Loading the tool…
To remove an image background, add your photo, wait a few seconds while the AI finds the main subject, check the preview on the checkerboard and press Apply to download a transparent PNG. The AI runs inside your browser, so the photo is never uploaded. The first use downloads a small 4.6 MB model.
Cut the subject out of a photo and drop the background, free. A neural network runs on your own device to find the main subject, so product photos, portraits and pets stay private. 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 Make Image Background Transparent, the Change Image Background Color or the Circle 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.
| Method | Best for | Download | Notes |
|---|---|---|---|
| AI fast | Most photos with a clear subject | 4.6 MB, once | Quickest; may miss thin parts |
| AI better | Portraits, harder scenes | 44 MB, once | Cleaner edges and limbs; slower |
| Remove one colour | Logos, scans, plain backgrounds | None | Instant; only that colour is removed |
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. Read and decode | The photo is decoded on your device. |
| 2. Prepare the input | The image is scaled to 320 × 320 pixels and its colours are normalised the way the U²-Net model expects. |
| 3. Run the AI in your browser | ONNX Runtime Web runs the U²-Net network with WebAssembly and returns a 320 × 320 map of how likely each pixel is to be part of the subject. |
| 4. Build the mask | The map is stretched to its full range, scaled up to your photo's size, then turned into transparency with a smooth threshold you can adjust. |
| 5. Soften and save | Edge softness blurs the alpha channel slightly; the cut-out is saved as PNG or WebP with transparency. |
| 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. |
| Save as | PNG (transparent) | PNG (transparent); WebP (smaller, transparent) |
| What | Formula | Notes |
|---|---|---|
| Normalisation | (pixel ÷ max − mean) ÷ std per channel | mean 0.485, 0.456, 0.406; std 0.229, 0.224, 0.225. |
| Mask range | (p − min) ÷ (max − min) | Stretches the model's output to 0–1. |
| Alpha | smoothstep((mask − low) ÷ (high − low)) | Low rises with the cut-out strength setting. |
| Component | Role | Where it runs |
|---|---|---|
| U²-Net (small or Silueta) neural network | Finds the subject | Your browser |
| ONNX Runtime Web (WebAssembly) | Runs the model | Your browser |
| Our mask code | Threshold, softness, transparency | Your browser |
| Topic | Detail |
|---|---|
| Images per batch | Up to 30 at a time |
| File size | Up to 150 MB per image |
| Image dimensions | Up to about 120 megapixels; larger images are declined to protect your browser |
| Privacy | Images are processed in your browser and never uploaded |
| Browsers | Current Chrome, Edge, Firefox and Safari (WebAssembly is needed for AVIF, HEIC, TIFF and AI tools) |
| Metadata | EXIF and location data are not copied into new files |
No. The AI model is downloaded to your browser once and then runs on your own device. Your photo is never sent anywhere.
It is good for clear subjects against plain or contrasting backgrounds. In our checks the small model matched its reference output closely, but it can miss thin parts like raised arms, and the better-quality model handles those more cleanly.
The first time, your browser downloads the model (4.6 MB, or 44 MB for the better one) and starts the engine. Later images are much faster.
The AI picks the most prominent object. Crop the photo first so your subject dominates, or use the colour method for plain backgrounds.
Yes. Use the Change Image Background Color to pick a colour, gradient, blurred original or your own picture.
PNG or WebP with a transparent background. JPG cannot store transparency.
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.
