Image to ICO converter vs. typical online converters
Most image-to-ICO sites convert one size at a time, require an account, or push you to a paid download. This one builds a single .ico that already contains every size Windows and browsers ask for.

Frequently Asked Questions
Upload a PNG, JPG, WebP or SVG, tick the icon sizes you need, and click generate — the multi-resolution .ico downloads immediately. The conversion runs in your browser, so the image is never uploaded.
ICO is the icon container format Windows uses. One .ico file can hold several images at different sizes (16×16, 32×32, 256×256 and so on), and Windows picks the best one for the taskbar, desktop or file explorer view. The same file also works as a website favicon.
Yes — PNG, JPG/JPEG, WebP and SVG all work as input. PNG with a transparent background gives the cleanest result, because the transparency is kept in every size.
You choose. Available sizes are 16, 24, 32, 48, 64, 96, 128, 256 and 512 pixels; the default set is 16, 32, 48, 64, 128 and 256. Every selected size is embedded as a full PNG payload inside the single .ico container.
No. Everything runs in your browser with the Canvas API and JavaScript. Your images never leave your device, and there is no tracking of the file itself.
No watermark, no export limit and no paid unlock. The .ico you download is a clean file you can ship in an app, a website or a Windows folder right away.
Favicon Generator is for the web: fixed sizes plus an HTML snippet and a PWA manifest. ICO Icon Generator is for desktop and app icons, where you pick custom sizes and get a single .ico. Both are free and both run locally.
Smooth (bilinear) suits photos and gradients. Crisp (nearest neighbour) keeps pixel art sharp. High quality is the default and is the safest choice for most icons.
Windows and web browsers require .ico format for website favicons and application icons — regular PNG files won't show up as the tab icon or desktop shortcut icon on older Windows versions. Most online ICO converters force you to sign up, pay a subscription, or watermark your exported icon file. Our free ICO generator converts any PNG/JPG/WEBP image into a multi-resolution .ico file directly in your browser, with no upload to external servers.
The generated ICO includes all standard icon sizes browsers and Windows need: 16x16 for browser tabs, 32x32 for desktop shortcuts, 48x48 for large icon views, and 256x256 for high-DPI displays. One exported file works everywhere — you don't need to manually create and pack multiple resolutions into the icon container yourself. Just drag and drop your logo, click generate, and download the ready-to-use .ico file.
When You Need an ICO File
The most common use case is setting up your website favicon: after deploying the .ico file to your website root, add a single line of code to your HTML head and browsers will show your logo in the tab, bookmarks bar, and history list. You also need .ico files for Windows application installers, desktop shortcuts for your own web apps, and custom folder icons in Windows Explorer. The generator works for both personal projects and commercial use — there's no licensing restriction on the exported files.
Tips for Best ICO Results
Start with a square source image — non-square photos will get auto-cropped to a square, which can cut off important parts of your logo. Keep the core of your design centered: the 16x16 browser tab size is tiny, so any text or fine detail near the edges will disappear when scaled down. If your logo has transparent background, keep it transparent — ICO files support alpha channels, and transparent favicons look far cleaner on dark mode browser themes.
Since all conversion runs locally in your browser, your logo files never get sent to a remote server. That's important for brand assets you don't want sitting on random conversion tool servers somewhere. There's no file size limit, no daily conversion cap, and no watermark on the exported .ico. You can convert as many icons as you need for free, forever. If you need multiple icon sizes for different platforms, you can also use our image resizer first to prepare your source image before converting to ICO format.
We don't keep copies of any uploaded images, so your brand assets stay completely private and secure.
