Your SVG blurs because it is not vector.
A real SVG cannot pixelate. If yours does, there is a raster image hiding inside it.
There is a base64 raster image inside the file, wrapped in vector packaging
A true SVG is a set of mathematical paths and it is physically incapable of blurring — you can scale it to a billboard and the curves are recomputed at every size. So if your file pixelates, it does not contain paths. What it contains is an `<image>` tag holding a PNG or JPEG encoded as base64 text, wrapped in an `<svg>` element. It opens in Illustrator, it has an .svg extension, and it is a photograph in a costume. This is far and away the most common thing sold as "vectorized" by cheap converters, because embedding a raster takes no work and produces a file that passes every superficial check.
How to confirm it
- The ten-second test
- Open the .svg in a plain text editor. Search for `<image`. If it is there, the file is raster.
- File size
- A real traced logo is usually 5–200 KB. A file of several MB is carrying a photo.
- In Illustrator
- Click the artwork. If it selects as one object with a bounding box and no anchor points, it is a placed image.
- Zoom test
- Zoom to 1600% in a browser. Real paths stay crisp; an embedded raster shows pixels.
- What it is not
- Not a rendering bug, not a browser issue, and not fixable by re-saving as SVG.
The fix
Search the file for `<image`. Finding it settles the question — nothing else needs testing.
Use the highest-resolution PNG or JPG you have, not the fake SVG. Re-tracing the embedded copy inherits its limits.

FAQ
Not by re-saving. The SVG wrapper adds nothing to trace from — you have to trace the raster inside it, which means extracting that image or going back to the original. Starting from the original is always better, because the embedded copy has usually been resized and recompressed at least once.
Because it is nearly free. Genuine tracing is computation; wrapping a PNG in an `<svg>` element is a string operation, and the output passes a file-extension check, opens in a vector editor, and looks correct until someone scales it. It is the cheapest way to answer a "convert to SVG" request.
The preview shows the path count before you pay. A traced piece of flat art is typically tens to a couple of hundred editable paths. A wrapper has zero paths and one image tag, and no path count to show.
No — printing is where it gets worse, not better. A print RIP resamples at the physical size, so a raster that looked acceptable on a monitor becomes visibly soft at any real dimension. Cutting machines fail harder still, since there are no contours to follow.
