*AI processing may take a few seconds depending on your device's performance.

Or try with a sample image

A free tool that utilizes the latest AI (Artificial Intelligence) to automatically detect subjects and remove backgrounds directly in your browser. Unlike typical cloud-based tools, no image uploads to external servers are required, allowing you to use it safely and unlimitedly with no restrictions on the number of images or resolution.

✨ Features of this Tool

Two AI Models for Different Needs

While many tools use a single fixed AI, this tool allows you to freely switch between "U2-Net (Lightweight)" for quick processing and "IS-Net (High Precision)" for cleanly extracting complex outlines like hair.

Freely Adjust Edge Boundaries

Solves common issues with fully automatic tools, such as "I want to erase a bit more" or "It erased necessary parts." Simply move the "Threshold" slider to fine-tune the AI's cutout results in real-time.

Safe with 100% Local Processing

Utilizes the latest web technologies (WebAssembly / ONNX) to complete all AI processing entirely on your device. Your image data is never sent to or stored on external servers.

Pro-level Verification Features

Change the background color to "Green (Chroma Key)" or "Magenta." This allows you to strictly check for tiny leftover edges that are hard to notice on a checkerboard pattern before saving.

Detailed Explanation of Settings

Model

How to Choose the AI Model

[U2-Net (Lightweight)]: Fast processing, sufficient for general photo cutouts. Recommended for quick workflows.
[IS-Net (High Precision)]: Specialized for high-precision cutouts. Try this for animal fur, human hair, or complex objects. *Note: Processing takes slightly longer.

Threshold

How to Adjust Edge Boundaries

Sets the standard (threshold) for what becomes transparent based on the AI's probability data.
- Increase (Move Right): Increases transparent areas. Effective when background colors remain on the edges.
- Decrease (Move Left): Decreases transparent areas. Effective when necessary parts of the subject are accidentally erased.

Step-by-Step Guide

  1. Load an Image
    Drag and drop an image into the dotted area or click to select a file.
  2. Select an AI Model (Optional)
    Choose "U2-Net (Lightweight)" or "IS-Net (High Precision)" based on your needs.
  3. Run AI Processing
    Click the "Remove Background" button, and the AI will automatically cut out the subject. *Note: The first run takes time to download the AI weight data (several to tens of MB).
  4. Fine-tune the Results (Optional)
    Change the "Background Color" to green to check the outlines, and move the "Threshold" slider to adjust the boundaries if necessary. Changes reflect instantly in the preview (no need to re-run AI).
  5. Download the Image
    Click the "Download" button to save the image with a transparent background (PNG format).

Recommended Use Cases

E-commerce & Marketplaces

Remove lifestyle backgrounds from product photos with one click to create clean white backgrounds or composite materials.

YouTube & SNS Images

Cleanly cut out people, VTuber avatars, or items to create impactful thumbnails and eye-catches.

Presentations & Proposals

Perfect for making white backgrounds of company logos or product images transparent so they blend beautifully into slide backgrounds.

Frequently Asked Questions (FAQ)

The "Preparing..." screen doesn't progress.
On the first use or right after switching AI models, it downloads the AI data (about 4MB - 45MB) to your browser, which may take tens of seconds depending on your network connection. From the second time onward, it is cached and processes quickly.
The background becomes white after saving.
When resaving in other image editing software, ensure you aren't saving it in "JPG (JPEG) format". The JPG format does not support transparency, so transparent parts will be filled with white. Always use "PNG format" to keep the background transparent.
Can I use it on smartphones or tablets?
Yes, you can access and operate it directly from standard browsers like Safari or Chrome. However, since it uses your device's performance (CPU/Memory) instead of a server, older smartphones might take longer to process or cause the browser to freeze.
