Generate professional website favicons with customizable dimensions directly from your SVG images in seconds.
SVG (Scalable Vector Graphics) is an XML-based vector image format standardized by the W3C in 2001. Instead of storing a fixed grid of pixels like JPG or PNG, an SVG file describes an image as mathematical shapes, paths, and curves written in plain text, which means it can be scaled to any size — from a favicon to a billboard — without losing sharpness. Because it's just text, an SVG can also be edited directly in code, styled with CSS, and animated with JavaScript, which is why it's the standard format for logos, icons, and illustrations across modern websites.
ICO is the native icon file format of Microsoft Windows, dating back to Windows 1.0 in 1985. What makes ICO distinctive is that a single file is actually a small container holding several versions of the same image at different resolutions and color depths — commonly 16×16, 32×32, 48×48, and 256×256 — so Windows, and browsers for favicons, can automatically pick the size that best fits the context. Because of this multi-size structure, converting a regular JPG, PNG, WEBP, or SVG image into ICO isn't a simple format swap: the source image needs to be resized and packed into that same multi-resolution container, which is exactly what a dedicated ICO converter automates.
Websites require precise favicon dimensions depending on where they are displayed—from browser tabs (16x16 or 32x32) to app shortcuts and high-density screens. Our tool runs 100% in your browser, ensuring total privacy while safeguarding image transparency and quality.
The standard **32x32 pixels** size works universally across almost all modern web browsers for standard tabs.
If your source image is rectangular (e.g., a wide logo), this option adds transparent padding around it to prevent distortion inside the square ICO file.
No, all conversion logic is executed locally within your browser using JavaScript for complete privacy.
