How to convert ICO to PNG
- Drag your ICO files into the box above or click “Choose files” (folders and pasting from the clipboard work too).
- PNG is preselected as the output format; adjust quality, size and target file size if you like.
- Press “Start converting”; files are converted in your browser, in parallel.
- Download the files one by one or grab them all as a ZIP.
Why convert ICO to PNG?
PNG is lossless: it does not lose quality on every save and it keeps transparency. It suits logos, screenshots and images you plan to edit later.
ICO files are read by your browser and the icon inside is converted to an image.
ICO vs PNG
| ICO | PNG | |
|---|---|---|
| File extension | .ico | .png |
| Compression | Lossless | Lossless |
| Transparency | Yes | Yes |
| Animation | No | No |
| Typical file size | Small | Large (for photos) |
| Support | Windows and browsers | Everywhere |
| Best for | favicons, Windows application icons | logos, screenshots, icons, graphics with transparent backgrounds |
ICO is the format used for Windows icons and website favicons; one file can hold several sizes. PNG is a lossless format with full transparency (an alpha channel). File sizes get large for photographs, and animation support is not widespread.
Tips for the best results
- To shrink the file further tick “Best compression”; it is slightly slower but still lossless.
- For the web, limiting the width to 1600 pixels cuts file size a lot while keeping visual quality (Resize section).
- Metadata such as GPS location and camera details (EXIF) is always removed from the output.
Privacy and security
Conversion runs entirely in your browser (using WebAssembly); your images are never uploaded to our server and never leave your device. The server only receives anonymous counters that contain no file names or content (source/target format, size, duration). Metadata such as location and camera details is always stripped from the output.
