About converting PNG to ICO
This free PNG to ICO converter runs entirely in your browser. Drop one or more PNG files, adjust quality if available, and download ICO copies — your images never leave this device.
PNG is commonly used for logos and icons. ICO is a better fit when you need website favicons or app icons. Converting locally means no upload queues, no account, and no third party can see your files.
When to use ICO instead of PNG
Switch from PNG to ICO when the destination app, website, or workflow prefers ICO, or when ICO gives you a clearer quality or size trade-off for your use case.
- ICO: Standard favicon format for browsers
- ICO: Can embed multiple sizes in one file
- ICO: Works with Windows shortcuts and browser tabs
- PNG limitation: Larger files than JPG or WebP for photos
- PNG limitation: No built-in photo-style lossy compression
How to convert PNG to ICO privately
Upload is never required. Everything uses your browser’s image decoder and canvas encoder.
- Choose PNG files (or drag them onto the drop zone).
- Set quality if the ICO format supports lossy encoding.
- Click Convert — processing happens on your device.
- Download each result, or download all when converting a batch.
PNG vs ICO: quick comparison
PNG strengths include lossless quality and full transparency support. ICO stands out for standard favicon format for browsers and can embed multiple sizes in one file.
If you still need PNG later, keep a master copy. Lossy formats like JPG and some WebP exports cannot recover detail that was discarded during encoding.
Tips for better results
A few practical habits help you keep quality high and files small.
- Start from the highest-quality source you have — never convert from a heavily compressed preview if you can avoid it.
- For photos, try WebP or JPG around 80–90% quality before going lower.
- For logos and screenshots, prefer PNG or lossless WebP so text stays sharp.
- Resize before compressing if you only need a small display size — fewer pixels usually beat aggressive quality cuts.
