Free AI Background Remover
Remove image backgrounds with AI directly in your browser, then refine difficult areas with Keep and Remove tools without uploading your image.
Free and unlimited — no credits or daily limits. AI processing runs locally on your device — no account and no upload required.
Remove an image background with AI
The image is decoded, processed, and saved on this device. It is never sent to an inference server.
Remove image backgrounds with AI
Automatically separate a subject from its background using AI directly in your browser. The model runs locally on your device; image pixels and the resulting mask are not uploaded.
If the first result needs work, use the Keep and Remove brushes to restore missing subject details or clear leftover background areas.
Many online AI image tools use credits or daily quotas. Local File Converter runs the AI model directly in your browser, so there is no per-edit credit system or daily usage cap. Your image stays on your device instead of being uploaded to an AI processing server.
Refine difficult edges
Automatic segmentation can need help around hair, fur, fingers, thin objects, and complex backgrounds. Paint Keep over subject pixels and Remove over background pixels to correct the local alpha mask without starting over.
How to remove an image background
1. Choose an image
Select a JPG, PNG, or WebP image from your device.
2. Remove the background
The AI model analyzes the image locally and creates a transparent mask.
3. Refine if needed
Use Keep and Remove brushes to correct missing details or leftover background.
4. Save your image
Save the result as a transparent PNG at the source dimensions.
Runs locally
The AI model runs on your device. Your image is not uploaded for processing.
Manual refinement
Correct difficult areas with Keep and Remove tools instead of accepting an imperfect result.
Original dimensions
The output mask is mapped back to the source dimensions within device memory limits.
Transparent PNG export
Save the refined result as a transparent PNG at the source dimensions.
Frequently asked questions
Are my images uploaded?
No. The image is decoded, segmented, refined, and exported locally in your browser. The browser only downloads the model required for local inference.
Is the AI tool unlimited?
Yes. There are no credits or daily usage limits. AI processing happens directly in your browser, so you can use the tool as often as your device and browser support.
Can I correct the AI result?
Yes. Use Keep to restore missing subject areas and Remove to clear remaining background. These edits update the local alpha mask without rerunning the model.
Does it work with hair and fur?
MODNet is a lightweight portrait matting model. Results depend on the image; the Keep and Remove brushes are available when the automatic edge needs correction.
Does background removal reduce image resolution?
The model uses an optimized inference size, then maps the alpha mask back to the original image dimensions. The saved PNG keeps the source dimensions within the browser's safe memory limits.
Which file formats are supported?
The tool works with JPG, JPEG, PNG, and WebP images. The final image is saved as a transparent PNG.
What happens if my browser cannot run AI?
The tool explains that local AI is unavailable. It never uploads the image or sends it to a third-party inference service.
