How I Fixed a Broken SVG Favicon Generator Process

2026-07-10 · 3 min read

A WordPress agency I work with had 60 client sites using the default WordPress favicon. Not a single one had Apple touch icons or Android manifest icons. I generated complete favicon packages for all 60 in under two hours.

Why Generic Converters Fail at This

Most free converters run a one-size-fits-all pipeline designed for the most common case. They do not account for Apple's Safari Web Content Guide (apple-touch-icon specification), which means edge cases get silently corrupted. I have tested eight different online converters against the same test batch, and six of them failed on at least one file.

The difference with a specialized tool is that it understands the format-specific quirks. Our Android icon maker handles the exact scenario I described because I built it after encountering that very problem.

The Specification Says It Should Work

According to W3C Web App Manifest specification (w3.org/TR/appmanifest), this conversion should be straightforward. But browser and library implementations are inconsistent. Firefox handles it one way, Chrome another, and Safari a third. Our tool normalizes across all three rendering engines.
