How to Convert JPG to ICO
- 1
Drag one or more JPG images into the box above, or click it to browse and select them from your computer — batches of files all convert together.
- 2
Pick which favicon sizes you want included — 16×16, 32×32, and 48×48 are all checked by default, and you can uncheck any size you don't need before or after dropping files.
- 3
Your browser resizes the image to each checked size on a canvas, packs every size into a single multi-resolution ICO file, and hands it back to you — download each favicon.ico individually or use Download All for the whole batch.
Why Convert JPG to ICO
ICO is the format browsers and operating systems expect for favicons — the small icon shown in a browser tab, bookmark list, or home-screen shortcut. Unlike an ordinary image file, a single ICO can bundle several versions of the same picture at different sizes, which lets browsers and devices pick whichever size renders most crisply for the spot they're displaying it in, whether that's a tiny 16×16 tab icon or a larger 48×48 shortcut icon.
Most logos and photos start out as a JPG, which browsers don't recognize as a favicon at all — dropping a .jpg into a website's favicon link tag simply won't work in most browsers. Converting to ICO with the right square sizes baked in solves that in one step, producing a single favicon.ico file you can upload straight into a site's root directory or reference from a tag in the page's head.
Because the resizing and packing both happen on a canvas inside your browser tab, your image is never uploaded anywhere to generate the favicon — it's read, resized at each selected dimension, assembled into the ICO container, and handed back to your downloads folder without a single byte leaving your device. That makes it a quick, private way to turn a logo or photo into a favicon without installing design software or trusting a random upload tool with your image.
JPG vs ICO: Format Comparison
| Feature | JPG | ICO |
|---|---|---|
| Purpose | General photo storage | Favicons & app icons |
| Multi-Resolution | One size per file | Bundles several sizes in one file |
| Transparency | No | Yes |
| Browser Recognition | Not usable as a favicon | Standard favicon format |
| File Size | Larger, single image | Small — tiny icon dimensions |
| Editing Software | Universal | Limited to icon-aware tools |
| Best For | Photos, general images | Browser tabs, shortcuts, app icons |
| Free to Use | Yes | Yes |
JPG is a general-purpose photo format that browsers don't recognize as a favicon. ICO packages one or more resized versions of an image specifically for browser tabs, bookmarks, and shortcuts.

Frequently Asked Questions
What is an ICO file?
ICO is the icon file format used by Windows and web browsers for favicons, application icons, and shortcuts. Unlike a normal image, a single ICO file can store several versions of the same picture at different sizes all bundled together.
What sizes does a favicon ICO need?
16×16 and 32×32 cover the vast majority of cases — browser tabs typically use 16×16, while 32×32 is used for sharper displays and desktop shortcuts. 48×48 is useful for larger shortcut icons. All three are checked by default, and you can uncheck any you don't need.
Can I use a PNG instead of JPG as input?
Yes. The dropzone also accepts PNG images — both formats are decoded the same way using your browser's built-in image support before being resized and packed into the ICO file.
Will my logo look good at 16×16?
Simple logos with bold shapes and limited fine detail tend to hold up well at 16×16, while busy or highly detailed images can look cluttered at that size. If a logo looks muddy at the smallest size, try simplifying it before converting, or rely on the 32×32 and 48×48 sizes instead.
Is my image uploaded to a server?
No. Every step — decoding the JPG, resizing it on a canvas, and assembling the ICO container — happens entirely inside your browser tab. Nothing is uploaded, stored, or logged on a server at any point.
