About Background Remover
Remove image backgrounds without uploading anything
Most background-remover websites upload your photo to their servers, run the model there, and hand back a result. That works — but for product photos, portraits, or anything internal, you probably don't want a copy sitting on a third party's disk.
This tool uses the @imgly/background-removal WebAssembly build, which ships a compact ONNX model that runs entirely in your browser. Your photo is never uploaded — the model downloads to your browser cache on first use (about 40 MB) and every subsequent run is instant and offline-capable.
Free tier vs Pro
- Free: output is downscaled to 1024 px on the longest side before the model runs, which keeps memory usage predictable on lower-end laptops and phones.
- Pro (coming soon): runs at full source resolution — useful for print-quality product shots and marketing assets.
Tips for good results
- Portraits and product photos on plain backgrounds work best.
- Hair and fur may show soft edges — that is the model's honest output, not a bug.
- If you need pixel-perfect edges, do a final polish in Photoshop / Affinity / GIMP using the model output as a starting mask.
Frequently asked questions
No. Both the model and the image processing run in your browser via WebAssembly. Your photo never leaves your device.
The AI model is about 40 MB and has to download the first time. Your browser caches it after that, so subsequent runs start instantly.
The free tier downscales output to 1024 px on the longest side. Pro users get full-resolution output. Downscaling keeps memory usage predictable on mid-range hardware.
Any format your browser can decode — JPG, PNG, WebP, GIF, BMP. Output is always a PNG with alpha transparency so the removed background reads as transparent when you use the image elsewhere.
Yes — once the model is cached, the tool works without an internet connection. Useful for handling sensitive assets on flights or in air-gapped environments.
