How does it work?

Each size is rendered to an in-memory canvas with a centered cover crop, then encoded as PNG. The ICO output stores the 16, 32, and 48 px PNG frames in a valid ICO directory.

Each source has its own vertical section with a preview, file details, and generated outputs. The batch overview previews generated icons; Download all packages every PNG and ICO in one ZIP, while More actions passes each 192 px PNG to another image tool.

Source images are never overwritten. Generated Blob URLs are released when an image is removed or the page is closed.

What are the edge cases and limits?

  • Each source image is limited to 25 MB and 40 MP. A batch can contain up to 20 images and 100 MB total. Transparent pixels remain transparent in PNG outputs.
  • The tool does not generate SVG masks, platform-specific safe-area padding, or an application manifest file.
  • Always preview icons at their target size; fine detail and small text may disappear at 16 px.
