How Image Background Remover Works
AI-powered background removal that runs entirely in your browser — no upload, no server, true straight-alpha transparency.

- 1
Upload and decode
Drag and drop or click to browse. PNG, JPG, WebP, AVIF, and HEIC are all supported. Your image is read locally — never transmitted anywhere. Magic-byte validation confirms the file type, and HEIC files are converted via a local WebAssembly decoder.

On-device AI inference
The neural network runs entirely in your browser via Transformers.js. On supported hardware, WebGPU executes on your GPU. ORMBG (Fast mode) delivers speed; BiRefNet (Best Quality mode) preserves hair, fur, and fine edges at the cost of a larger model download.

Export with straight alpha
The result is encoded as PNG, WebP, or AVIF with straight (non-premultiplied) alpha — the correct format for Photoshop, Figma, and Canva. No black halos. An automatic validation pass confirms alpha integrity before the download is offered.
Frequently asked questions
Does the image ever leave my device?
No. The AI model runs in your browser via WebAssembly and WebGPU. Your image never leaves your device — there is no server that receives or processes it.
What is the maximum image size?
Up to 4096 × 4096 px at full resolution. Larger images are downscaled for inference then upscaled back — so you still get a full-res export.
Why does my result look different in Photoshop vs the browser preview?
Browser previews composite transparent pixels over a white or gray background. Photoshop shows the checkerboard (true transparency). If you see black halos in Photoshop, another tool used premultiplied alpha — our tool always uses straight alpha which is correct for professional software.
Which mode should I use — Fast or Best Quality?
Use Fast for product images and simple subjects. Use Best Quality for portraits, hair, fur, and anything with complex edges where fine detail matters.
