The white box is a shape, not a setting.

It is a rectangle in your file. Find it, or trace from a source that never had one.

Your source PNG had a solid white rectangle, and the trace faithfully reproduced it

Transparency in a PNG is a real property, and plenty of PNGs that look transparent do not have it. The classic case is an image saved from a screenshot or copied off a web page: it was displayed on a white page, so the saved pixels are white — genuinely, not apparently. A tracer has no way to know you consider that background rather than artwork. It sees a large white region with a clear boundary and returns it as a filled rectangle, which is the correct reading of what you gave it. The white did not appear during conversion; it was in the file before you started.

How to confirm it

Check the source first
Open the PNG in an editor. A real transparent area shows a checkerboard, not white.
In the SVG
It is usually the first element — a `<rect>` or a path covering the whole viewBox.
Selection test
Click the white area in Illustrator or Inkscape. If it selects, it is an object and can be deleted.
On a dark page
Drop the SVG onto a dark background in a browser. The box becomes obvious immediately.
Not the cause
Export settings, "save as SVG" options, or the viewer's background colour.

The fix

1
Look at the original, not the SVG

If the source PNG has real transparency, the trace will too. If it does not, no export setting will invent it.

2
Get a source with real alpha

Re-export from the design file with a transparent background, or remove the background from the raster before tracing.

3
Trace and verify on dark

Upload it here and check the preview against a dark surface — a surviving box is visible instantly.

FAQ

Can I just delete the white rectangle?

Often yes, and it takes seconds in any vector editor — select it and delete. It fails when the artwork itself contains white elements that were merged into the same traced region, in which case deleting takes parts of the design with it. Fixing the source is more reliable.

Why does it look transparent in my file browser?

Because most previews render on white. A white rectangle on a white preview is invisible. Viewing on a dark background is the fastest way to tell, and it is worth doing before you upload anywhere.

Does this matter for printing?

A great deal on anything that is not white. On a coloured garment, a mug or a sticker, the box prints as a visible white panel around the artwork. It is the most common reason print-on-demand platforms reject an upload.

Will removing the background lose quality?

Not if it is done before tracing. Removing a flat background from a raster is lossless for the artwork itself, and the trace then has a clean edge to follow — which usually improves the result rather than degrading it.
