GhostImageStudio

Remove the background, on-device.

An AI model runs in your browser — the photo never leaves your device, and full resolution is free.

Remove the background from a photo with on-device AI — free, full resolution, and completely private. GhostImage runs a segmentation model in your browser via ONNX Runtime (WebAssembly): the model downloads once (~40 MB), is cached for next time, and your photo itself never leaves your device. Choose the finish — a transparent PNG cutout, a solid background color, a blurred background, or a sticker-style outline with a drop shadow. No per-image caps and no paywalled resolution, because there's no server doing the work.

How it works

  1. 1

    Drop your photo

    Drag an image onto the page or click to browse. It opens in the GhostImage studio with Remove background pre-selected.

  2. 2

    The AI runs on your device

    First use downloads the segmentation model (cached afterwards), then it separates the subject from the background locally — nothing is uploaded.

  3. 3

    Pick a finish and download

    Keep it transparent (PNG), fill with a solid color (JPG), blur the original background, or add a sticker outline — then save.

Frequently asked questions

  • How do I remove an image background for free without uploading the photo?

    GhostImage ships the AI to you instead of shipping your photo to a server: an on-device segmentation model runs in your browser through ONNX Runtime WebAssembly. The photo never leaves your machine, and full resolution is free.

  • Why is the first run slow?

    The model (~40 MB) has to download once. It's cached by your browser, so later images skip the download and go straight to inference.

  • What output do I get?

    A PNG with real transparency by default. Choosing a solid background color produces a JPG; blur keeps your original background but defocused; sticker adds a white outline and drop shadow.

  • How does it compare to remove.bg?

    Cloud services often paywall full-resolution results and require uploading your photo. GhostImage is free at full resolution and never sees the image — the trade-off is that very fine detail (stray hairs, complex glass) may be handled better by specialized paid models.

  • Can I put the cutout on a new background?

    You can fill any solid color directly. For a picture background, download the transparent PNG and layer it in any editor — or keep stacking studio steps like crop and resize first.
