Frequently Asked Questions
Why convert GIF to ICO?
GIF (Graphics Interchange Format) uses lossy (limited to 256 colors) encoding and is best for simple animations, memes, and images on platforms that support animated GIFs natively. 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 GIF to ICO fail here?
Canvas cannot encode ICO, so the run ends in Conversion failed with no file written. Convert GIF to PNG, JPG, or WebP for a working download.
Which icon sizes ship from GIF?
Moot — no ICO is emitted from GIF input, so no size set builds. Convert GIF to PNG for icons and favicons instead.
What should I convert GIF to instead of ICO?
For GIF 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 GIF files upload when targeting ICO?
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.
