Frequently Asked Questions
How does LeanImg remove backgrounds?
LeanImg uses BiRefNet, a state-of-the-art neural network for image segmentation. When you upload an image, the AI identifies the foreground subject and separates it from the background, producing a transparent PNG. The model handles complex edges like hair, fur, and semi-transparent objects with high accuracy.
What file formats does LeanImg support for background removal?
You can upload JPG, PNG, WebP, AVIF, and GIF images. The output is always a transparent PNG file, which preserves the cutout with full alpha transparency. You can then compress or convert the result using our other free image tools.
Can I remove backgrounds from multiple images at once?
Yes. LeanImg supports batch background removal — select up to 10 images at a time and process them all in one go. Download results individually or all at once as a ZIP file. No sign-up or account required to use batch processing.
Is the background removal really free?
Yes, completely free with no limits. There is no sign-up, no watermarks, and no hidden fees. Unlike competitors that charge per image or cap resolution on free tiers, LeanImg processes full-resolution images at no cost. Use it for product photos, portraits, or any image.
How accurate is the background removal?
LeanImg uses BiRefNet, which achieves state-of-the-art results on dichotomous image segmentation benchmarks. It excels at fine detail like hair strands, transparent objects, and complex edges. Results are comparable to premium paid services like remove.bg and PhotoRoom.
