About JPEG
JPEG is the standard lossy image format, named after the Joint Photographic Experts Group that published it in 1992. It shrinks photos to a fraction of their raw size by discarding fine detail.
Photos from cameras and phones, images on the web and email attachments; every device and app opens it.
JPEG has no transparency, stores 8 bits per colour channel, and loses a little more quality every time it is saved again.
Convert JPEG to ICO online free, no account required — ICO is the icon format of Windows and website favicons.
Change JPEG to ICO without losing quality — convert JPEG to ICO free in your browser.
Why does my photo get worse every time I edit and save it as JPG? Each save re-compresses the image and piles new artifacts on the old ones — working from a lossless original and exporting once to JPG avoids the buildup.
About Icon (ICO)
ICO is the Windows icon format. One .ico file can hold several images of the same icon at different sizes.
Website favicons and the icons of Windows programs and shortcuts.
Each image in an ICO file can be at most 256 × 256 pixels, so the format is not suited to photos.
Why convert an image to ICO? A website favicon needs it — browsers ask for favicon.ico, and one ICO file carries every size from 16 to 256 pixels.
What changes when you convert JPEG to ICO
- The JPEG picture is re-encoded as ICO at the default quality settings, so it looks close to the original but is not bit-identical.
- JPEG is a lossy format and ICO is not: the ICO keeps the decoded JPEG exactly, but it cannot restore detail the JPEG compression already removed, and the file is usually larger.
Settings you can change
Before you convert JPEG to ICO, you can adjust: Width, Height, Scale fit, Crop position, Never enlarge, Quality, Lossless, Progressive, Remove metadata, Auto-orient from EXIF, Rotate, and Background.

Your converted ICO file is kept for 2 hours, then deleted.
