Frequently Asked Questions
Can I use a JPG image as a website favicon?
Yes — but browsers expect an ICO or PNG file, not a raw JPEG. Converting your JPG to ICO gives you the multi-size container format that web servers and Windows both recognize, so your favicon displays correctly in every browser tab and bookmark list.
What sizes are packed into the ICO file when I convert a JPG?
A standard ICO file contains multiple embedded sizes — typically 16×16 for browser tabs, 32×32 for taskbars and bookmark menus, and 48×48 for desktop shortcuts — all derived from your original JPEG in a single conversion.
Will converting a JPG to ICO reduce image quality?
The source JPEG is already a lossy format, so some compression artifacts may be visible at small icon sizes. Starting from the sharpest, highest-resolution JPG you have will give the cleanest result inside the ICO.
How do I add a favicon to my website after converting a JPG to ICO?
Download the ICO file, place it in your site's root directory, and add a link tag to your HTML head: `<link rel="icon" href="/favicon.ico">`. Browsers will pick it up automatically on the next load.
Is there a file size limit for JPG to ICO conversion?
Image Machine runs entirely in your browser, so there is no server-side upload restriction. Very large JPEG files may take a moment to process depending on your device, but they are never sent to any external server.
