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.
Drop your photo
Drag an image onto the page or click to browse. It opens in the GhostImage studio with Remove background pre-selected.
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.
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.
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.
Every GhostImage tool runs entirely in your browser. Your file is never uploaded — there's no upload endpoint to send it to.
