A square image works best — non-square images will be centre-croppedWhere you'll actually use an ICO file
ICO is the format Windows uses for desktop shortcuts, taskbar icons, and application icons in File Explorer. Browsers also still fall back to favicon.ico in a site's root folder for older bookmarking behaviour, even though most modern favicon setups mainly rely on PNG files declared in the page's HTML. If you need a full favicon set rather than a single icon, our favicon generator builds all the common sizes at once.
How to use Convert PNG to ICO
- Upload the file you want to convert using the upload box above.
- The tool reads the file and converts it automatically — no extra settings to fill in for most conversions.
- Preview the converted result shown on screen.
- Download the converted file, ready to use anywhere the original format wasn't accepted.
Tips for best results
- Keep your original file until you've confirmed the converted version opens correctly wherever you need it.
- If a converted file looks wrong, double-check your browser actually supports decoding the source format (this matters most for newer formats like HEIC and AVIF).
- Batch conversions go faster if your source photos are a similar size — very large files take longer to process.
❓ Frequently asked questions
Is there a watermark on the converted file?
No — the output is a clean file with no watermark or branding added.
Does this work offline?
The page itself needs to load once from the internet, but the conversion itself happens locally in your browser without needing an ongoing connection.
Why does my icon look cropped?
ICO files are square. If you upload a rectangular image, this tool centre-crops it to a square before resizing, so keep your logo's important content near the middle.
What size should I pick?
32×32 is the standard, safest choice for a general-purpose favicon or icon. Use 256×256 if the icon needs to look sharp at a larger display size, like a Windows desktop shortcut.
Does this ICO file work on both Windows and browsers?
Yes — this tool creates a standard single-image ICO container that both Windows and web browsers recognise correctly.
