Make a colour transparent by clicking
For logos, scans, product shots on white — anything with a fairly even background. You click, that colour goes transparent, and you stay in control of exactly how much is removed.

How it works
- Drop an image with a reasonably even background.
- Click on the background. If too little or too much disappears, adjust the tolerance — how close to the clicked colour a pixel must be to disappear as well.
- Keep clicking on any patches left over, then download the transparent PNG.
Why nothing is uploaded
Every operation on this page is done by code running inside your browser tab, using the same engine that renders web pages. The file is read from disk into your tab’s memory, transformed there, and written back out as a download. It is never sent anywhere — not to us, not to a third party.
Verify it yourself
- Open your browser’s developer tools (F12) and select the Network tab.
- Load your file and run the tool.
- The only requests you will see fetch the tool’s own code — and, for a few heavy tools, their open-source engine from a public CDN — plus one small page-view ping to loreatec.jp (page address and title, nothing more). None of them carry your file.
Frequently asked questions
How is this different from the AI background remover?
That one guesses where the subject is and does everything in one go, which works on complicated photos but gives you no say in the result. This one removes exactly the colour you point at, so it is predictable and correctable — much better for logos, scans and flat backgrounds, and useless on a busy photograph.
What does the tolerance actually change?
How different a pixel may be from the colour you clicked and still be erased. A photographed white background is never one white: it has shadows and a colour cast. Too low and you get speckles left behind; too high and it eats into the subject. Around 30 suits most scans.
Why is part of the background still there?
By default only the region connected to your click is erased, so a background split into separate pieces — the gap inside a handle, the space between an arm and the body — needs a click each. Switching to “that colour across the whole image” does all of them at once, at the risk of also hitting matching pixels inside the subject.
Why is there still a faint outline?
The pixels along the edge are a mix of subject and background colour, so no setting sorts them perfectly. “Soften the cut edge” makes the pixels next to an erased area partly see-through, which removes most of the halo. A hard-edged graphic will not need it; a photograph usually will.
Is the image uploaded?
No. It is opened in this tab and every click is processed here. There is no model to download either, so this tool works with the connection off from the very first use.
