Tiny canvas, serious job
Preview your favicon before it goes live
A favicon appears beside your page title, in saved bookmarks, browser history and many search interfaces. This online favicon preview tool places one image into those everyday contexts so you can spot weak contrast, cramped edges and details that disappear at small sizes.
True small-size preview
Judge the icon at 16, 32, 48 and 64 pixels instead of trusting a large design canvas.
Light and dark checks
Switch the full preview surface to catch invisible edges and low-contrast artwork.
Private local testing
Your favicon stays inside your browser. No upload, account or watermark is involved.

Use real page details, adjust the artwork scale, and switch between light and dark.

Review and export
Inspect every context, download a normalized PNG size, and copy the favicon HTML.
A sharper site icon
What makes a good favicon?
Start with a square source
Use a 1:1 canvas so browsers do not stretch or unpredictably crop the artwork.
Design for 16 pixels
Favor a bold silhouette, limited colors and generous spacing. Fine text and thin strokes usually disappear.
Test contrasting backgrounds
Transparent icons should remain recognizable against both very light and very dark browser themes.
Provide several sizes
A 32 or 48 pixel favicon suits common browser contexts, while larger touch icons help on mobile devices.
Avoid relying on your logo wordmark
A full brand name may look excellent in a header but turns into a blur inside a browser tab. Use the most recognizable symbol or initial instead.
Common questions
Favicon preview tool FAQ
How can I preview a favicon online?
Upload your image to the studio above. It will appear immediately in a browser tab, bookmark list, search result, mobile shortcut and exact-size pixel test.
Which favicon file formats can I test?
You can preview PNG, SVG, ICO, JPG and WebP files, provided the browser can decode the file. A square PNG or SVG is usually easiest to inspect.
What size should a favicon be?
Use a square source of at least 48 × 48 pixels for a flexible starting point. Common delivered sizes include 16 × 16 and 32 × 32, with a separate 180 × 180 Apple touch icon.
Why does my favicon look blurry?
The source may be too small, overly detailed, or scaled between pixel boundaries. Start with a larger square image, simplify tiny details, and inspect the 16 px preview carefully.
Are my favicon files uploaded?
No. File reading, analysis and PNG export happen locally in your browser. Your image does not leave your device.
Is this online favicon tester free?
Yes. The favicon preview tool is free to use online, requires no signup and adds no watermark.
