## Frequently Asked Questions

### What is RMBG?

RMBG is a free, browser‑based tool that removes backgrounds from images directly on your device. The app downloads a ~98 MB model and inference runtime from third‑party CDNs, caches them in your browser, and then processes photos locally, so no image bytes are ever uploaded to a server. It supports PNG, JPG, WebP, AVIF, BMP and GIF (first frame) as inputs and can export cutouts as PNG, WebP, JPEG or AVIF where supported. Users can refine results with brushes, guided clicks, or drag‑a‑box re‑computations, and all edits are undoable. Up to 24 images can be queued for sequential processing, and exports can be downloaded as a single ZIP. The tool runs fastest with WebGPU, falling back to CPU if needed, and displays which backend is in use. No account, credits, or watermarks are required, and the MIT‑licensed software includes settings for format selection, background choice for JPEGs, and mask feathering. Limitations include an initial model download, slower performance on CPU‑only devices, and lack of HEIC support. GateOnAI Score: 67/100.

### What is Nano Banana 2.1 Pro?

Nano Banana 2.1 is an AI image generator and editor that creates and modifies pictures from text prompts and reference images. Users write a prompt, upload up to 14 reference photos, and select one of four models—Nano Banana 2.1, 2, Pro, or Lite—while viewing the credit cost before each request. The tool supports square, portrait, and landscape compositions, with resolutions up to 4K depending on the chosen model, and it can embed exact quoted text such as headlines or labels directly into the image for proof‑reading before publishing. The workflow guides users through describing the idea, adding references, choosing model and aspect ratio, and reviewing the output beside the prompt. It highlights features like preserving faces, products, and specific details, and offers illustrative examples without consuming credits. Nano Banana 2.1 is suited for creators who need precise control over visual elements and text integration in generated images. GateOnAI Score: 67/100.
