Upload an image to automatically generate multi-size ICO icons (16/32/48/64/128/256) plus favicon and apple-touch-icon PNGs in various sizes, with a ready-to-use header.html code and a downloadable ZIP, so your site shows a full custom icon when added to the home screen or bookmarks
Features
The Image to ICO Icon tool turns any image into the multi-size icons your website needs. After you upload an image, it automatically generates:
- favicon.ico: a single ICO file packing six common sizes (16/32/48/64/128/256), compatible with all major browsers
- favicon images: three PNGs at 64x64, 128x128, and 192x192
- apple-touch-icon images: four PNGs at 76x76, 120x120, 152x152, and 180x180 for iOS home screen icons
- header.html code: complete markup including each icon reference and the
<link rel="shortcut icon"> tag, ready to copy
- ZIP download: favicon.ico and all PNGs bundled into one archive for one-click download
With this code in place, adding your site to a browser home screen, bookmarks, or the taskbar shows the full custom icon instead of the browser default icon with a small thumbnail.
How It Works
After the image is uploaded, the tool automatically validates its format (PNG, JPG, GIF, WEBP, and BMP are supported), center-crops it to a square using the shorter side, and scales it at high quality to produce each target size. The whole process runs entirely on the backend, with no manual steps required.
The ICO file uses the modern container format (ICONDIR + one ICONDIRENTRY per size + embedded PNG data), so the crisp 256px PNG can be stored losslessly inside the ICO file. Every PNG keeps its alpha transparency channel, ideal for rounded, circular, or irregular icon shapes.
Finally, all generated files (favicon.ico and every PNG) are compressed into a single ZIP archive for one-click download and deployment.
Use Cases
- Site launch: prepare a favicon and iOS home screen icon for your website
- Brand consistency: generate a matching set of icons in every size from your logo
- Mobile experience: added-to-home-screen sites show the full custom icon, boosting recognition
- Quick deployment: download favicon.ico and every PNG at once and drop them into your site root
FAQ
- Q: Which image formats are supported?
- A: PNG, JPG, GIF, WEBP, and BMP. A transparent-background PNG is recommended so rounded or irregular shapes keep their transparency.
- Q: What if the image is not square?
- A: The tool center-crops it to a square based on the shorter side before resizing, avoiding distortion.
- Q: Which sizes are packed into the ICO?
- A: The favicon.ico bundles six sizes - 16, 32, 48, 64, 128, and 256 - covering everything from a small address-bar icon to a large high-resolution one.
- Q: How do I use these files on my site?
- A: Place favicon.ico in your site root, put the PNGs from the favicon/ folder in the matching paths, then copy the generated header.html code into your page's <head>.
- Q: Why does the home screen show the full icon?
- A: Because the apple-touch-icon (dedicated to iOS home screens) and complete favicon references are provided, the system uses the custom icon directly instead of falling back to the browser icon plus a page thumbnail.
Examples
Turn a logo into a full set of site icons:
- Click or drag to upload a logo (preferably square, transparent PNG)
- Wait for generation, then click "Download ZIP" to get favicon.ico and all PNGs
- Put favicon.ico in your site root and place each PNG in the favicon/ folder
- Copy the generated header.html code into your page's <head> and save
The generated header.html code looks like:
<link rel="icon shortcut" href="/favicon/64x64.png" sizes="64x64">
<link rel="apple-touch-icon" href="/favicon/180x180.png" sizes="180x180">
<link rel="shortcut icon" href="/favicon.ico" type="image/x-icon" />
Related Tools
This tool belongs with the design family together with Image Color Picker, Color Palette, and Color Converter: the color picker samples colors from images, the palette builds gradient shades from a single color, the converter swaps colors between models, and this tool turns an image into site icons. When building and deploying a site, it is often used alongside Base64 Encode and ASCII Lookup.
