Convert JPG to ICO for your website

If you have a JPG version of your logo or brand image, you can convert it directly to an ICO favicon file without any intermediate steps. The tool renders your JPEG at all 10 required sizes using the Canvas API and packs them into a single standards-compliant .ico file.

💡 Pro Tip

JPEG doesn't support transparency. If your favicon needs a transparent background (so it adapts to dark/light browser themes), consider converting your JPG to PNG first using our JPG to PNG converter, then removing the background before generating the ICO.

Steps to convert JPG to ICO

  1. Open the Favicon Generator
  2. Upload your JPG image (drag in or click to browse)
  3. Click Generate ICO — all 10 sizes render instantly
  4. Preview each size in the result grid
  5. Download your favicon.ico file

Frequently Asked Questions

Yes. Upload any JPG image and the tool converts it to a multi-resolution ICO file. For best results, use a square JPG — non-square images are centre-cropped or letterboxed.
JPGs do not support transparency, so the ICO will have a white (or your image's) background. For transparent favicons, use a PNG with alpha transparency as input instead.
Use a JPG of at least 256×256 pixels. Larger source images (512×512 or 1024×1024) produce sharper results since the tool downscales to generate the various ICO sizes.
ICO is a container format holding multiple resolutions in one file, widely supported including by Internet Explorer. PNG favicons are a single resolution and require a separate file per size. Modern browsers support PNG favicons, but ICO provides the broadest compatibility.
Use the Image Crop tool to crop to a 1:1 aspect ratio before converting. Square input produces symmetric favicon output without unexpected cropping.
The ICO sizes below 64×64 are small enough that some detail loss is normal and expected. For the 256×256 size, quality is preserved. The important thing is that your logo/icon remains recognisable at 16×16 pixels.

Convert JPG to ICO – Create Favicons from Any Photo

ICO (Icon) is the native format for favicons and application icons on Windows. Despite modern browsers supporting PNG favicons, the ICO format remains essential for broad compatibility — particularly for IE/Edge legacy, Windows taskbar pinning, and `.ico` file associations on the Windows desktop. The ICO format is unique because it supports multiple image sizes embedded within a single file: a standard favicon.ico typically contains 16×16px, 32×32px, and 48×48px variants in a single file, letting Windows choose the appropriate size for each context.

This tool converts your JPG image to a proper multi-size ICO file directly in your browser. The conversion uses the HTML5 Canvas API to downscale your image to each required size, then packages them into the binary ICO format. Your image is never uploaded to a server.

  • For best results — Start from a square image (1:1 aspect ratio) at 512×512px or larger
  • ICO vs PNG favicon — Use ICO for the `favicon.ico` file in your root; use PNG for `favicon-32x32.png` and `favicon-16x16.png` `link` tags
  • Transparency — JPG has no transparency support; for transparent favicon backgrounds, use PNG as the input format
