PNG, JPG, WebP or GIF — made transparent in your browser, never uploadedAbout making an image transparent
A logo on a white box, a signature on paper, a drawing on a coloured background — often you want only the drawing, with nothing around it. Then it sits nicely on a website, a slide, a document or a T-shirt design.
This tool does it with one click. Click the colour you want to remove, and every pixel of that colour becomes see-through. Set how close a colour must be (the tolerance), soften the edges, and check the result on a checkerboard, white, black or pink. Download a PNG — the image format that keeps transparency.
When you open a picture, the tool already picks the most common colour at its edges. In a logo or a scan, that is almost always the background.
Everything happens in your browser. Your picture is never uploaded.
Features
- Click to pick the colour — or let the tool guess the background colour
- Tolerance — remove only the exact colour, or also the shades close to it
- Smooth edges — round shapes get soft edges, not steps
- No white halo — the old background colour is taken out of the edge pixels
- Everywhere, around it, or one patch — keep white inside a logo if you want
- Checkerboard preview — and white, black or pink to check the edges
- Trim the empty space — the PNG ends where your picture ends
- Private — nothing is uploaded
What the tolerance does
Each pixel gets a distance from the colour you picked: 0 % is the same colour, 100 % is as far as black is from white. Pixels closer than the tolerance become fully transparent. Pixels a little further away — inside the smooth edges band — become partly transparent. All other pixels stay as they are.
With white picked, a tolerance of 15 and smooth edges at 30 (the defaults):
| Pixel colour | Distance from white | Result |
|---|---|---|
| Almost white (250, 250, 250) | 2.0 % | Transparent |
| Light grey (240, 240, 240) | 5.9 % | Transparent |
| Paper grey (225, 225, 225) | 11.8 % | Transparent |
| Grey (200, 200, 200) | 21.6 % | 55 % visible |
| Light pink (255, 200, 200) | 17.6 % | 22 % visible |
| Mid grey (160, 160, 160) | 37.3 % | Stays as it is |
| Black (0, 0, 0) | 100 % | Stays as it is |
The smooth band is the smooth-edges value × 0.4 per cent wide: at 30 it reaches from 15 % to 27 %. Set smooth edges to 0 for hard edges (pixel art, QR codes).
Everywhere, around it, or one patch
- Everywhere in the picture removes the colour wherever it is. Good for a logo where the holes in letters like "o" and "a" must be see-through too.
- Only the background around it removes the colour only where it touches the edge of the picture, and everything joined to that. White eyes in a cartoon, or a white shirt inside a drawing, stay white.
- Only the patch I click removes just the area you click on, and everything of that colour joined to it.
Tips for a clean result
- JPG pictures have noise around edges and in flat areas. Raise the tolerance to 20–30 so the whole background goes.
- A white halo on a dark page? Keep "Remove the colour fringe" on, raise smooth edges, and check on the black preview.
- Parts of your logo vanished? Lower the tolerance, or choose Only the background around it.
- Scanned signatures: pick the paper colour, tolerance about 25, then trim the empty space. See also Signature Maker.
- A busy photo (people, pets, products) has no single background colour. Use the Background Remover for that.
Frequently asked questions
How do I make the white background of a picture transparent?
Open the picture. The tool usually picks the white at once — if not, click the white area. Keep the tolerance at about 15, check the checkerboard preview, and click Download PNG.
Why must the result be a PNG?
JPG cannot store transparency: see-through parts turn white or black. PNG keeps them see-through, so the file works on any background.
Can I remove a colour other than white?
Yes. Click any colour in the picture, or choose one in the colour box. Green screens, blue boxes and grey paper all work.
Why are there still light pixels around my logo?
Those are edge pixels mixed from the logo and the background. Raise Smooth edges and keep Remove the colour fringe on. Check the result on the black preview.
Can I make a photo of a person transparent?
Only if the background is one plain colour. For a normal photo, use the Background Remover, which finds the person by itself.
Is my picture uploaded?
No. Everything is done in your browser. The picture never leaves your device.
