I optimize websites for a living — which means I deal with WebP files constantly. Modern CMS platforms serve WebP by default. But when I need to pull product images out of a site for a print catalog, or send assets to a client whose legacy software does not support WebP, I need a fast WebP to PNG converter. I tested four of them.
CloudConvert: handles WebP to PNG accurately. Upload-based. Fine for non-sensitive work. Free tier limits you to 25 conversions per day.
Convertio: similar to CloudConvert. Good conversion quality. Upload required. Queue times spike on weekends.
Online-Convert.com: supports batch conversion. Upload-based. Privacy policy has a "service improvement" clause I do not trust with client assets.
WebP2PNG: runs entirely in your browser. No upload, no signup, no daily limit. Batch 50 files. Keeps transparency intact. This is the one I use for client work — nothing leaves my machine. Convert WebP to PNG now →
