Free JPG to ICO converter

Why convert JPG to ICO?

People convert JPG to ICO because JPG discards a little more detail every time it is saved, and it cannot store a transparent background, while ICO is what Windows icons and browser favicons actually require.

How to convert JPG to ICO

1. Choose your JPG file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .ico. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .jpg file?

JPG (also written JPEG) is the universal photograph format — small files that open on every device made in the last twenty-five years. It is lossy, discarding detail the eye is least likely to miss, which makes it excellent for photos and poor for screenshots, logos and text, where it leaves visible smudging.

What is a .ico file?

ICO is the Windows icon container, used for favicons and application icons. One file can hold the same image at several sizes so the system can pick the right one; 16, 32, 48 and 256 pixels are the usual set.

What to expect from this conversion

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality. Windows icons are capped at 256×256, so a larger picture is scaled down to fit.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your JPG file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
