Background Remover
Drop in an image and Spark Tray cuts the subject out for you, handing back a clean transparent PNG. Do one or a whole batch, preview the result, and swap in a solid colour or a fresh background if you'd rather not leave it transparent.

Cutouts save to your Cutouts folder as transparent PNGs.
What it does
Everything Background Remover handles
A focused set of jobs, each done well — and nothing that phones home.
Clean transparent PNGs
The subject is separated from its background and saved as a PNG with real transparency, ready to drop anywhere.
Single or batch
Cut out one image or hand Spark Tray a whole folder's worth and let it work through them in one go.
Replace the background
Prefer a backdrop to transparency? Drop in a solid colour or another image and Spark Tray composites it behind the subject.
Live preview
See the cutout before you save, so you know exactly what you're getting instead of guessing.
Runs on your CPU
The ISNet model runs locally on your processor — no graphics card required and nothing sent to a server.
Straight to Cutouts
Finished images save to your Cutouts folder, named to match their source so they're easy to find.
How it works
From link to done in a few clicks
- 1
Drop in an image

The @imgly ISNet model separates foreground from background right on your CPU — no upload, no wait for a queue.

Leave the background transparent, or swap in a solid colour or a new image and preview the result.

Save your cutouts
Export to your Cutouts folder as transparent PNGs, ready for design tools, docs or the web.
Under the hood
The engines, named plainly
The background remover does its thinking entirely on your machine.
- Model
- @imgly background removal — ISNet

- Output
- Transparent PNG
- Modes
- Single or batch, with optional solid-colour or image background replacement
- Output folder

- Windows 10/11 (x64) — runs fully on your machine
Because the ISNet model runs locally through the ONNX runtime, your images never leave your computer — there's no upload step and no account. The first run downloads the model on demand, then works offline.
