Common use cases

  • Create a favicon for a new website.
  • Produce multiple icon sizes from one logo.
  • Replace an outdated browser-tab icon.

Tips for better results

  • Start with a simple square logo for best small-size clarity.
  • Avoid tiny text that disappears at 16×16 pixels.
  • Test the icon on both light and dark browser themes.

Privacy, compatibility and output quality

The supported processing for this tool runs locally in the browser. That means your selected image file stays on the device during the operation instead of being sent to Kaazo for server-side conversion. Browser-based processing can still be limited by your device's memory, browser capabilities and the complexity of the source file, especially with very large documents.

For important business, legal, financial or archival documents, keep the original and inspect the downloaded result carefully. Complex fonts, forms, layers, spreadsheet features, OCR text or unusual file structures may not reproduce exactly the same way as specialist desktop software.
