How to do it
JPG files cannot store transparency, so the result is saved as a PNG. Choose your JPG, remove the background and download.
Tip: If you need a JPG again later, choose "White" or a custom colour instead of transparent.
How it works
- Choose, drop or paste one or more images.
- Pick a mode. "Photo (AI)" runs a segmentation model on your device; the first run downloads it once (about 44 MB). "Signature, logo or stamp" removes a plain background colour instantly, with no download.
- Choose transparent, white or any colour, and the size. You can change these afterwards without re-running.
- Download PNG (transparent) or JPG (solid background).
Which mode should I use?
| Your image | Best mode | Why |
|---|---|---|
| Person, pet, product photo | Photo (AI) | Separates a subject from a complex background |
| Signature or handwriting on paper | Signature, logo or stamp | Keeps thin pen strokes that AI models can miss |
| Logo or clipart on a solid colour | Signature, logo or stamp | Exact colour removal, sharp edges |
| Line art, manga, black-and-white drawings | Signature, logo or stamp | Keeps every line |
| Object on a busy or patterned background | Photo (AI) | Colour removal needs a plain background |
Honest limits
- Fine hair, fur, glass and smoke can leave soft or missing edges.
- Objects that are the same colour as the background are hard to separate.
- Images larger than 4,000 pixels on the longest side are scaled down.
- iPhone HEIC photos must be converted to JPG first in most browsers.
Your images stay private
Most free background removers upload your photo to a server. CutRuler runs the model in your browser, so your images never leave your device. That matters for signatures, ID photos and unreleased products.

Frequently asked questions
Why did my file become a PNG?
The JPG format has no transparency. PNG keeps the transparent areas.
Is CutRuler free?
Yes. There is no sign-up, no watermark and no image limit, because processing runs on your device.
Are my images uploaded?
No. They are processed in your browser. Only the model files and code library are downloaded.
Why is the first AI run slower?
The model downloads once (about 44 MB) and is then cached by your browser.
