ZeroBG uses advanced AI technology (BiRefNet) to automatically detect and remove backgrounds from images. Simply upload your image, and our AI will process it in seconds, delivering a professional-quality result with a transparent background.

No. You can try ZeroBG without signing up and download a free preview (up to 512px, with a zerobg.ai watermark; limited per day). One full-resolution photo is $1.99 with no account. A free account includes 1 HD credit — each credit unlocks the watermark-free download of one image.

We support all common image formats including PNG, JPG, JPEG, and WebP. The processed images are delivered in PNG format with transparent backgrounds.

Processing an image and downloading the watermarked preview is free (with a daily limit). A credit is spent only when you unlock the full-resolution, watermark-free HD download of an image — one credit per image, and unlocking the same image again never costs extra. New accounts get 1 credit. One photo is $1.99 with no account. Need more? Buy a one-time pack — 20 HD credits for $4.99 or 100 for $9 — or subscribe: Basic (100 credits/month), Pro (300 credits/month) or Business (1,200 credits/month). The same credits work for batch and the API.

One-time packs with no subscription: 20 HD credits for $4.99, or 100 for $9. Each credit unlocks one full-resolution, watermark-free image. Pack credits never expire, even if you subscribe or cancel later, and anyone can buy them. A credit pack also unlocks batch processing (10 images) and the API.

Subscription credits don't roll over: each month they reset to your plan's monthly amount (yearly plans too, once a month). Sign-up credits and one-time pack credits never expire and stay in your balance if you subscribe or cancel. When you unlock an HD image, subscription credits are used first.

Absolutely! You can cancel your subscription at any time and keep your plan until the end of the period you've paid for. After that, unused subscription credits expire; sign-up and credit-pack credits stay in your account.

Free previews are resized to 512px on the longest side and carry a zerobg.ai watermark. Unlocked HD downloads keep the original resolution of your upload, with no watermark and no quality loss.

Yes, the maximum file size for uploads is 25MB. This covers most high-resolution images while ensuring fast processing times.

We store your images only so you can preview and download them. Without an account, uploaded and processed images are automatically deleted after 24 hours. With an account, they are kept for your plan's history period (Free: 30 days, Basic: 90 days, Pro: 180 days, Business: permanent) and then automatically deleted. See our Privacy Policy for details.
