Generate favicons from one image
Add one image (a square logo works best), optionally flatten transparency onto a background color, and download the complete favicon set with the HTML snippet.

How to use it
- Add one image; a square logo gives the cleanest results.
- Optionally pick a background color for JPG-style flattening, or keep transparency.
- Download the ZIP with all sizes, the .ico file and the HTML snippet.
Limits & formats
One image per run, up to 20 MB and 25 megapixels; non-square images are center-cropped to squares. Sizes larger than your source are included but upscaled (soft edges) — the tool marks them. The .ico embeds 16/32/48 px PNG frames, which all current browsers accept. No animated or SVG favicons in this first version.
Privacy
Your image is processed locally in this browser tab. YYSI servers never receive your files. Only anonymous usage counters (tool name, success or failure, rough size range) are recorded.
