How I Fixed a Broken Multi-Size Favicon Generator

2026-07-10 · 3 min read

I was auditing a Shopify store's Core Web Vitals and found 404 errors on /apple-touch-icon.png and /favicon-32x32.png — two icons that did not exist but browsers kept requesting. Every missing request added 200ms of blocking time.

The Solution Is Simpler Than You Think

Most people overthink this problem. The actual fix is straightforward once you understand what Apple's Safari Web Content Guide (apple-touch-icon specification) actually requires. Here is what matters:

Format integrity: The output must conform to W3C Web App Manifest specification (w3.org/TR/appmanifest), not just look correct.
Metadata preservation: Color profiles, alpha channels, and resolution data must survive the conversion intact.
Batch reliability: Processing 100 files should produce the same quality as processing 1 file.

I built our SVG favicon maker to handle all three requirements in a single step. No configuration, no quality trade-offs.

What Changed After I Switched

My client revision requests dropped by about 80%. The files are right the first time because the converter does not take shortcuts. Try it on your next batch →
