Why does my “transparent PNG” logo still have a white box?

Distinguish the viewer from the file

Open the export in an editor that displays transparency and place it over both a dark and a colored background. Some viewers show a transparent canvas as white; others display genuinely white pixels. Test the asset itself rather than interpreting the preview’s background. Also inspect whether only the outer canvas was removed while white islands remain between letters or inside the symbol.

A photographic mockup can contain a correct-looking logo on white paper without providing a reusable isolated mark. Keep the original concept for design review, but ask for a separate approved production asset. CartVisual Logo studio generates raster concepts; a requested isolated mark still needs output inspection.

Review the export evidence

Do not indiscriminately erase every white pixel: an intentionally white logo version would disappear. Separate the artwork’s fill colors from its background.

Ask the reviewer to record the actual transparency result, not just “PNG” or “RGBA.” A full alpha channel can still contain only opaque samples. PNG can also carry transparency through its tRNS information, so the absence of a separate full alpha channel is not by itself a failure. The PNG specification describes these representations; an editor that correctly decodes the file can show the resulting transparency without requiring the merchant to edit chunk data.

For the fictional teal mark, inspect the outer canvas, the intended inner opening, one antialiased edge and an intentional white letter separately. The canvas and opening should reveal the chosen background where the design calls for a cutout; the white letter should retain its approved fill. Repeat on both approval backgrounds with the exact final export. If the exported file works but the webpage shows a white box, inspect the actual delivered version and page treatment before erasing more pixels. Use vector cutout review for path geometry and color-version review for intentional white artwork.

Use two approval backgrounds

For an illustrative teal symbol, test the final PNG on the store’s dark navigation bar and its pale packaging preview. Examine a small display size and the edge at a useful zoom. Record which logo version is intended for each surface. A black-on-transparent export and a white-on-transparent export are separate deliverables, even when both come from the same master.

Use the logo delivery review CSV as a manual record. Its sample row is fictional. Replace it with your own authorized evidence; the worksheet does not connect to or change any external account.

Keep concept and deliverable labels honest

Save the raster concept, transparent web export and any externally redrawn vector master under distinct names. Do not call the concept a transparent asset until the actual pixels pass the test. Transparency also does not prove vector editability, font rights or trademark clearance. Approve those properties separately before commercial rollout.
