Batch-convert ICO icons into high-quality SVG paths.
Trace legacy favicons and Windows icons into real SVG paths. Control colors and detail, inspect each result, and export individual files or a complete ZIP.
Image contents are processed temporarily and discarded after conversion.
Add ICO images and control the result.
Drop or choose up to 10 images.

How it works
How do you convert an image to SVG?
01Upload ICO icons
Grab the favicon.ico from an old site or the icon files from a legacy Windows app and drop them into the converter.
Modernize an aging favicon.ico into an SVG favicon for current browsers.
02Keep the palette tight
Icons are usually flat artwork — a low color count of 4 to 8 gives the cleanest, most faithful vector result.
Extract old Windows app icons as vectors for a rebranding project.
03Replace many sizes with one file
Download an SVG that covers every tab, bookmark, and home-screen size a browser might ask for.
Archive legacy icon sets in a format today's design tools can open.

Why convert ICO to SVG?
ICO is a Windows container format from the 1990s that bundles several fixed-size bitmaps — typically 16×16, 32×32, and 48×48 — into one file. Each embedded image is only sharp at its own size, which is why old favicons look crunchy on modern high-density displays and in large bookmark tiles.
Every current major browser accepts SVG favicons, and a single SVG covers all sizes and pixel densities at once. This converter reads an image from the ICO container and traces it into standard SVG paths you can reference from a single <link> tag.
Set expectations by the source: an ICO that only contains a 16×16 frame holds very little detail, so the result will look blocky if enlarged far beyond favicon size. Whenever possible, convert from the largest icon you have, and keep the original .ico around as a fallback for very old browsers.
“SVG is a language for describing two-dimensional graphics in XML. SVG allows for three types of graphic objects: vector graphic shapes (e.g., paths consisting of straight lines and curves), images and text.”
W3C, Scalable Vector Graphics (SVG) 1.1, §1.1
Where can I read more?
The output is standard SVG markup, defined by the following public specifications and references:
Favicon workflow
One vector in place of a bitmap container.
Trade a .ico full of 16×16 and 32×32 frames for a single SVG that every current browser renders sharply at any size.
Whole legacy icon sets
Drop in a folder of .ico files pulled from an old site or a Windows application and convert them in one pass.
One file, every size
A single SVG covers the tab, bookmark, and home-screen sizes the ICO container had to store as separate bitmaps.
Vector shapes out of pixels
The frame read from the container is traced into editable paths rather than embedded as an image inside SVG markup.
Tight palettes for flat icons
Icon artwork is usually flat, and 4 to 8 colors reproduces it most faithfully with the fewest paths.
No retained copies
Icon files are processed for the conversion and discarded afterwards; nothing is kept or reused.
