What is SVG?
SVG (Scalable Vector Graphics) is an XML-based vector image format. Instead of pixels, an SVG describes shapes, paths, fills, and strokes mathematically, so it can be rendered at any size without losing quality.
SVG is the standard vector format for the web. It is supported natively by every modern browser, can be styled with CSS, animated with JavaScript or SMIL, and is generally a fraction of the size of an equivalent raster image.
What is ICO?
ICO is the Windows icon container format used for favicons, application icons, and desktop shortcuts. An ICO file can hold one or more raster images (typically 16×16 up to 256×256) inside a single file.
SVG vs raster formats
Vector graphics (SVG) and raster graphics (PNG, JPG) solve different problems. The right format depends on what the image will be used for.
| Feature | SVG | PNG / JPG | ICO / ICNS |
|---|---|---|---|
| Scaling | Resolution-independent | Blurry when enlarged | Pre-rendered at fixed sizes |
| File size | Small for shapes and icons | Grows with resolution | Bundle of pre-sized rasters |
| Editing | Editable as text or in vector tools | Pixel-level editing only | Edit each size, then repack |
| Animation | CSS, SMIL, JavaScript | Limited (animated PNG/GIF) | Not supported |
| Transparency | Yes | PNG yes, JPG no | Yes (PNG-based) |

Frequently asked questions
What sizes does the ICO contain?
The converter packs every standard ICO slot up to your target size into a single file: 16, 32, 48, 64, 128, 256. Most browsers and Windows tools pick the right size automatically based on context.
What size should I pick for a favicon?
32 is a safe default for browser tabs and bookmarks. Pick 256 if you want every standard size bundled. Windows will use the largest for shortcuts, taskbar pins, and desktop icons.
Can I use a transparent background in an ICO?
Yes. ICO supports per-pixel alpha and the converter preserves transparency from the SVG by default. Pick a solid background color only if you want to fill the see-through areas.
