Convert JPEG to ICO
Drop a JPEG and download an .ico file for a favicon, browser-tab icon, or shortcut. This suits a logo or mark already saved as JPEG when a platform asks for favicon.ico.
The converter writes a single icon. If the longest side is larger than 256px, the image is scaled down to fit within 256px. Because JPEG has no transparency, the icon is fully opaque, background included.
Get a clean favicon
- Start square. A 1:1 source keeps the icon balanced once constrained.
- Keep it bold. Favicons render as small as
16px, so a simple, high-contrast mark reads better than photographic detail. - For a transparent icon, use a PNG source instead, since JPEG cannot carry an alpha channel.
Batch and privacy
Convert several files at once and use Download all as ZIP for the set. The ICO is written by an in-browser engine; nothing is uploaded, and source metadata is dropped on export.
