常見問題

Why might decoding fail?
Some JXL files use features (lossless mode, animation, HDR) that older ffmpeg.wasm builds don't fully decode. Re-encoding from source helps.
Why isn't there native JXL support in my browser?
Chromium removed default JXL support; Safari 17+ added it. This tool decodes via ffmpeg.wasm so it works regardless.
