How to use JPG to ICO Converter

  1. 01

    Upload your JPG

    For the cleanest favicon, use a square photo or logo cropped tightly to the subject — up to 20 MB anonymous, 50 MB free account, or 200 MB paid.

  2. 02

    Automatic square canvas fit

    Your JPG is fit onto a square canvas before the icon sizes are built. JPG has no transparency, so the background of your photo stays visible in the icon.

  3. 03

    Multi-size .ico generation

    16×16, 32×32 and 48×48 versions are rendered and packed into a single .ico — the fixed set browsers and Windows expect for favicons.

  4. 04

    Download your favicon-ready ICO

    Grab the .ico via a signed download link — ready to drop into your site. It is auto-deleted within 24 hours, and the uploaded JPG within 6–24 hours.

Why choose our JPG to ICO Converter

Favicon-ready across browsers and OS

The 16×16, 32×32 and 48×48 sizes packed into one .ico match exactly what Chrome, Firefox, Safari, Edge and Windows shortcuts request.

Sharp at every requested size

Each size is rendered separately from your canvas-fit source instead of crudely scaling one bitmap, so small sizes stay legible.

Your photo stays private

Uploads use HTTPS, converted .ico files are auto-deleted within 24 hours, and uploaded JPGs are removed within 6–24 hours.

Free to build your favicon

Anonymous visitors get 1 free server conversion up to 20 MB; a free account adds 3 conversions every 30 days at 50 MB with batches of 5.

No signup to make your first favicon

Build and download your first .ico instantly — create an account only when you need more conversions or batches.

Settings guide

Multi-size output (16/32/48, fixed)
No options to set. The JPG is fit onto a square transparent canvas, then 16×16, 32×32 and 48×48 versions are generated and packed into one .ico file. Note that JPG itself has no transparency, so the visible image keeps its original background.

About the formats

JPG

JPG (also written JPEG) is the most widely used lossy image format for photographs, standardized by the Joint Photographic Experts Group in 1992. Practically every camera, phone, and image application can create and open it.

Its strengths are small file sizes for photos and universal compatibility across devices, browsers, and software. The trade-offs: lossy compression introduces artifacts, there is no transparency support, and quality degrades a little more with every re-save. Use JPG for photographs; choose PNG for screenshots, logos, or anything that needs sharp edges or transparency.

ICO

ICO is the Windows icon format, best known today as the container behind website favicons. A single .ico file can hold the same image at several sizes — commonly 16, 32, and 48 pixels — so the system can pick the right one.

For favicons, ICO still has the broadest compatibility: browsers request /favicon.ico by default, and even very old clients understand it. The format tops out at 256 x 256 pixels and is not meant for photos or general images. Modern sites often add PNG or SVG icons alongside, but shipping a classic ICO remains the safe baseline.

Troubleshooting

My favicon looks blurry
Use a square source image of at least 48×48 pixels, ideally larger. Busy photos rarely read well at favicon sizes — crop tightly to the key subject or logo before converting.
The icon shows a white or rectangular background
JPG cannot store transparency, so whatever background the photo has stays in the icon. For a favicon with a transparent background, start from a PNG with alpha and use our PNG to ICO tool instead.
My file won't upload
Make sure the file is a real JPG with a .jpg or .jpeg extension — files renamed from other formats are rejected. Also check the size limits: 20 MB anonymous, 50 MB free account, 200 MB paid.

FAQ

What does the generated ICO contain?
A multi-size .ico with 16×16, 32×32 and 48×48 versions of your JPG. The source is fit onto a square transparent canvas before the sizes are generated; the sizes themselves are fixed.
Is JPG a good source for a favicon?
It works, but JPG has no transparency, so the icon keeps its rectangular background. For best results use a square image — or prefer a PNG with transparency and our PNG to ICO tool.
How private is the conversion?
Files are uploaded over HTTPS, converted outputs are auto-deleted within 24 hours, and uploaded inputs are removed within 6–24 hours.
What limits apply?
Anonymous: 20 MB and 1 free server conversion. Free account: 50 MB, 3 conversions per 30 days, batches of 5. Paid: 200 MB and batches of 100.
Can I choose different icon sizes than 16/32/48?
Not currently — the .ico always contains this fixed set of three sizes, matching what Windows and browsers request for favicons and shortcuts.
Can I convert multiple JPGs into ICO files at once?
Yes. Free accounts can batch up to 5 files at a time; paid accounts up to 100.
Will the favicon work in every browser and operating system?
Yes. The multi-size .ico this tool builds follows the standard favicon format recognized by Chrome, Firefox, Safari, Edge and Windows shortcuts.
