How It Works
Everything runs directly on your device. Your images never leave your computer no uploads, no servers, complete privacy.
100% Private — Nothing Leaves Your Device
EraseBG.dev uses a technology called WebAssembly to run the AI directly inside your web browser. This means:
- Your images are never uploaded to any server
- All processing happens locally on your computer or phone
- Works offline after the first load (the AI model is cached)
- No account required, no data collected, completely free
1 Quick Start
Upload Images
Drag and drop your images onto the page, or click "Upload Images" to select files. You can process multiple images at once.
Auto-Process
The AI automatically detects the subject and removes the background. This happens instantly on your device nothing is sent online.
Download
Preview the result, use the compare slider, make edits if needed, then download as PNG (transparent) or WebP format.
2 Editor Features
Compare Mode
Use the slider to compare the original image with the transparent result side-by-side. Drag left and right to reveal each version perfect for checking edge quality around hair, fur, or complex shapes.
Editor Mode (Touch-Up Tools)
Switch to Editor mode for manual adjustments. The AI does a great job, but sometimes you need to fix small areas:
Remove parts that should be transparent. Left-click and drag to erase areas the AI missed.
Bring back parts that were accidentally removed. Paint over areas to restore the original pixels.
Controls: Scroll to zoom in/out • Right-click + drag to pan around • Adjust brush size with the slider
3 Settings Explained
Processor (GPU vs CPU)
Choose which part of your device does the image processing. Both options run locally this only affects speed and compatibility.
GPU (Graphics Card)
- Very fast: Processes images in under 2 seconds on most modern devices
- Best for: Desktop computers, laptops, newer phones and tablets
- Note: Uses your graphics card's memory (VRAM). May crash on very old devices.
CPU (Processor)
- Most compatible: Works on virtually every device, including older hardware
- Best for: Older phones, budget laptops, or if GPU mode crashes
- Slower: Takes 3-10 seconds per image depending on your device
AI Model Selection
Choose which AI model to use. Larger models produce better results but require more download time on your first use. The model is cached in your browser after downloading.
Fast Mode
Smallest download (~40MB). Loads quickly. Good for basic images, edges may be slightly rougher on complex subjects like hair.
Balanced Mode
Medium download (~80MB). Great balance of quality and speed. Handles most images very well including portraits and products.
Quality Mode
Largest download (~180MB). Highest precision for difficult subjects fine hair strands, fur, transparent glass, and intricate details.
4 Troubleshooting
Browser crashed or froze?
This usually means your graphics card ran out of memory. Open Settings (gear icon) and switch the processor to CPU. It's slower but much more stable.
Loading forever?
The first time you use the app, it downloads the AI model (40-180MB depending on settings). On slow connections, switch to Fast Mode in Settings for a smaller download.
Edges look rough?
Try switching to Quality Mode in Settings for better edge detection on hair, fur, and complex shapes. You can also use the Editor tools to manually touch up problem areas.
Want to start fresh?
Click the EraseBG.dev logo in the top-left corner to reset the app and clear all images. This won't affect your settings or the cached AI model.
? Frequently Asked Questions
Is this really free?
Yes, completely free with unlimited use. There are no watermarks, no account required, and no usage limits. The app runs entirely on your device so there are no server costs for us.
Do you store my images?
No. Your images never leave your device. All processing happens locally in your browser using WebAssembly technology. We have no way to see, access, or store your images.
Does it work offline?
Yes, after your first use. The AI model is cached in your browser, so you can use the app without an internet connection. Just make sure you've loaded the app at least once while online.
What image formats are supported?
You can upload JPG, PNG, and WebP images. The output is available as PNG (with transparency) or WebP format. There's no file size limit, but very large images may be slower to process.
Which browser works best?
We recommend Chrome, Edge, or Firefox for the best experience. Safari works but GPU mode may be less reliable. Make sure your browser is up to date for optimal performance.
