Why teams trust this converter
Zero-Trust Ready
Files never leave the tab. JP2 binaries live inside WebAssembly memory and are disposed of immediately after producing a AVIF output.
Format-Aware Presets
We tune FFmpeg flags so JP2 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 JP2 → AVIF workflows.

Is it safe to convert JP2 to AVIF with FileConvert?
Yes. All conversions run locally in your browser using WebAssembly. Nothing is uploaded to external servers, so sensitive assets stay private.
How long does it take to change JP2 files into AVIF?
Processing happens on-device, so most JP2 to AVIF jobs finish in seconds. Larger videos scale with your CPU speed but never wait in a remote queue.
When should I pick AVIF instead of JP2?
JPEG 2000 offers wavelet-based successor to jpeg delivering high fidelity for archival and cinema workflows. whereas AV1 Image File Format is better suited for next-gen compression codec derived from av1 video, offering the best quality-to-size ratio.. Choose AVIF when you need next-gen web delivery.
