To change an image background colour, add your photo, let the AI find the subject (or choose the solid-colour method for plain backgrounds), pick a new colour, gradient, blurred original or your own picture, check the preview and press Apply. Free, private, and your images are never uploaded.
Add your images, check the live preview and download the result. Everything runs in your browser, so your images are never uploaded.

To change an image background colour, add your photo, let the AI find the subject (or choose the solid-colour method for plain backgrounds), pick a new colour, gradient, blurred original or your own picture, check the preview and press Apply. Nothing is uploaded; it all runs in your browser.
Swap a messy background for a clean colour, a gradient, a blurred version of the original or a picture of your own. The subject is cut out by AI on your device, then placed on the new background. It is a free tool from Websolindia, a New Delhi website design and SEO company that builds fast, image-optimised websites.
Unlike most online image tools, this one does not upload your pictures. An open-source neural network is downloaded to your browser once and then runs on your own device, so your photos are never sent to a server. You can process up to 30 images at a time and download them one by one or together as a ZIP.
Once your image is ready, you may also want the Remove Image Background Online, the Make Image Background Transparent or the Square Image Cropper Online. All of our free image tools are listed in the Image Background Change Tools collection and the Websolindia Image Converter.
Use this table to choose settings with confidence.
| Option | What happens | Good for |
|---|---|---|
| Solid colour | Subject on a single colour | Profile photos, products |
| Gradient | Two colours blended at an angle | Banners, thumbnails |
| Blurred original | The photo's own background, blurred | Portraits, depth effect |
| Your own image | Picture scaled to cover the canvas | Collages, scenes |
This is exactly what happens to your image, with no hidden step. You can check that nothing is uploaded by watching your browser's network tab while you use the tool.
| Step | What happens |
|---|---|
| 1. Cut out the subject | The AI (or colour key) separates the subject from the background exactly as in the Remove Image Background tool. |
| 2. Prepare the new background | A solid colour fills the canvas; a gradient is drawn at your angle; the blurred option blurs the original; your own picture is scaled to cover the canvas and centre-cropped. |
| 3. Composite | The subject is placed over the new background: result = subject × α + background × (1 − α). |
| 4. Encode | The result is saved as PNG, WebP or JPG. |
| Setting | Default | Choices | What it does |
|---|---|---|---|
| Method | AI — any photo (fast, 4.6 MB model) | AI — any photo (fast, 4.6 MB model); AI — better quality (44 MB model); Remove one solid colour (logos, plain backgrounds) | |
| Colour to remove | #ffffff | Any colour | Click the original image to pick the colour. |
| Colour tolerance | 12 | 1 to 60 | Higher removes more shades close to the colour. |
| Cut-out strength | 12 | 0 to 60 | Raise it to remove faint leftovers around the subject. |
| Edge softness (px) | 1 | 0 to 8 | Softens the cut-out edge so it blends naturally. |
| New background | Solid colour | Solid colour; Gradient; Blurred original; Your own image | |
| Colour | #2f6fb7 | Any colour | |
| Second colour | #ffffff | Any colour | |
| Gradient angle | 180 | 0 to 360 | |
| Blur amount | 18 | 2 to 60 | |
| Background image | None | Choose a file | |
| Save as | PNG (keeps transparency) | Same as the original; PNG (keeps transparency); WebP (smaller, keeps transparency); JPG (smallest for photos) | |
| Quality | 92 | 1 to 100 | Used for JPG and WebP output. 85–92 suits most images. |
| What | Formula | Notes |
|---|---|---|
| Composite | subject × α + background × (1 − α) | Per colour channel; α from the cut-out. |
| Gradient | colour₁ + (colour₂ − colour₁) × t | t runs from 0 to 1 along your chosen angle. |
| Cover scale | max(canvas width ÷ picture width, canvas height ÷ picture height) | Background picture fills the canvas, centred. |
| Component | Role | Where it runs |
|---|---|---|
| U²-Net + ONNX Runtime Web | Finds the subject | Your browser |
| Our compositor | Colour, gradient, blur or picture behind the subject | Your browser |
| Topic | Detail |

Add the photo, let the AI cut out the subject, choose 'Solid colour', pick a colour or a quick colour, and press Apply.
Yes. Choose Gradient for two colours and an angle, or 'Your own image' and select a file.
The original photo is blurred and the sharp subject is placed over it, which creates a studio-style depth effect.
No. The AI runs entirely in your browser.
Rules vary by country and application, so always check the official requirements. The quick colours include white, light grey and blue as common choices.
Yes, with the Remove Image Background Online or the Make Image Background Transparent.
Yes. It is free, needs no sign-up, adds no watermark and has no daily limit. It is provided by Websolindia.
No. Your images are read and processed inside your browser on your own device. They are never sent to Websolindia or anyone else, which is why the tool is safe for private photos.
No. New files are created from the pixels, so camera details, GPS location and other embedded metadata are not copied. Keep your originals if you need that information.
Up to 30 images per batch and 150 MB per image. Images above roughly 120 megapixels are declined with a clear message rather than freezing your browser.
Current versions of Chrome, Edge, Firefox and Safari on computers, phones and tablets. Large images and AI or AVIF features run faster on a computer.
