Convert JPG to ICO Online
Convert JPEG images to ICO icon format online — browser-based, no software needed.
ICO is the icon format used by Windows applications, website favicons, and shortcut files. Converting a JPG to ICO is the quickest way to create a basic icon from a photograph or logo. Dockitt resizes your image to 256×256 pixels (the standard maximum ICO size) and produces an ICO-compatible file directly in your browser. No upload, no software installation required.
How to use
- Click 'Choose JPG' and select the JPEG image you want to use as an icon.
- Click 'Convert to ICO' and wait while the image is resized and processed.
- Download the ICO file and use it as a favicon, app icon, or Windows shortcut icon.
FAQ
What size will the ICO file be?
The output icon is resized to 256×256 pixels, which is the standard maximum size for ICO files. The source image is scaled to fit within that canvas while preserving its aspect ratio. For use as a favicon (16×16 or 32×32 px), the browser or operating system will scale the 256×256 icon down automatically.
Can I use this ICO as a website favicon?
Yes. Upload the downloaded ICO file to your web server and reference it in your HTML with a link tag: <link rel='icon' href='/favicon.ico'>. Most web servers and browsers handle ICO files for favicons. For modern websites, you may also want to add a PNG favicon at 32×32 or 192×192 for broader device support.
Will my image be cropped to fit 256×256?
No. The image is scaled to fit within 256×256 pixels while maintaining its original aspect ratio. If the image is not square, it will be centred on the canvas with transparent margins (since ICO supports transparency). The image is never cropped.
My JPG has a background — will it look good as an icon?
Icons typically look best with a transparent or simple background. A JPG with a complex photographic background can be used as an icon, but it may look cluttered at small display sizes. For best results, use an image with a simple background or consider removing the background first using an image editor.
Is this ICO format compatible with all Windows versions?
The 256×256 ICO format is supported by Windows Vista and later. Older versions of Windows (XP and earlier) used smaller icon sizes (32×32 and 48×48 px). For maximum compatibility with legacy Windows systems, you would need a dedicated ICO editor that can embed multiple sizes in a single ICO file.
Is the conversion done in my browser or on a server?
The conversion runs entirely in your browser using the Canvas API. Your image is never uploaded to any server.
