TIFF to HEIC output is not produced here — TIFF input may not decode in browsers, and Canvas has no HEIC encoder, so conversion fails locally. Convert TIFF to PNG/JPG/WebP instead — local, unlimited saves.

Frequently Asked Questions
Why convert JPEG XL to HEIC?
JPEG XL (JPEG XL) uses lossy or lossless encoding and is best for next-gen image archival — better compression than JPEG with support for wide gamut and HDR. HEIC (High Efficiency Image Container) uses lossy or lossless encoding and excels at Apple device photos — iPhone and Mac default format with excellent compression efficiency. 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 JXL to HEIC fail here?
Two barriers at once: JXL input may not decode in browsers, and Canvas has no HEIC encoder. The run ends in Conversion failed before any save.
Does Apple Photos accept the JXL result?
Moot — no HEIC is emitted from JXL input. Convert JXL to JPG for Apple Photos instead.
What should I convert JXL to instead of HEIC?
For JXL 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 JXL files upload when targeting HEIC?
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.

Convert image batches to JPG, PNG, WebP, AVIF, GIF, BMP, ICO, or SVG outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80; applies to lossy encodes).

Image Format Converter
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.
