One-click image masking

What is one-click image masking?

One-Click Image Extraction is an online AI-based image extraction and comprehensive image processing platform developed by Shanghai Lijie Information Technology.

After a user uploads an image, the subject and background can be automatically separated, allowing the user to change the background, edit the image, compress it, or convert it to another format.

Core functions

Portrait masking

Portrait masking automatically detects the edges of the subject and separates them from the background.

• Ideal for ID photos, profile pictures, posters, and social media images.
• It can output a transparent background, or it is possible to replace it with a solid color, a template, or a custom image.
• It performs intelligent recognition of hair strands, folds in clothing, and details of contours.
• When the automatic results are not satisfactory, the edges can be manually removed to make corrections.
• When the background and the colors of the characters are similar, it is necessary to zoom in to check for missed areas that need to be included and for any jagged edges.

Removing objects and items from images

Object extraction is suitable for non-portrait subjects such as products, animals and plants, graphics, and everyday items.

• E-commerce users can quickly create images with a white background or scene display images.
• Stores and social media platforms can include products in posters or promotional materials.
• Natural results are usually easier to achieve when the edges of the subject are clear and the background is simple.
• Transparent, reflective, fuzzy, and hollow objects may still require manual edge trimming.
• The color and details of the product must not be presented in a misleading manner as a result of processing.

Change background and create smart ID photos

After the image extraction is complete, the transparent background can be retained, or it can be replaced with another color.

• A transparent background is suitable for subsequent formatting, design, and combining product images.
• A solid-color background can be used for ID photos and standardized document images.
• Background templates are suitable for quickly creating posters or everyday scenes.
• Custom backgrounds can be created by uploading local images for creative compositing.
• The requirements regarding the size of ID photos and the background color should be in accordance with those set by the issuing authority.

Image editing tools

In addition to image masking, the platform also offers a set of common online image editing functions.

• Comprehensive editing: cropping, filters, parameter adjustment, borders, stickers, and text.
• Resize image: Supports zooming in, zooming out, or entering the target pixel size.
• Image cropping: Common sizes are available, and it is also possible to define custom cropping ranges.
• Adjust resolution: DPI values such as 72, 96, 150, and 300 can be set.
• Add watermarks to images: Supports text or image watermarks, and allows adjustment of their position and transparency.
• Image rotation: Quickly change the orientation of the image to correct the shooting angle.

Image compression and format conversion

One-click image extraction supports common image compression, format conversion, and conversion of images to PDF.

• Compressible formats such as JPG, PNG, BMP, GIF, and JPEG.
• Supports conversion between JPG, PNG, BMP, WEBP, GIF, and ICON.
• Converting HEIC to JPG is suitable for processing photos taken with Apple devices.
• When converting images to PDF, it is possible to set the paper size, orientation, margins, and the method of merging pages.
• The batch processing entry point and the available quantity may vary depending on the website or client.

Tutorial for using one-click image extraction

1. Go to the official website for one-click image masking, and select either portrait masking or object masking.
2. Upload JPG, PNG, or other image formats supported by the page.
3. Wait for the system to automatically identify the subject and remove the original background.
4. Switch between the original image and the resulting image, and zoom in to examine the hair strands, edges, and hollow areas.
5. Use manual removal or retention tools as needed to adjust the selection range.
6. Choose a transparent background, a solid-color background, a template, or a local image as the new background.
7. Adjust the canvas size, DPI, cropping area, and export format according to the intended use.
8. Before downloading, check the image quality, file size, licensing, and the requirements for submission.

How to improve the quality of image masking

• Give priority to uploading original images with clear subjects and sufficient resolution.
• There should be a clear difference in color and contrast between the characters or products and the background.
• Avoid severe motion blur, strong backlighting, and overly compressed images.
• Complex hair patterns, transparent materials, and reflective edges need to be manually refined.
• After changing the background, adjust the light direction, color temperature, perspective, and shadows.
• High-resolution source files should be retained for e-commerce or printing purposes.

Supported platforms

• Web version: It allows for direct image cropping, compression, conversion, and basic editing.
• Windows client: The official website provides a download link for the desktop version.
• Mac client: The official website’s navigation provides the corresponding download link.
• Mobile version: The official website provides a QR code for the app as well as a download link for Android.
• There are many apps with the same name; when installing, it is necessary to verify the official website link and the entity responsible for its development.

The web version is suitable for temporary processing; for batch or more advanced functions, a client application may be required.

Prices and memberships

As of August 30, 2026, the official website does not provide a unified membership package and price list that can be verified in its entirety.

The number of free uses, member benefits, automatic renewal options, and promotional prices may change; the terms that apply are those stated on the settlement page and in the current agreement.

File privacy and security

Multiple upload pages on the official website state that the files uploaded by users will be automatically deleted after 1 hour.

• The automatic deletion prompt does not mean that the image is processed only on the local device.
• ID cards, contracts, customer information, and unreleased product images should still be uploaded with caution.
• Permission to record, edit, and publish someone’s portrait must be obtained before handling it.
• After downloading the result, check whether metadata or sensitive background details have been retained.
• For highly sensitive projects, offline tools or approved corporate solutions should be used preferentially.

API, SDK, and open-source status

Usage restrictions and precautions

• Automatic object removal may produce errors in hair, transparent elements, and edges with similar colors.
• AI restoration relies on speculation regarding details, and therefore cannot be used as a basis for identity, records, or historical facts.
• Changing the DPI does not add real image details out of thin air.
• The file size, number of files, and export restrictions for web tools are determined by the live page.
• When using images of people, brands, artistic works, and products, it is necessary to verify the authorization.
• The final output should be checked at the target device size or print size before official release.
