UNDERSTAND YOUR FILES
AVIF vs. ICO: what changes?
A modern image format; this hub currently supports AVIF input only when the browser can decode it.
A Windows/web icon container. This hub generates one PNG-based 256×256 icon, not a multi-size icon bundle.
ICO files are used for website favicons and small Windows icons. This converter creates a square, 256-pixel icon with embedded PNG data. Choosing an output format changes how another app reads the file; it does not restore detail missing from your source.
Which settings should you choose?
The converter creates a single 256×256 PNG-encoded ICO. The original-dimensions choice controls initial processing, but the icon's final canvas is always 256×256.
Your files and privacy
Your selected file is converted on your device. You can download the new file while keeping the original unchanged.
Some formats work differently across browsers and devices. Check the converted result before using it for important work. Advertising and other optional website services may have separate privacy practices.
Format compatibility and limitations
AVIF source decoding depends on your browser, platform and AVIF variant. ICO output is one square icon containing PNG-compressed image data; it does not create a multi-resolution Windows icon set.
Actual output behavior depends on the input file, your browser, device resources and the converter engine. Check important files before sharing or replacing them.
