AI runs in your browser — your photos never leave your device
How it works
Drop your image
Drop a JPEG, PNG, WebP, or GIF. Nothing is uploaded. Your browser reads the file directly from disk using the File API.
AI removes the background
A small AI model (~43 MB) is downloaded to your browser on first use and cached. All inference runs locally — no server involved.
Download your result
Download as a transparent PNG, or choose a fill colour (white, black) to download as a JPEG. Use the slider to compare before and after.
Why remove backgrounds without uploading?
Most background removal services upload your images to their servers. For personal photos, product shots, or anything sensitive, that means giving a third party a copy of your files.
ClientSide uses a machine learning model compiled to WebAssembly that runs entirely inside your browser tab. The model is downloaded once (~43 MB) and cached locally. After that, every image is processed on your device with no internet connection required beyond the initial model download.

Frequently asked questions
Are my images uploaded to a server?
No. The AI model is downloaded to your browser once (about 43 MB), then all processing happens locally. Your images never leave your device.
Why is the first image slower to process?
On first use, the AI model (~43 MB) is downloaded from a CDN and cached in your browser. Subsequent images process from the cached model and are much faster.
What image formats are supported?
JPEG, PNG, WebP, and GIF. Output is always a PNG with transparent background, or a JPEG if you select a fill colour.
Can I use a white or custom background colour?
Yes. After removal, select White or Black. The result is composited in your browser and downloaded as a JPEG. The before/after preview updates live so you can see the result before downloading.
How is this different from other background removal services?
Most background removal services upload your photos to their servers and charge for high-resolution results. ClientSide runs the same type of AI entirely in your browser. Your images never leave your device, there's no cost, and no account required.
