Remove a solid-color background from an image

The job

A logo came as a JPG on a white box, or a product shot sits on a flat studio backdrop. You need the subject on transparency so it drops onto slides, thumbnails, or a site without the rectangle around it.

How to do it

Open the image, click the background in the preview (the clicked color fills in for you — or type a hex/RGB value), and set the tolerance. A small value removes only near-identical pixels; raise it until an uneven background is fully gone, then download the PNG.

• The result counter shows how many pixels were removed — a quick sanity check that you are cutting the background and not the subject.
• If nothing was removed, the tool says so instead of handing back an unchanged file.

Worked example

A dark logo on a pure-white card: pick white, tolerance ~30, and the card disappears while the logo stays. A slightly off-white scan may need ~60.

Limits

This is color-key removal, not AI subject detection — it works where the background is one flat-ish color and fails on gradients, shadows, and busy scenes. Edges are a hard cut with no feathering, so a thin halo can remain on anti-aliased artwork; zoom in and adjust tolerance. JPG input exports as PNG up to 25 MiB.
