Frequently Asked Questions
ChangeThisFile automatically selects the highest resolution icon from the ICO file. Most ICO files contain multiple sizes (16x16, 32x32, 48x48, etc.) and we extract the largest available size to give you the best quality PNG.
Yes. Both ICO and PNG formats support alpha channel transparency. The transparent areas in your ICO icon will be perfectly preserved in the converted PNG file.
Yes, but only one PNG is generated per ICO file. We extract the highest quality icon from the ICO and save it as PNG. If you need multiple sizes, you would need to use specialized icon extraction software.
No. ChangeThisFile converts files entirely in your browser using JavaScript. Your ICO files never leave your device, making this the most private way to convert icons.
ICO files are primarily used for Windows applications and website favicons. PNG is more widely supported across platforms, software, and web browsers. Convert when you need to use an icon in documentation, presentations, or modern web applications.
Yes. You can drop multiple ICO files at once and they will all be converted to PNG simultaneously. Each file is processed independently in your browser.
Yes. ChangeThisFile works in any modern mobile browser including Safari on iOS and Chrome on Android. No app installation needed.
There is no quality loss since both ICO and PNG use lossless compression. The conversion extracts the raw pixel data from the ICO and saves it as PNG without any recompression.
ICO files don't support animation, but if you have an animated cursor file (ANI), only the first frame would be extracted as a static PNG. For animated graphics, consider converting to GIF instead.
ICO format was developed by Microsoft for Windows application icons and website favicons. It can store multiple icon sizes in a single file, allowing Windows to display the appropriate size based on context (taskbar, desktop, etc.).
There is no server-imposed file size limit since the conversion happens entirely in your browser. The only limit is your device's available memory. Most ICO files are small (under 1MB) so this is rarely an issue.
Yes! ChangeThisFile also supports PNG to ICO conversion. However, converting PNG to ICO will create a single-size icon file, not a multi-resolution ICO like those created by specialized icon editors.
