 32×32 PNG saved with the .ico extension, not a true multi-resolution ICO — see above), apple-touch-icon.png (180×180), android-chrome-192x192.png, android-chrome-512x512.png, and the site.webmanifest file — plus an instructions.html with the <link> tags to copy into your page's <head>. Each of the 5 sections (ICO, PNG, Apple, Android, Manifest) has its own checkbox and can be toggled off individually before generating if you don't need all of them.

Does this tool send my logo to any server?

Absolutely none. In accordance with our Zero-Storage architecture, the entire generation and zipping process occurs within your browser's local memory. Your private brand assets and unreleased logos are never uploaded or logged.

How do I install the icons?

Extract the .zip contents into your website's root (public) folder and copy the <link> tags into the <head> of your HTML document. The bundle includes an instructions.html file (not a .txt) with the exact snippet to copy — it's only generated if the "Manifest" section is checked.

Why not just use a single 32x32 PNG?

Modern devices have very high pixel densities (Retina, 4K). A single small PNG will look blurry on these screens. Our bundle provides high-resolution alternatives that the browser will automatically select to ensure your brand looks sharp on every device.

My source logo isn't square — will the icons look stretched?

No. Every size in the bundle is square, so a non-square source is center-cropped to a square region first (the largest square that fits, taken from the middle of the image) and then scaled — never stretched. If your logo has important detail near the left/right or top/bottom edges of a wide or tall image, crop it to square yourself beforehand so nothing important falls outside that center region.
