Drag your files here
Or paste them with Ctrl+V. They never leave your device.
It is only meant for icons, not for large photos. As a JPG any phone, computer or website opens it, and photos stay small.
ICO is the container for Windows icons and website favicons, holding several sizes in one file.
Strengths: A single ICO carries the icon at 16, 32, 48 and 256 pixels so it looks sharp everywhere.
Limits: It is only meant for icons, not for large photos.
JPG (or JPEG) compresses photos lossily: it drops details the eye barely notices so the file is much smaller.
Strengths: Every phone, computer, social network and app can open it, and it is ideal for photographs.
Limits: It has no transparency and loses a little quality each time it is edited and saved again.
No. The ICO to JPG conversion runs entirely in your browser, with code downloaded from this site and executed on your device. You can check it in the Network tab of the developer tools or by going offline after the page loads.
JPG has no transparency: transparent areas of the ICO are filled with the colour you choose (white by default).
A little: JPG uses lossy compression. At the default quality the difference is not visible to the naked eye, and you can raise it in the options for maximum quality.
Your device’s memory sets the limit: on desktop, images up to about 100 megapixels; on mobile, up to 16.7. If an image is too large you are told before it starts.
Yes. Drop as many ICO files as you like: several are converted at the same time, depending on your processor cores, and when they finish you can download each JPG or all of them in a ZIP.
