About converting JPG to ICO

The same idea as PNG to ICO, starting from a JPG instead: this tool packs a photo or graphic into the multi-resolution .ico container Windows and website favicons expect.

The JPG is resized to the standard icon resolutions and packed into a single .ico file, entirely in your browser. A JPG source has no transparency to preserve, so the icon will have a solid background rather than a transparent one — for a transparent icon, start from a PNG instead.

Supported files

Accepts JPG images. Produces a .ico file with multiple embedded icon sizes.

Is my file uploaded?

No. Packing the icon sizes happens entirely in your browser — the image is never uploaded.

How to JPG to ICO

    Drop in a square JPG for the sharpest icon; it's processed on your device.

  2. 2

    Convert

    It's packed into a single .ico file holding 16, 32 and 48 px versions.

  3. 3

    Download

    Save the .ico for a favicon or a Windows app icon.

JPG to ICO — frequently asked questions

What sizes are in the .ico?+

16, 32 and 48 px, packed into one file.

JPG or PNG for an icon?+

PNG is better — it keeps transparency and sharp edges. Convert from JPG only when that's the file you have.

Is the image uploaded?+

No — everything happens in your browser.

Is there a free way to turn a JPG into a website icon?+

Yes — this tool packs the icon sizes entirely in your browser from a JPG, free and with nothing uploaded.

Do you upload my files to a server?+

No — every tool here processes your files entirely on your device, and nothing is uploaded to a server. The only exception is the AI tools, which send the extracted text (not the file) to Claude to do their work.

Is there a file size limit?+

There's no artificial limit we impose, but since processing happens in your browser, very large files (500+ MB or 1,000+ pages) are limited by your device's memory rather than by us.
