Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. ICO binaries live inside WebAssembly memory and are disposed of immediately after producing a JP2 output.
Format-Aware Presets
We tune FFmpeg flags so ICO characteristics (color depth, metadata) persist when writing JP2 deliverables.
Ops-Level Observability
Each run exposes duration, file size deltas, and CPU hints so production teams can benchmark ICO → JP2 workflows.
