Frequently Asked Questions
Why convert HEIC to ICO?
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. ICO (Windows Icon) uses lossless (multiple sizes) encoding and excels at favicons and app icons — standard format for website bookmarks and Windows application icons. 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 ICO fail here?
HEIC input decodes via heic2any, but Canvas cannot encode ICO, so the run ends in Conversion failed. Convert HEIC to PNG instead.
Which icon sizes ship from HEIC?
Moot — no ICO is emitted from HEIC input, so no size set builds. Convert HEIC to PNG for icons and favicons instead.
What should I convert HEIC to instead of ICO?
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 ICO?
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.
