Turn the white background of a logo, a scanned signature, a product shot or a screenshot into transparency and download a PNG. Edges stay smooth and the white fringe is cleaned off, so the result looks right on dark backgrounds too. Free, no watermark, and your image never leaves your browser.
No image yet. You can also drop a file on this box or paste one (Ctrl+V).
Background: auto. Click the image to clear any area that is left.
The pixels along the edge of a logo are a blend of the logo color and the white behind it. Tools that only delete pure white keep those pale blended pixels, and they show up as a light fringe as soon as you put the image on a dark page. This tool gives edge pixels partial transparency instead, and then takes the white back out of their color (it solves pixel = alpha × color + (1 − alpha) × white for the color). Set Preview on to Black to check the edges before you download.
Pick or paste an image. Outer area clears the background color connected to the edges of the image and keeps the same color inside the subject (the white of an eye, white text on a dark logo). Everywhere clears that color anywhere, which suits a black signature or a stamp with enclosed gaps. Or stay on Outer area and click each enclosed gap. Tolerance sets how far a pixel's color can be from the background and still be removed. Edge softness sets the width of the color band that fades out instead of being cut, which keeps curves smooth.
Your browser decodes the image onto a canvas. The background color is either the one you choose or the most common color along the four edges. Every pixel gets a color distance to it. A flood fill from the edges (or from each point you click) makes the matching pixels transparent. Up to 3 pixels around that area fade out across the softness band, and their color is unmixed from the background color. The PNG keeps the original size in pixels. Nothing is uploaded, and it works offline once the page has loaded.
Other ways in: make image background transparent. Next steps: crop or resize the PNG, trace it to SVG, make a favicon from it, or put it on a photo with add logo to image. To sign a PDF with a transparent signature, use sign PDF.
Need web page elements or HTML cards with a transparent background? The Shotmint API renders a URL or raw HTML in Chromium, and omit_background=true returns a PNG with transparency wherever the page has no background:
curl "https://shotmint.creasework.com/v1/screenshot?url=https://example.com&omit_background=true&format=png" -H "X-API-Key: YOUR_KEY" -o page.pngEach screenshot or PDF is 1 credit. €5 buys 2,000 with no subscription, and credits never expire.

Is my image uploaded? No. Everything runs in JavaScript on this page.
Why are parts of my logo disappearing? They are close in color to the background. Lower Tolerance, or switch Remove to Outer area so only the background that touches the edges goes.
There is still a light fringe around the edges. Raise Edge softness a little, and check the result with Preview on Black. JPEGs often need a Tolerance of 15 to 25 because compression adds noise around edges.
Can I get a JPG? No: JPG has no transparency. Use PNG (lossless) or WebP (smaller files, lossless here too in most browsers).
Does it work on photos of people? Only when they stand in front of a plain, evenly lit backdrop. This is a color-based tool, not an AI cut-out tool.
