How to convert JPG to ICO
Drop files into the box, click to browse, or paste from your clipboard. Batch is supported.
Choose a favicon set, a single size, or a multi-size ICO. Adjust quality and transparency.
Grab the .ico, the full favicon package (.zip), or copy the ready-made HTML code.
JPG vs ICO: format comparison
| JPG | ICO | |
|---|---|---|
| Primary use | Photos & camera images (lossy compression) | Windows icons & favicons |
| Transparency | ❌ No alpha channel | ✅ Yes (32-bit BMP or PNG) |
| Animation | ❌ No animation | ❌ Static only |
| Multiple sizes | ❌ One size per file | ✅ One file can hold 16–256px |
| Where it runs | All modern browsers & cameras | Windows, browsers (favicon), apps |
| Why convert | — | JPG can't be used as a favicon.ico or Windows icon directly |
Convert JPG to ICO at 256×256 or any other size
The ICO format can store icons from 16×16 (small browser tab) to 256×256 (Windows 10/11 high-DPI). Instead of hunting for a JPG that happens to be the right size, use the size presets here: the converter scales your image to 16, 32, 48, 64, 128, 180, 192 or 256 pixels — or type any custom size. A 256×256 JPG to ICO conversion is the most common request because that is the largest size Windows and macOS recognize natively, and it is automatically downscaled into every smaller size inside the same .ico file.
Lossless and high-quality JPG to ICO output
Many free converters visibly degrade icons, which matters at 16×16 where every pixel counts. This tool offers three scaling levels: Lossless stores the icon as PNG data inside the ICO (no quality loss at all), High uses high-quality resampling for sharp edges, and Balanced is the fastest. Because JPG has no alpha channel, the background fill matters: choose White fill for light sites or a solid background, and check the preview grid — you can judge legibility at every size before downloading. For icons that need transparent corners, start from a PNG with transparency instead.
Why is my icon blurry at 16×16?
Small sizes lose detail because the source image is downscaled. Best practice: start from a large, simple shape (a 256×256 icon with high contrast and bold shapes survives 16×16 best). The preview grid in the result panel lets you check this before you commit to the download.
Frequently asked questions
Is it free to convert JPG to ICO?
Yes — completely free, with no limits, no registration and no watermark. This page has no paywall and no file-count restrictions for normal use.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser using JavaScript. Your files never leave your device — you can even unplug your internet after opening the page and the tool still works.
Can I use the output as a website favicon?
Yes — that is the main use case. Choose the "Favicon set" mode to get favicon.ico, PNG icons at 16/32/180/192px, apple-touch-icon, site.webmanifest and the HTML code to paste into your site's head. Browsers request multiple sizes, so the full set gives the sharpest result everywhere.
What sizes should a favicon be?
Minimum you need: favicon.ico (16+32+48 inside one file), favicon-32x32.png and favicon-16x16.png. For best results on all platforms add apple-touch-icon.png (180×180), android-chrome-192x192.png and android-chrome-512x512.png. The favicon-set mode generates all of these automatically.
Can I convert JPEG and JFIF files too?
Yes. JPEG, JPG and JFIF are the same format family, and all of them are accepted here — just drop the file in. The output is always a proper .ico with PNG-encoded frames, no matter which file extension your source used.
Does converting reduce image quality?
Your source JPG is already lossy, but the conversion itself adds no further loss: with the "Lossless" option the icon is stored as PNG data inside the ICO. With "High" or "Balanced", resampling may soften edges when scaling down. For the sharpest 16×16 result, start from a large, high-contrast source image.
My JPG has a background I don't want — what can I do?
JPG can't store transparency, so the background is baked into the image. Crop the image first (or pick a PNG source) if you need transparent corners. Otherwise, use "White fill" or keep the original background — both give predictable results on any site.
