Favicon Generator — Generate a Full Icon Set from One Image
Upload one image and instantly generate a complete set of favicon sizes from 16 to 512 px, with browser tab and bookmark previews. Generated locally, no upload, download as a zip.
A favicon is the small icon displayed in browser tabs, bookmarks, and favorites. Upload one image (a square source is recommended) and this tool generates the full standard size set (16 / 32 / 48 / 180 / 192 / 512 px) in one click, with tab and bookmark previews, ready to download as a zip. Everything is generated in your browser — your image is never uploaded.
Why Multiple Sizes Are Needed
16 / 32 px
Browser tabs, address bar, and bookmark bar icons.
180 / 192 px
iOS home screen and Android "add to home screen" icons.
512 px
PWA installation, app store listings, and high-resolution displays.
Tips for a Great Favicon
Use a Simple, Square Shape
Favicons are displayed very small. Complex artwork becomes an indistinct blob at 16 px. Use a square, high-contrast, minimal icon or lettermark for the best result.
Non-Square Images Also Work
Non-square images are automatically centered and cropped to a square. For the best output, provide a square source image.
