My SVG has no width or height. What size does it use?

The viewBox, scaled against whichever of the two attributes was supplied. With neither attribute and no viewBox it falls back to the CSS default for a replaced element, 300 × 150, and says so on the page, set an exact width if that is not what you wanted.

Is there a size limit?

12,000 px per side and 40 million pixels in total. Past either, it tells you instead of handing back an empty PNG.

How it works

SVG to PNG: Rasterise at 1×, 2×, 4× or an Exact Width

Rasterise an SVG to PNG at 1×, 2×, 4× or a width you type. Drop a file or paste the markup, an SVG carrying only a viewBox still sizes correctly.

What this does

Export at 1×, 2× or 4×, or type a pixel width and let the height follow the ratio
Drop an .svg file, or paste the markup into the editor and rasterise that
Reads a width or height given in px, pt, pc, in, cm, mm or q, and falls back to the viewBox
Transparent or white background, with the PNG size shown before you download it
Refuses anything past 12,000 px a side or 40 million pixels rather than returning a blank canvas

FAQ

An SVG rendered through an image element is drawn in an isolated context. External stylesheets and @font-face files pulled in by URL are never fetched, so any family the machine does not already have falls back to a system default. The fix is to convert text to outlines in your editor before exporting, or to embed the font inside the SVG as a base64 data URI. The same isolation applies to artwork: an image element pointing at an https:// URL comes out blank, and a cross-origin resource that does load taints the canvas and blocks the PNG export outright.

An SVG has no resolution of its own, the numbers in its width, height or viewBox are only a coordinate space. Exporting at 1× reproduces that space pixel for pixel, which for an icon is often as little as 24 px across. 2× suits a retina screen, 4× or an explicit width suits print and app icons. Choose the size here rather than enlarging the PNG afterwards: rasterising at the target size is sharp, and resampling a small PNG is not.
