specialized bulk converter.">
Most free converters run a one-size-fits-all pipeline designed for the most common case. They do not account for Google's WebP compression study (developers.google.com/speed/webp), 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 bulk converter handles the exact scenario I described because I built it after encountering that very problem.
According to the WebP Container Specification (RIFF-based format), 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.
