About Background Remover
This background remover uses an on-device AI segmentation model (U²-Net via ONNX Runtime Web) to detect the subject of your photo and delete everything behind it. The model is downloaded once by your browser and cached, then every removal runs locally on your own hardware.
Because nothing is uploaded, it is safe for portraits, product photos, ID pictures and client work. Export the result as a transparent PNG or flatten it onto a solid colour, then download instantly. A fast colour-based mode is available for images with a plain, uniform background.
How to use Background Remover
- Add your image
Drop a JPG, PNG or WebP file onto the canvas, or click to browse. The AI model downloads automatically the first time (a few megabytes, cached afterwards).
- Remove the background
Click Remove Background. The model produces a soft alpha matte around the subject; use the edge refine slider if you need a cleaner outline.
- Download the PNG
Preview the cutout on a transparent checkerboard, optionally add a solid background colour, then download a transparent PNG at full resolution.
Frequently Asked Questions
Is this background remover really free and private?
Yes. The AI model runs inside your browser using WebAssembly and WebGL, so your image never leaves your device. There is no account, no credit system, no watermark and no file-size limit. The only download is the one-time model file, which your browser caches.
Which images work best for automatic background removal?
Photos with a clear subject — people, pets, products, cars — produce the cleanest cutouts. High-contrast edges and reasonably lit subjects work best. Very fine details such as loose hair or fur may need the edge refine slider, and a plain background lets you use the faster colour mode.
Does it work on mobile phones?
Yes, the tool works on modern Android and iOS browsers. On lower-end phones the AI model can take a few seconds per image and uses more memory; the lightweight colour mode is instant and a good fallback for simple backgrounds.
What format is the result?
You get a transparent PNG, which preserves the alpha channel needed for cutouts. You can also flatten the result onto white or any custom colour before downloading, or send it to the Image Converter to produce a WebP or AVIF with a smaller file size.
