AI background removal that stays on your device

Removing a background by hand takes ages. This tool uses the open-source U²-Net deep-learning model to find the main subject of your photo and cut it out in a couple of seconds. Unlike most online removers, the model runs inside your browser — your photo is never uploaded to anyone's server.

Download the cut-out as a transparent PNG for design work, or give it a clean white background for marketplaces, a brand colour, or a soft blurred version of the original for a portrait-style look. A before/after slider lets you check the edges.

How to remove a background

  1. 1

    Choose a photo

    Pick an image with a clear main subject. The first time, the AI model (about 4.6 MB) downloads once.

  2. 2

    Let the AI work

    The subject is detected and the background removed automatically.

  3. 3

    Pick a new background

    None (transparent), white, any colour, or blurred. Toggle crisp or soft edges.

  4. 4

    Download

    Save a transparent PNG, or a PNG/JPG with the new background, at full resolution.

Key features

  • Automatic cut-out

    No brushes or manual selection needed.

  • Truly private

    The AI runs on your device — ideal for personal photos and unreleased products.

  • New backgrounds

    Transparent, white, custom colour or blurred original.

  • Full resolution

    The mask is applied to your original photo, not a small preview.

Common uses

  • Product photos: White-background images for Amazon, Flipkart, Meesho or your own shop.
  • Profile and ID pictures: Swap a messy room for a plain background.
  • Design and presentations: Drop cut-outs onto slides, posters and thumbnails.

Tips and good to know

  • Best results come from photos where the subject is in focus and stands out from the background.
  • Fine hair and fur are the hardest part for any AI; switch off Crisp edges for a softer, more natural outline.
  • For online passport photos, check the official rules — many require a plain white or light background and a specific size. Resize afterwards with the Image Resizer.
  • Want the subject on a branded thumbnail? Try the Thumbnail Generator.

Frequently asked questions

Is this background remover really free?

Yes. There are no credits, watermarks or sign-ups, and you download the full-resolution result.

Are my photos uploaded to a server?

No. The AI model is downloaded to your browser and runs there, so your photo never leaves your device.

Why does the first run take longer?

Your browser downloads the 4.6 MB AI model the first time. After that it's cached and removal takes a second or two.

What kinds of images work best?

People, products, animals and vehicles with a clear outline. Busy scenes with no obvious main subject are harder.

Can I get a white background instead of transparent?

Yes. Choose White (or any colour) under New background, then download as JPG or PNG.
