How to Remove Background from an Image
unbg makes background removal simple, free, and private. Here is exactly how it works - from upload to download in under 30 seconds.
Upload Your Images
Open unbg.tech and drag your images onto the upload area, or click to browse your files. You can upload multiple images at once.
- Supported formats: PNG, JPG, JPEG, WebP, and HEIC
- Max file size: 20MB per image
- Multiple files: Upload as many images as you need - they are processed one at a time for best quality
- Mobile friendly: Works on phones and tablets too - take a photo and upload directly
AI Removes the Background
Once uploaded, unbg's AI model runs directly in your browser. The neural network analyzes your image and precisely separates the subject from the background.
- 100% browser-based: The AI model runs locally using WebAssembly - your images never leave your device
- First-time setup: On the first use, the AI model (~80MB) downloads and caches in your browser. Subsequent uses are much faster
- Smart edge detection: Handles hair, fur, transparent objects, and complex edges with precision
- No internet needed after setup: Once the model is cached, you can use unbg even without an internet connection
Download Your Transparent PNG
Your processed image is ready instantly. Download it as a high-quality transparent PNG - ready for use in e-commerce listings, social media, presentations, or any design project.
- Full resolution: No quality loss or downscaling - you get the same resolution as your original
- No watermarks: Unlike other tools, unbg never adds watermarks to your images
- Transparent PNG: Industry-standard format supported everywhere
- Unlimited downloads: No credit system, no daily limits, no restrictions
Why unbg Is Different
Most background removal tools upload your images to their servers for processing. unbg takes a fundamentally different approach - the AI runs entirely in your browser.
Complete Privacy
Your images are processed locally and never uploaded to any server. Ideal for sensitive photos like ID documents, passport photos, or confidential product images.
Truly Free
No credit system, no daily limits, no premium tiers. Every feature is available to everyone at no cost - full resolution, no watermarks, unlimited usage.
Fast & Offline-Ready
After the initial model download, processing takes just a few seconds. The cached model even works without an internet connection.
Works Everywhere
Works on any modern browser - Chrome, Firefox, Safari, Edge - on desktop, tablet, or mobile. No app to install.
Common Questions
Why is the first use slower?
On your first visit, unbg downloads the AI model (~80MB) to your browser. This is automatically cached so future visits are much faster. Think of it like installing a tiny app in your browser.
Does it work on mobile?
Yes. unbg works on any modern mobile browser. You can take a photo with your phone camera and upload it directly. Processing may be slightly slower on older devices.
Is it really private?
Absolutely. The AI model runs using WebAssembly in your browser. Your images are never sent to any server. You can verify this by checking your browser's network tab - no image data leaves your device.
What image quality can I expect?
unbg outputs full-resolution transparent PNGs with no quality loss. The AI handles complex edges including hair, fur, and semi-transparent objects. Results are comparable to premium tools like remove.bg.
