SVG TO
.ICO
FAVICON

Turn any SVG vector logo into a real multi-size .ico favicon. Because SVG scales without pixels, every size — 16 to 256 — looks crisp. No raster blurriness, no upscaling artifacts. Runs entirely in your browser.

Pixel-Perfect at Every Size
SVG is resolution-independent, so your favicon is rendered fresh at 16px, 32px, 48px... all the way to 256px — no interpolation blurriness, no upscaling artifacts.
Real Multi-Size .ico
Produces a proper binary .ico with ICONDIR headers and PNG-encoded images per entry — not a renamed PNG. Browsers and Windows pick the right size automatically.
Background Control
Keep SVG transparency for modern browsers, or bake in a solid background color for platforms that don't support alpha — like some Windows classic themes.
Aspect-Ratio Safe
Non-square logos are padded and centered in each square slot — never stretched. Your wordmark stays proportional at all sizes.
Preview Before Download
See your favicon rendered at each size on a checkered background before you download. Catch any sizing or spacing issues before they hit production.
100% Private
All rendering and encoding happens in your browser. Your SVG source never leaves your device — safe for unreleased logos, client work, or anything under NDA.

Process

HOW IT WORKS

Your browser renders the SVG fresh at each icon size — no upscaling, no resampled pixels — then packs everything into a single .ico.

01
Drop your SVG file
Your vector source is read as text. SVGs scale perfectly — no minimum resolution needed. PNG/JPG/WebP also accepted if that's all you have.
02
Pick sizes and background
The SVG is re-rendered from source at each chosen size (16/32/48/64/128/256) for pixel-perfect quality. Non-square logos are padded and centered, never stretched.
03
Download your .ico
All sizes get packed into a binary .ico with proper ICONDIR headers. Drop it in your site root — no configuration needed.
FAQ

COMMON QUESTIONS

PNG is a fixed-resolution raster image. When you scale a 512×512 PNG down to 16×16, the browser resamples it and you lose sharpness — especially for logos with thin lines or text.

SVG is a vector description: the browser redraws the shapes fresh at each target size. A 16px version is drawn as if it was designed at 16px. The result is crisper at every size — exactly what you want from a favicon.

16×16 — browser tab icon
32×32 — HiDPI (Retina) browser tabs
48×48 — Windows taskbar / pinned shortcuts
64×64 — some OS docks and file managers
128×128 — macOS dock (older apps)
256×256 — Windows app icons (.exe) and large-tile displays

The default 16 + 32 + 48 covers 99% of web favicon use cases. Add 256 only if you also want this file to serve as a Windows application icon.

A real .ico. The file starts with a proper ICONDIR header, followed by one ICONDIRENTRY per size, then PNG-encoded image data for each entry. Many cheap converters online just rename a PNG file — that happens to work in Chrome but breaks Internet Explorer and Windows Explorer. This tool produces the correct binary format that works everywhere.

Transparent is usually correct for SVG logos. Modern browsers and operating systems handle alpha in .ico files just fine, so your logo renders on whatever page or toolbar background is behind it.

Solid color is useful if your SVG has thin details that disappear on dark browser UIs (e.g., a white logo on a white site), or if you're targeting older Windows applications that don't render transparency.

Favicons must be square. A wide 4:1 wordmark at 16px would render 4 pixels tall — invisible. The tool uses fit-and-pad: it scales your logo to fill as much of the square slot as possible, then adds transparent padding around it to keep proportions. This is the correct approach. If you want a tighter crop, edit your SVG to have more balanced proportions first.

No. Your SVG is read as text in your browser, rendered on a <canvas>, and encoded to PNG — all locally. Only an anonymous "+1 conversion" count is sent to the server. The SVG source code, your logo, and the resulting .ico file never leave your device.
