Why convert PNG to ICO?

ICO is required for favicons and some Windows application icon workflows.

PNG and ICO compared

PNG is a general raster image. ICO is an icon container; this converter stores one valid PNG-compressed icon frame.

Quality and transparency

Choose 16, 32, 48, 64, 128 or 256 pixels. The image is fitted to a square, so start with square artwork to avoid distortion.

Practical uses

  • Creating a favicon.ico
  • Preparing a Windows icon asset
  • Packaging transparent PNG artwork as ICO

Private browser-based conversion

Files stay on your device. The shared conversion pipeline validates file signatures, applies browser safety limits and checks the produced file signature. Browser codec support can still vary; the main converter guide explains current limits.

Questions

Frequently Asked Questions

Is the download a real ICO file?

Yes. It contains a valid ICO header, directory entry and PNG-compressed icon frame.

Does one ICO contain every size?

No. The current encoder creates one selected size per ICO file.

Can I convert multiple PNG files to ICO?

Yes. Convert up to 30 files in one batch, subject to the per-file and 300 MB total browser safety limits.

Are PNG files uploaded during conversion?

No. Decoding, pixel processing and encoding run locally in your browser.

Can I convert a different format on this PNG to ICO page?

This landing page accepts PNG input only. Use the main Image Converter for other supported source formats.

Does PNG to ICO preserve metadata?

Metadata is generally removed by the pixel conversion pipeline. The interface reports when requested metadata cannot be safely transferred.
