Why use ICO?
ICO files can contain several favicon sizes in one file and work well for browser tabs, desktop shortcuts and Windows apps.

Image to favicon workflow
Turn a source image into a dependable favicon.ico
The general converter accepts the most common raster and vector image formats, then packages your selected resolutions into one ICO file.
Choose the right source
Use PNG or SVG for logos and transparent artwork. JPG works for photographic sources, while WebP, BMP and GIF are useful when that is the original asset you already have.
Prepare a square composition
Place the main symbol in the center with enough breathing room. A square source prevents unexpected stretching across different embedded icon sizes.
Verify several resolutions
Inspect both the 16×16 preview and larger sizes. The smallest version should remain recognizable without relying on thin lines or tiny text.
Format-specific help
Image to ICO questions
Which source format is best for a favicon?
PNG and SVG are usually best for logos because they support clean edges, and PNG can preserve transparency. JPG is suitable when the favicon is based on a photograph.
Can one ICO contain several dimensions?
Yes. The generated ICO can include multiple embedded sizes so browsers and desktop software can choose the closest resolution.
Is the image sent to a server?
No. Conversion is performed locally in the browser and the source file is not uploaded.
