How long does the conversion take?

Can I convert the file back from AVIF to EXR afterward?

What's the real difference between EXR and AVIF?
EXR (OpenEXR) is built around film and VFX compositing with extended dynamic range and multiple channels (a VFX-industry high-dynamic-range image format). AVIF is built around high-efficiency images for fast-loading modern websites instead (a modern AV1-based compressed image format) — different enough that this is a genuine format conversion, not just a rename.
Will I lose anything converting EXR to AVIF?
Converting to AVIF means adapting to a real constraint: unsupported by older browsers and some legacy software. Anything EXR (OpenEXR) carries — built as it is for film and VFX compositing with extended dynamic range and multiple channels — that has no equivalent there won't make the trip, but the core content converts faithfully.
Is AVIF objectively better than EXR?
Not objectively — AVIF is better specifically for high-efficiency images for fast-loading modern websites. For film and VFX compositing with extended dynamic range and multiple channels, EXR (OpenEXR) is still the right tool; that's exactly why both formats exist.
