ICO
ICO is the icon format of Microsoft Windows. A single ICO file can hold several images in different sizes, such as 16x16, 32x32, and 256x256 pixels. ICO files are used for application icons and website favicons.

PNG
PNG (Portable Network Graphics) is a raster image format with lossless compression. It keeps every pixel exactly and supports full transparency, which makes it ideal for screenshots, logos, graphics, and images with text. PNG photos are usually larger than JPG files of the same image.
What happens when ICO becomes PNG
Source format
ICO is the image source or target format for this conversion path.
Target format
PNG uses lossless compression and supports full transparency.
What changes
The ICO pixels are decoded and written using PNG compression and color capabilities.
- What is preserved
- Pixel dimensions and visible composition are preserved unless resize or crop settings are selected.
- What may be lost
- Layers, editable vectors, camera-raw controls, animation, high bit depth, and metadata are preserved only when PNG supports them.
- Codec and quality implications
- Color profile handling, bit depth, chroma sampling, and compression settings can change appearance or file size.
- Realistic limitations
- Multi-page, layered, animated, camera-raw, or very large images may be flattened, reduced to one frame, or rejected if the decoder cannot safely read them.
Conversion steps
- Upload a ICO file no larger than 1 GB.
- Confirm that PNG is selected as the target.
- Download the PNG file and check the result before deleting your source.
Troubleshooting
- The ICO file is rejected or will not open.
- Confirm that the file is not empty, password-protected, or corrupt and that its real format matches the extension.
- The PNG file is larger than expected.
- Choose a more efficient codec or lower quality setting when available. Lossless and uncompressed targets are often larger by design.
- Transparency, color, or animation changed.
- Choose a target that supports the needed feature and keep the original file; JPG cannot store transparency or animation.
Privacy and file retention
Uploads and converted files are processed automatically and irreversibly deleted within 24 hours. You can delete them sooner with the delete control. Convertr does not read, mine, sell, or manually review file contents.
