Background remover — AI cutout for people & objects
Run the BRIA RMBG-1.4 segmentation model in your browser via transformers.js + ONNX Runtime Web to cut the subject out and export a transparent PNG. The model downloads once and works offline afterwards. Supports batch processing with a ZIP download. Images never leave your device.
How to use
Drop the images whose subjects you want to cut out (batch supported). The first run downloads the BRIA RMBG-1.4 model (~44 MB); subsequent runs hit the cache. Inference uses transformers.js + ONNX Runtime Web. Each image is exported as a transparent PNG of the subject. Download individually or as a ZIP. WebGPU-capable browsers run dramatically faster.
FAQ
- Are images uploaded?
- No. The model runs inside your browser, so images and outputs never leave the device.
- How big is the model download?
- BRIA RMBG-1.4 weights are ~44 MB; cached after first use.
- Why is it slow?
- It may be running on CPU. A recent WebGPU-capable browser (Chrome / Edge) speeds it up significantly.
- Edges look rough — what can I do?
- Fine details like hair, or images with low subject/background contrast, are challenging. RMBG-1.4 is a general model — a domain-specific (e.g. product) model could do better.
- Is commercial use OK?
- Follow the BRIA RMBG-1.4 license. Commercial use may require additional terms — check the official license.

Add image background — solid color or another photo overlay
Composite a solid color (hex code) or another image as the background for transparent PNGs and photos. Runs on the local Canvas — nothing leaves your browser. Either fill the original transparent areas or add padding on all sides and let the background wrap around. Batch-process and download as a ZIP. Output keeps the source format (PNG / JPEG / WebP).
Image collage — grid / horizontal / vertical layout
Combine multiple images into one — as a grid, a horizontal strip, or a vertical strip. Composited via Canvas entirely in the browser. Tune columns, gap, padding, background color and output format (PNG / JPEG / WebP). Reorder with up/down buttons.
Convert AVIF photos to JPG / PNG / WebP — compatible everywhere
Decode .avif images with the browser-native AVIF decoder and re-encode them as JPEG / PNG / WebP. AVIF is great for the web but older Safari versions, email clients, Slack and Office still can't preview it — convert before sending. Batch conversion with single-click ZIP download is supported. Files never leave your device — everything runs in the browser.
Color Blindness Simulator
Simulate how an image looks under protanopia (red-blind), deuteranopia (green-blind), tritanopia (blue-blind), or achromatopsia. Check whether your design or chart is color-accessible. Runs in the browser with Canvas and transform matrices — your image is never uploaded.
