How to remove an image background
Three simple steps — all on your device.
- 1
Upload your image
Drop in a JPG, PNG or WebP. The AI model runs in your browser — nothing is uploaded.
- 2
Let the AI cut it out
An on-device model separates the subject from the background in a few seconds. The model downloads once, then is cached.

On-device AI
A machine-learning model runs entirely in your browser via WebAssembly — no server, no upload, no account.

Export a transparent PNG, or composite the cutout onto any background colour.
Free, no signup, no watermark

Remove backgrounds without uploading your photos
Most background removers send your image to a server. PDF for Joy runs the AI model on your device, so your photos — including people and personal pictures — never leave your browser. It even works offline once the model is cached.
It works best on clear subjects like people and products. Download a transparent PNG for logos, thumbnails, product shots and profile pictures, or add a solid background colour in one click. Free, with no watermark.
Private by design. Every file stays on your device — nothing is uploaded to or stored on our servers.
Frequently asked questions
How does it remove the background without uploading my image?
A small AI model runs directly in your browser using WebAssembly. Only the model is downloaded (once, then cached) — your image itself is never uploaded.
Does it work on my phone — Android or iPhone?
Yes. It runs in your mobile browser on both Android and iPhone, with no app to install. Open the tool, pick a photo from your camera roll, and download the cutout. Because the AI runs on your device, your image never leaves your phone.
What images work best?
Photos with a clear subject — people, products, or objects on a reasonably distinct background — give the cleanest cutouts.
Can I add a coloured background?
Yes. After removing the background you can download a transparent PNG or pick a solid colour to composite behind the subject.
Are my files uploaded to a server?
No. Every conversion and edit happens inside your own browser using your device's processing power. Your files never leave your computer or phone, which makes this safe for IDs, bank statements, contracts and other private documents.
Is it really free?
Yes. The core tools are completely free with no signup, no watermark and no daily limits.
