How to convert JPG to ICO

The JPG is decoded on your device and re-encoded as ICO with the browser's own graphics engine. Because nothing is uploaded, even dozens of photos convert quickly and privately. ICO is the icon format used for favicons and Windows application icons.

Step 1: Choose your JPG file
Drag and drop a .jpg, .jpeg, .jfif file onto the converter or click to browse. It works on desktop, tablet and phone.
Step 2: Convert to ICO
Each image is converted to ICO immediately.
Step 3: Download the ICO
Save each result individually, or download everything as a single ZIP when you convert several files.

Good to know

Converting to ICO is lossless from here on, but it cannot restore detail already lost in the JPG compression, and files are usually larger.
The icon contains 16, 32, 48, 64, 128 and 256 px sizes, which is what Windows and browsers expect for favicons and app icons.
Photo metadata (EXIF, GPS location) is removed from the converted image, which is good for privacy.

Why use this JPG to ICO converter?

Batch conversion: drop several images at once and download a ZIP.
Nothing is uploaded, so personal photos stay private.
Original resolution is kept.
No watermark, no account, no app to install.

Is it free?

Yes. Converting JPG to ICO is free, with no watermark, signup or email required. Local conversions have no artificial file-size or daily cap; the practical limit is your device.

Is my file uploaded?

The JPG file is processed entirely in your browser. It is never uploaded, never stored and never seen by anyone, so this is safe for confidential files.

About the formats

What is JPG?

JPG, or JPEG, is an image format named after the Joint Photographic Experts Group, which created the standard in the early 1990s. It uses lossy compression that discards detail the eye barely notices, so photos take up far less space. It does not support transparency or animation, and every time you re-save a JPG it can lose a little more quality.

Use JPG for photographs and images with smooth colour gradients that you want to share, upload or email at a small size. Avoid it for logos, screenshots with text or anything that needs a transparent background; PNG handles those better.

What is ICO?

ICO is the icon file format used by Microsoft Windows for programs, shortcuts and folders. A single ICO file can contain the same image at several sizes and colour depths, such as 16×16, 32×32 and 256×256 pixels, so the system picks the best one for each context. It supports transparency, and modern ICO files can embed PNG images inside.

Use ICO for Windows application icons and for favicon.ico, the small icon browsers show in tabs and bookmarks. Include several sizes so the icon stays sharp everywhere. For other purposes, a PNG or SVG is easier to work with.
