SaveImageConvert PNG to ICO
Free PNG to ICO converter that runs entirely in your browser — private, fast, with no daily quota. No signup, no watermark.
Turns a PNG into a favicon.ico with multiple sizes in one file — 16, 32 and 48 px by default, up to 256. Browsers pick the sharpest size automatically, so a multi-size ICO looks crisp in tabs, bookmarks and the Windows taskbar alike. Square logos with transparency work best.
PNG to ICO: what changes

- Transparency

- Best for
- favicons, browser tabs, bookmarks and Windows shortcuts
- Animation & metadata
- This tool creates a still image; it does not add animation to the output. The new file may not retain the source file's EXIF metadata.
