FORMATS
JPG vs ICO: what changes
You want your website favicon or a Windows icon from a logo or photo in JPG. JPG has no transparency: the icon keeps the image background. If your logo has a background, remove it first or start from a PNG. For the full set (Apple, Android and manifest), use Favicon generator.
| Feature | JPG | ICO |
|---|---|---|
| What it is | Compressed photo (JPEG). | Windows icon and favicon: several small images in one file. |
| Compression | Lossy: very light; every re-save loses a little detail. | Lossless (PNG inside the ICO). |
| Transparency, animation or sound | No transparency or animation. | Keeps transparency. |
| Compatibility | Universal: phones, websites, email and print. | Browsers (favicon) and Windows. |
| Best for | Photos to share, websites and email. | A website icon or a shortcut icon. |
JPG to ICO: common questions
Does converting JPG to ICO lose quality?
JPG has no transparency: the icon keeps the image background. If your logo has a background, remove it first or start from a PNG. For the full set (Apple, Android and manifest), use Favicon generator.
How many files can I convert at once?
Up to 10 images at once. You choose the sizes inside the ICO (16 to 256 px).
Does it work on a phone?
Yes, in current mobile browsers (Chrome, Safari, Edge, Firefox). Large files take a little longer on a phone, and the tab should stay open until the download is ready.
Are my files uploaded to a server?
No. The conversion happens inside your browser: the file is read and processed on your device and is not sent to Cocuyo or to any third party. You can check it in your browser’s network tools: your file is not sent.
Is it really free?
Yes. You can try it before signing up; to download the result we ask for a free account, with no subscription. Your free account comes with 30 welcome uses; after that, each use costs 1 credit (top-ups from US$1), and they are unlimited with Basic or Pro. It never adds a watermark.
