A favicon generator takes one image and turns it into the full set of small icon files that browsers, phones, and operating systems use to represent your website β the tiny logo in a browser tab, the icon on an Android home screen, the shortcut tile on Windows. This tool does that job entirely inside your browser: pick an image, click generate, and download every size you need without ever sending the file to a server.
We built this favicon generator as part of Arb Digital's free tools collection because we noticed how often a favicon gets forgotten during a website launch. It's a small detail, but a missing or blurry favicon quietly signals "unfinished" to every visitor who glances at their tab bar, and it is one of the fastest, cheapest branding wins available to any site owner.
What This Favicon Generator Does
Upload any image β a logo, a wordmark, a simple icon, even a photo β and the tool draws it onto a hidden canvas element, crops it to a perfect square from the center, and re-renders that square at seven standard sizes: 16Γ16, 32Γ32, 48Γ48, 96Γ96, 180Γ180 (the Apple touch icon size), 192Γ192, and 512Γ512 pixels. Each size gets its own download button so you can save exactly the files your site needs. The tool also writes out a ready-to-paste HTML snippet for your page's <head> section and a matching site.webmanifest JSON file, which modern browsers use to understand your icon set for "Add to Home Screen" and progressive web app behavior.
Because everything runs with JavaScript's Canvas 2D API directly in your browser, there is no upload step, no waiting on a server queue, and no risk of your unreleased logo or private brand asset ever leaving your device. You could disconnect from the internet after the page loads and the favicon generator would keep working.
How to Use It
- Choose your source image. Click the upload field or drag and drop a PNG, JPG, or WEBP file onto the drop zone. A square image with the subject centered gives the cleanest result, since the tool crops to a square automatically.
- Preview the crop. The canvas preview shows exactly what will be turned into your favicon set, so you can confirm nothing important got cropped off the edges.
- Click "Generate All Favicon Sizes." The tool instantly renders all seven sizes and unlocks the download buttons along with the HTML snippet and manifest file.
- Download each PNG and place them in your website's root or an
/icons/folder, matching whatever paths you use in the snippet below. - Paste the HTML snippet into the
<head>of every page template (or your CMS's global header settings) so browsers can find the right icon automatically. - Save the site.webmanifest file to your site root and link it from the head snippet β this powers Android "Add to Home Screen" prompts and basic PWA icon behavior.
How the Sizes Are Generated
Under the hood, the generator loads your image into an HTML <img> element, then for each target size it creates a new in-memory <canvas>, calculates a centered square crop based on whichever dimension of your source image is smaller, and calls drawImage() to scale that square crop down (or up) to fit the target pixel size exactly. Finally it calls canvas.toBlob() to produce a real PNG file in memory, wraps it in an object URL with URL.createObjectURL(), and attaches that URL to a download link. According to MDN's documentation on the link element, browsers will pick whichever declared icon size best matches the context β tab, bookmark bar, or home screen β which is exactly why having several sizes available matters more than shipping just one.
One honest limitation: the classic Windows .ico format can bundle multiple resolutions inside a single container file, and producing a true multi-resolution .ico requires a binary-packing library that goes beyond what a browser's Canvas API can do on its own. Rather than fake it, this tool gives you individual PNG files at every standard size instead. Every modern browser β Chrome, Firefox, Safari, Edge β happily reads PNG favicons declared via <link rel="icon" type="image/png">, so in practice you lose nothing by skipping the legacy .ico wrapper.
Why Favicons Matter for Branding
A favicon is one of the smallest pieces of digital real estate a brand owns, and also one of the most frequently seen. Every open tab, every browser bookmark, every entry in a "recently visited" list carries that tiny icon. When it's missing, browsers substitute a generic blank-page glyph, which makes a site look abandoned or untrustworthy even if the rest of the page is polished. When it's present and recognizable, it reinforces brand recall every single time a visitor glances across a crowded tab bar looking for your site among a dozen others.
Favicons also show up in less obvious places: browser history and autocomplete suggestions, RSS readers, some search engine result snippets, social sharing previews on certain platforms, and the icon grid when a user pins your site to their phone's home screen. A blurry, stretched, or off-center favicon undermines all of those touchpoints at once, while a crisp one generated at the correct pixel dimensions looks intentional everywhere it appears.
Which Sizes You Actually Need
Not every project needs all seven sizes, but covering them removes any guesswork. The 16Γ16 and 32Γ32 pixel versions cover standard desktop browser tabs and the Windows taskbar. The 48Γ48 size is used by Windows for desktop site shortcuts. The 96Γ96 size covers larger desktop icon contexts and some older Android launchers. The 180Γ180 "Apple touch icon" size is what iOS uses when a visitor adds your site to their iPhone or iPad home screen β get this one wrong and Apple devices will show a low-resolution, blurry icon. The 192Γ192 and 512Γ512 sizes are the modern Android and progressive web app standard, referenced from the site.webmanifest file this tool generates for you, and the 512Γ512 size doubles as the splash-screen icon on some platforms.
- 16Γ16 / 32Γ32: desktop browser tabs, bookmarks, taskbar pins.
- 48Γ48: Windows desktop shortcuts and some legacy contexts.
- 96Γ96: larger desktop icon grids.
- 180Γ180: Apple touch icon for iOS home screen and Safari.
- 192Γ192 / 512Γ512: Android home screen, Chrome "Install app," and PWA manifests.
Design Tips for a Favicon That Actually Reads at 16px
Most favicon failures aren't technical β they're design failures that only become visible once you shrink a detailed logo down to the size of a grain of rice. A wordmark with three words in a thin font will turn into an unreadable smudge at 16Γ16 pixels. The fix is to design (or crop) a simplified mark specifically for this purpose: a single letter, a simple geometric symbol, or the boldest element of your logo, rendered with strong contrast against its background and generous internal padding so it doesn't touch the edges of the square. Test the 16Γ16 download in an actual browser tab before finalizing β that is the harshest, smallest, and most-seen size of the whole set, so if it looks good there, every larger size will look even better.
Color contrast matters as much as shape. A pale gray icon on a white background disappears in a browser's light-mode tab bar, and a dark icon can vanish just as easily in dark mode. Favor a bold, saturated color or a color that reads clearly against both light and dark UI chrome. If your brand mark relies on subtle gradients or fine detail, simplify it for the favicon rather than trying to force the full logo into 16 pixels.

Our Web Design Services All Free ToolsCommon Mistakes to Avoid
- Uploading a non-square image without checking the crop. The tool center-crops automatically, but if your logo isn't centered in the source file, important detail can get cut off β check the preview before generating.
- Only using one size. A single 32Γ32 icon stretched up by the operating system for a 512Γ512 home-screen slot will look pixelated; generate and use the full set instead.
- Forgetting the Apple touch icon. Without a 180Γ180 icon declared, iOS falls back to a screenshot of your page as the home-screen icon, which almost never looks intentional.
- Skipping the site.webmanifest link. Android's "Add to Home Screen" and Chrome's "Install app" prompt rely on the manifest file to find your 192px and 512px icons β without it, they may not offer to install your site at all.
- Caching issues after replacing a favicon. Browsers aggressively cache favicons; after uploading new files, a hard refresh (or a versioned filename like
favicon.png?v=2) is often needed before visitors see the update. - Using a low-resolution or heavily compressed source image. Upscaling a blurry 100Γ100 logo to 512Γ512 will only produce a bigger blurry icon β start from the highest-quality source you have.

Frequently Asked Questions
Yes. There is no account, no email capture, and no watermark. Upload an image, generate your sizes, and download as many times as you like.
No. This tool runs entirely in your browser using the Canvas 2D API. Your image is read locally, processed locally, and the resulting PNG files are generated locally β nothing is ever transmitted anywhere.
A true multi-resolution .ico file packs several image sizes into one binary container, which requires a dedicated packing library rather than pure Canvas drawing. Instead, this tool outputs individual PNG files at every standard size, which every modern browser supports directly via the HTML link tag.
PNG, JPG, and WEBP all work well. PNG is ideal if your source logo has transparency, since the generated favicons preserve any transparent background.
Browsers cache favicons aggressively, sometimes for days. Try a hard refresh, clear the site's cached data, or append a version query string like favicon.png?v=2 to force browsers to fetch the new file.
You can use as few or as many as you need, but including the full set ensures your icon looks sharp in every context β browser tabs, Windows shortcuts, iOS home screens, and Android/PWA installs β rather than relying on the operating system to stretch a single size.
This tool runs entirely in your browser using built-in JavaScript. Your images are never uploaded, stored, or sent to any server.
