Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. WebP binaries live inside WebAssembly memory and are disposed of immediately after producing a AVIF output.
Format-Aware Presets
We tune FFmpeg flags so WEBP characteristics (color depth, metadata) persist when writing AVIF deliverables.
Ops-Level Observability
Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark WebP → AVIF workflows.
