Frequently Asked Questions
Why convert BMP to ICO?
BMP (Bitmap Image File) uses uncompressed encoding and is best for legacy software compatibility, raw pixel data transfers, and simple image processing tasks. 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 BMP to ICO fail here?
Canvas cannot encode ICO, so the run ends in Conversion failed with no file written. Convert BMP to PNG, JPG, or WebP for a working download.
Which icon sizes ship from BMP?
Moot — no ICO is emitted from BMP input, so no size set builds. Convert BMP to PNG for icons and favicons instead.
What should I convert BMP to instead of ICO?
For BMP 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 BMP files upload when targeting ICO?
No — the attempt runs locally in your browser and fails before any save. Local-tool downloads stay unlimited.
