How I Fixed a Broken SVG to PNG Conversion

2026-07-12 · 3 min read

A print shop rejected my client's banner artwork because the PNG was '72 DPI web resolution.' The source was a vector SVG. I re-exported at 300 DPI through svg2png.org and they accepted it immediately.

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 W3C SVG 1.1 specification (w3.org/TR/SVG11), 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 logo exporter handles the exact scenario I described because I built it after encountering that very problem.

The Specification Says It Should Work

According to MDN Web Docs on CanvasRenderingContext2D.drawImage(), 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.
