How can I remove background from a photo or picture in bulk?

DeBG is a completely free and open-source Windows desktop app that remove background from photos entirely on your own computer. You don't upload your images anywhere, which means your privacy stays intact. No cloud, no API keys, no sketchy uploads.

Here's the deal – it runs an AI model locally on your machine, so after the initial setup, you can even use it offline. If you want to remove background from photo free without worrying about your images floating around the internet, this is a great pick.

What Makes It Cool

• Bulk processing: Drop a bunch of images (PNG, JPG, WEBP, BMP) and it processes them all at once
• Multiple AI models: You can pick from 9 different models – from a super tiny 4.7 MB one for speed to a 375 MB high-quality one for the best results
• Live preview: Adjust settings like edge smoothness and see changes instantly without re-processing
• No watermarks or limits: Since it runs locally, there's no "free version with restrictions" nonsense

Here are the step-by-step instructions for using DeBG to remove background from photo free on your Windows PC.

Step 1: Download and Run DeBG

Step 2: Complete the First-Run Setup Wizard

• Choose a Backend: You'll be asked to pick between CPU or GPU (CUDA). If you don't have a high-end NVIDIA graphics card, just select CPU. It works fine.
• Install the AI Model: Click the "Install rembg" button. The wizard will then handle everything for you—it'll check for Python, download it if needed, and set up the AI engine.
• Be Patient: This first-time setup takes about 5 to 10 minutes, so go grab a coffee while it does its thing. After this, you won't have to do it again.

Step 3: Add Your Photos

• Once the setup is complete, you'll see DeBG's main interface. You can drag and drop any number of images (PNG, JPG, WEBP, BMP) directly into the window.

Step 4: Remove the Backgrounds

• In the app, you can choose one of the 9 AI models to use. The larger models give better results but take a bit longer. Then, just click the "Remove backgrounds" button and let it process your batch of photos.

Step 5: Get Your New Images

• After processing, the app automatically saves the transparent PNG results to your chosen output folder. You can also export all results as a single ZIP file with one click.
