Local Browser Processing vs. Cloud Removers
RemoveG eliminates data security vulnerabilities and subscription meters by running neural inference directly on your hardware.
Conventional Cloud Tools
Remote Server Uploads
- ✕ Uploads original photos to external cloud servers
- ✕ Data exposure risk for confidential and client photos
- ✕ Downscales free images to 500px previews with paywalls
- ✕ Slower on constrained internet connections

Frequently Asked Questions
Are my images ever uploaded to an external server or cloud service?
No. RemoveG processes images 100% locally directly in your browser tab. Your photo is decoded into local memory, evaluated by an on-device neural network via WebAssembly or WebGPU, and composited onto a local HTML Canvas. It is never sent to any remote server or external image-processing API.
Does RemoveG downscale my photos or restrict high-resolution downloads?
No. Unlike cloud services that give you a 500x500px preview and charge subscription credits for full-resolution exports, RemoveG does not gate your image quality. The browser canvas renders and exports your photo at its native camera resolution (up to 25 MB and 4K resolution) free of charge with zero watermarks.
What machine learning model powers RemoveG?
RemoveG uses IS-Net (InSPyReNet), a salient object detection neural architecture trained for high-resolution edge extraction, hair preservation, and continuous alpha matting. The model executes directly in your browser using ONNX Runtime Web.
Why does my cutout have a solid background when saved as JPG?
The JPG / JPEG format specification does not support an alpha transparency channel. If you export as JPG, transparent pixels are replaced with your chosen solid background color (such as Amazon-standard pure white #FFFFFF). To preserve a completely transparent cutout for graphic design overlays, always export as PNG or WebP.
Which image formats are supported by RemoveG?
You can upload JPG, JPEG, PNG, and WebP images up to 25 MB. The final cutout can be exported as a transparent PNG, modern WebP (25–35% smaller for websites), or crisp JPG with your choice of solid backdrop or gradient.
What hardware, operating system, or browser do I need?
RemoveG works across all modern browsers including Google Chrome, Apple Safari (macOS and iOS), Microsoft Edge, and Mozilla Firefox. Devices supporting WebGPU achieve sub-second inference speeds, while devices without WebGPU automatically use multi-threaded WebAssembly (WASM).
Can I use the exported cutout images commercially?
Yes. You retain 100% ownership and copyright of your original images and the resulting cutouts. RemoveG is free for both personal and commercial use (e-commerce listings, marketing assets, portraits, client projects, etc.).
How do the manual Erase and Restore touch-up brushes work?
In the interactive studio editor, you can fine-tune AI results. The Erase brush removes stray background artifacts or shadows that were mistakenly retained, while the Restore brush samples your original photo and paints back delicate clipped details like fine hair, jewelry, or sunglasses.
