Favicon preview in all sizes
Import an image and immediately see its real rendering in a browser tab, on a mobile home screen and as a shortcut icon, at all standard sizes (from 16x16 to 512x512). 100% local processing in your browser — nothing is sent to a server.
How it works
The same logo can look very different depending on display size: a fine detail visible at 512px often becomes unreadable at 16px. Instead of guessing, this tool resizes your image to each standard size directly via the browser's Canvas API and displays the result in realistic contexts (browser tab, home screen icon), so you can immediately spot the sizes where the logo loses legibility.
Which size should I check first before publishing my favicon?
First check the rendering at 16x16 and 32x32: these are the sizes most used in everyday browser tabs, and where fine details disappear most easily. If your logo remains recognizable at these sizes, it will almost always work well at larger sizes.
What's the difference from a simple favicon generator?
This tool focuses on the real visual preview at each size (with realistic context), to help you judge legibility before publishing, rather than on bulk exporting deployment-ready files. You can still download each size individually once you're happy with the rendering.
Resizing is done entirely via your browser's Canvas API; your image is never transmitted to a server.
