Why Choose 16x16?
Perfect dimensions for your specific needs with professional results
Favicon Ready
16x16 is the standard favicon size for tabs and bookmarks, keeping brand marks recognizable even when the browser UI shrinks to a tiny square at a glance.
Micro UI Precision
Designed for micro UI elements like status dots and toolbar glyphs, where a few pixels determine clarity and the icon must stay readable in dense layouts.
Pixel-Perfect Output
Sharp resizing preserves single-pixel strokes and contrast, avoiding soft edges that can make tiny icons look muddy on light or dark themes anywhere.
Ideal for Favicon Sets
Great as the base of a favicon set, pairing cleanly with 32x32 and 48x48 exports for high-DPI displays, pinned tabs, shortcuts, and favicon manifests.
Lightweight Files
Ultra-light files reduce requests and speed up page loads, especially when many small icons appear across menus, toolbars, lists, and navigation rails.
Sharp Brand Marks
Works well for simplified monograms and symbols, keeping your brand visible without complex detail at micro scale for badges and notifications in tight UI spaces.
Frequently Asked Questions
Everything you need to know about resizing images to 16x16
16x16 is used for favicons in browser tabs, bookmark bars, and older shortcut icons. It also fits tiny UI indicators where space is extremely limited and extra pixels would blur the layout or distract the interface across pages.
It can if the logo is simple. Use bold shapes, strong contrast, and remove fine detail. Cropping tighter around the main mark often improves clarity when the icon is scaled down to 16x16 and viewed at a glance by users.
Start from a clean high-resolution source, keep the main shape centered, and avoid thin lines. The preview helps you check readability before export so the icon does not disappear in the tab or toolbar across browsers.
PNG is great for crisp edges and transparency, ICO is still common for favicon bundles, and WebP can be used for internal UI sprites when you need the smallest file size without losing sharpness or color accuracy.
16x16 is still required, but many sites also provide 32x32 and 48x48 for high-DPI screens. Generate a set from one clean source and serve the best size for each device to avoid blurry icons in modern browsers and pinned tabs.
Yes. Crop to a square to keep proportions, or add padding if you must keep the full image. Stretching distorts tiny icons and makes edges look jagged, especially on high-contrast shapes and text. Padding keeps the mark balanced.
They are extremely small, often just a few kilobytes. Simple icons can be under 2 KB, which keeps favicon requests fast and avoids extra bandwidth when many pages load at once or in mobile conditions. This keeps UI bundles light.
The resize uses sharp sampling tuned for tiny outputs, but clarity also depends on your source. Simple shapes and high contrast yield the cleanest 16x16 result across browsers and themes while staying legible. Avoid thin details.
