Review of the web application 'Remove-bg' that can remove the background of images at explosive speed
A web app called ' Remove-bg ' has been released that can quickly remove the background of an image and make it transparent. It claims to be able to perform extremely fast background removal locally, so I tried it out.

Remove-bg can be accessed from the link above. It has been confirmed to work in Chrome on Windows. It did not work in FireFox.
Let's try removing the background from the image below.
Drag and drop the image into the area marked 'Choose file or drag here' on the Remove-bg screen.
The background removal process will be completed in a few seconds. Click 'Download' to download the image in PNG format after the background has been removed.
Here's what the image looks like in Photoshop after the background has been removed. There's still part of the desk in the bottom right of the soft serve ice cream, but the rest of the image is cut out pretty cleanly.
The background removal process is performed using the local GPU, not the server. When I checked the Task Manager, I saw that the GPU was running at 100% only during the removal process. I used the CPU's built-in GPU, and the removal process was completed in just a few seconds.
Remove-bg can also process entire folders. To test this, we prepared a folder containing multiple images.
Drag and drop the folder into the area marked 'Choose directory or drag here.'
The images will be processed one after another. Once the processing is complete, click 'Download as zip'.
The processed images were downloaded in bulk in ZIP format.
When I extracted the ZIP file, the image after background removal was saved. After background removal, the image is saved in PNG format, but the file extension is retained. Therefore, if the original image was in JPEG format, a file with a .jpg extension will be generated even though the file format is PNG. The extension can be manually corrected.
Let's check the processing results. First, here is the original image.
The processed image is below. The camera and film are clearly visible.

The spoon disappeared halfway through.
I'll try it with illustrations too.
Some of the hair at the back has disappeared, but it looks good overall.
However, when I tried placing a pure white layer as the background, a shadow remained in the upper right corner. While you can easily remove the background using Remove-bg, it is often necessary to manually correct the problem because it is impossible to specify a foreground or the desired part does not remain.
Also, if you access Remove-bg again or refresh the screen, it may consume a lot of memory and cause the tab to crash. In that case, you can clear your history and cache and then access it again to make it usable.
The background removal process of Remove-bg uses the background removal AI model ' RMBG v1.4 .' The source code for Remove-bg is available at the following link.
