JPG to ICO
Convert a JPG photo into a multi-size Windows .ico icon file, with a center-cropped square preview at every size, built in your browser.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Sample image — choose your own JPG to replace it.
How the JPG to ICO converter works
- Choose a JPG image and select which icon sizes you want included.
- The tool center-crops the image to a square, then resizes it to each chosen size on an HTML canvas.
- Each resized version is encoded as PNG and packaged into a single valid .ico file, ready to download.
FAQ
Why is my JPG cropped to a square in the icon?
Windows .ico files store square images. A non-square JPG is center-cropped to a square before being resized, rather than stretched — stretching would distort the image noticeably at small icon sizes.
Does JPG support transparency in the resulting icon?
No — JPG has no alpha channel, so the square crop will show the JPG's actual edge pixels with no transparency. If you need a transparent icon, start from a PNG instead using our PNG to ICO tool.
Which sizes should I include?
The defaults (16, 32, 48, and 256 pixels) cover the most common Windows use cases — taskbar, desktop, and large-icon views. Add 64 and 128 as well if you want extra intermediate sizes for high-DPI displays.
Is my image uploaded anywhere?
No. Every resize and the final .ico file are built entirely in your browser using an HTML canvas — the image is never sent to Online Tool Store or any other server.
