    Drag one or more JPG files onto the dashed area, or tap it to pick them from your device.

Good to know. An ICO file holds the same icon in several sizes (16 to 256 pixels): Windows and browsers pick the right one.

JPG

JPEG (Joint Photographic Experts Group)

The photo format par excellence. It compresses the image by discarding details the eye barely notices, so a 12-megapixel photo weighs only a few megabytes. Any device can open it, from an old phone to a photo lab’s printer.

Questions about JPG and ICO

Are my JPG files uploaded to a server?

No. The conversion from JPG to ICO happens entirely in your browser, using your device’s computing power. Files aren’t sent or stored anywhere: when you close the page they’re gone from memory too.

How many files can I convert at once?

Up to 100 files at a time. There’s no fixed size limit: it depends on your device’s memory. On smartphones it’s best to work in smaller batches with heavy files such as videos.

Does it work on iPhone and Android?

Yes, with up-to-date Safari, Chrome, Firefox, Edge and Samsung Internet. On phones, converted files end up in the Downloads folder or the Files app.

Do I need an internet connection?

Only to open the page (and, the first time, to download the components needed for that type of file). After that the conversion keeps working even if the connection drops.
