Your logo is trapped in a white box — two ways out

2026-09-28

You place a logo on a coloured slide, a dark website header, a product banner — and it shows up inside a hard white rectangle. The logo is fine; the file is a JPG, and somewhere along its history the transparency was flattened into white pixels that are now permanently part of the image.

How logos end up welded to white

JPG cannot store transparency, so the first time somebody saved that logo as JPG — to email it, to shrink it, by habit — every transparent pixel became a white one (the format map covers which formats do this). Nothing warns the next person; the white box only appears when the logo lands on a background that isn't white.

Way out #1: find the original — costs nothing, loses nothing

Before repairing anything, ask whether a transparent original still exists: a PNG or SVG from the designer, a brand-assets page, the files attached to the original delivery email. Any of those beats the best repair, because the true edges are still in the file. If you find an SVG, convert it to PNG and you have a clean transparent raster at any size you need — done.

Way out #2: remove the white — the honest repair

When the white-boxed JPG is genuinely all that survives, our background remover erases the plain background to transparency, right in your browser: it spreads inward from the edges through connected background colour, stopping at the logo's boundary, with a brush for tidying leftovers. Flat-colour logos on white repair well. The honest caveats: anti-aliased edges were blended into white and can keep a faint halo — visible mostly on dark backgrounds — and any white inside the design that touches the outer background will be treated as background.

Keep it from happening again

Save the repaired logo as PNG — export as JPG and you have rebuilt the white box. Then keep one master copy somewhere findable, so the next person edits the transparent version instead of the flattened one.

What we deliberately don't do

We don't redraw edges with AI or vectorise the logo. The repair recovers what the pixels still contain; it does not invent what they lost. For a pixel-perfect result at any size, the answer is the original vector file — which is why way #1 comes first.

The short version

• The white box is flattened transparency — a past save-as-JPG, now baked in.
• First choice: hunt down the transparent original (PNG/SVG). It always wins.
• Second choice: erase the plain background in the browser; expect minor halos on dark grounds.
• Save the result as PNG, and keep a master copy this time.
