About these image formats
What is PNG?
PNG (Portable Network Graphics) is a lossless raster format that supports transparency. It is ideal for logos, icons, screenshots, and graphics that need sharp edges.
How to open: PNG files open natively in all browsers and operating systems. They are the standard format for web graphics with transparent backgrounds.
Best for: Use PNG when you need transparency, lossless quality, or crisp text and line art.
What is ICO?
ICO is the Windows icon format. ICO files can contain multiple resolutions (16×16 to 256×256) in a single file for favicons and app icons.
How to open: ICO files open in image editors and are used directly as website favicons and Windows application icons.
Best for: Convert PNG or JPG to ICO to create favicons with multiple embedded sizes for browsers and Windows.
FAQ
Frequently asked questions
Are my files uploaded to a server?
No. ImageConverter runs entirely in your browser. Your files never leave your device — you can verify this in your browser's network tab.
Is PNG to ICO conversion free?
Yes. ImageConverter is free with no signup, no watermarks, and no file limits beyond your device's memory.
Can I use this to make a favicon?
Yes. ICO is the classic favicon format. Start from a square PNG — 256×256 or larger — and the converter writes the standard icon sizes into a single .ico file.
Is PNG transparency kept in the ICO?
Yes. ICO supports an alpha channel, so transparent PNG backgrounds stay transparent in the icon.
Can I convert multiple PNG files at once?
Yes. Add multiple files and convert them in one batch. Each converted ICO file can be downloaded individually.
Which browsers are supported?
ImageConverter works in Chrome, Firefox, Safari, and Edge. WebP output requires a modern browser with WebP encoding support.
