Frequently Asked Questions
Why convert HEIC to JPEG XL?
HEIC (High Efficiency Image Container) uses lossy or lossless encoding and is best for Apple device photos — iPhone and Mac default format with excellent compression efficiency. JPEG XL (JPEG XL) uses lossy or lossless encoding and excels at next-gen image archival — better compression than JPEG with support for wide gamut and HDR. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Why does HEIC to JXL fail here?
HEIC input decodes via heic2any, but Canvas cannot encode JXL, so the run ends in Conversion failed. Convert HEIC to PNG instead.
Which browsers open the HEIC JXL?
Moot — no JXL is emitted from HEIC input. Convert HEIC to WebP for modern browsers instead.
What should I convert HEIC to instead of JXL?
For HEIC sources: PNG for exact pixels, JPG for photos at fixed 0.92, or WebP at 0.85 — every one encodes locally with unlimited saves.
Do HEIC files upload when targeting JXL?
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.

Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
