Frequently Asked Questions
Why convert JPEG to ICO?
JPEG (Joint Photographic Experts Group) uses lossy compressed encoding and is best for photographs, web images, and social media where smaller file size matters more than perfect quality. 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 JPG to ICO fail here?
Canvas cannot encode ICO, so the run ends in Conversion failed with no file written. Convert JPG to PNG, JPG, or WebP for a working download.
Which icon sizes ship from JPG?
Moot — no ICO is emitted from JPG input, so no size set builds. Convert JPG to PNG for icons and favicons instead.
What should I convert JPG to instead of ICO?
For JPG 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 JPG files upload when targeting ICO?
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.
