## Tools in detail

### Transparent background maker (https://nukebg.com/transparent-background-maker)
Upload a photo and NukeBG removes the background, leaving your subject on a real transparent layer. Download a PNG or WebP with a true alpha channel that drops cleanly onto any colour, slide or design.

How it works:
1. Upload: Drop a JPG, PNG or WebP up to 25 MB, or paste an image link.
2. We cut it out: The AI finds the subject and removes everything behind it, cleaning colour spill from the edges.
3. Download: Save a transparent PNG or WebP, or place it on white, a colour or a scene.

Highlights:
- True alpha, not a fake checkerboard: The file has a real transparency channel, so it works in Canva, Figma, PowerPoint, Photoshop and on the web.
- Clean edges: Hair, fur and soft edges keep their detail, and background colour bleeding into the edges is removed.
- PNG or WebP: PNG for maximum compatibility, WebP for smaller files on websites.
- Free to start: 50 free credits when you sign up, plus 20 every month. One standard cutout is one credit, with no watermark.

Q&A:
Q: How do I make the background of an image transparent?
A: Upload the image to NukeBG. The background is removed automatically and you can download the result as a transparent PNG or WebP.

Q: Is the transparent PNG really transparent?
A: Yes. NukeBG exports a real alpha channel. The checkerboard you see in the editor is only a preview of the transparent area, not part of the image.

Q: Is it free?
A: You get 50 free credits at sign-up and 20 more each month. A standard cutout costs one credit, and free results never have a watermark. Free accounts export up to 2 megapixels.

Q: Which file formats can I upload?
A: JPG, PNG and WebP images up to 25 MB.

### White background remover (https://nukebg.com/remove-white-background)
White and light-grey backgrounds are the hardest to cut cleanly because they blend into bright products and paper-white logos. NukeBG separates the subject from the white behind it and gives you a transparent image with crisp, spill-free edges.

How it works:
1. Upload your image: Photos, scans, screenshots and logos on white all work.
2. White is removed: The subject is kept and everything white around it becomes transparent.
3. Export: Download a transparent PNG, or put it on a new colour, gradient or scene.

Highlights:
- Works on white products: Bright and white products against white backdrops keep their outline instead of fading into the background.
- Keeps inner details: Text, labels and logos on the product are never redrawn. Only the background is removed.
- Or go the other way: Need a pure white background for Amazon or eBay? Choose white and a marketplace size in one step.
- Batch it: Upload up to 100 images at once in the Studio, or send them through the API.

Q&A:
Q: How do I remove a white background from an image?
A: Upload it to NukeBG. The white background is detected and removed automatically, and you can download a transparent PNG.

Q: Can I remove the white background from a logo?
A: Yes. Upload the logo and download it as a transparent PNG, ready to place on any colour. See the logo background remover for tips.

Q: Can I add a pure white background instead?
A: Yes. Choose a white background and, for marketplaces, the Amazon (2000×2000, pure white) or eBay preset.

Q: Does it work on white products?
A: Yes. The cutout separates the product from the background by shape, not just colour, so white items on white keep their edges.

### Video background remover (https://nukebg.com/video-background-remover)
Upload a clip and NukeBG removes the background from every frame, no green screen needed. Download a video with a transparent background for your editor, or a green-screen MP4 that works everywhere. The original audio is kept.

How it works:
1. Upload a clip: Up to 60 seconds and 1080p, MP4, MOV or WebM.
2. Every frame is cut out: The subject is separated frame by frame on GPUs, with smoothing so edges don't flicker.
3. Choose your format: Transparent WebM, ProRes 4444 MOV with alpha, or a green-screen MP4.

Highlights:
- Real transparency: WebM (VP9 with alpha) and ProRes 4444 MOV keep a true alpha channel for Premiere, Final Cut, DaVinci Resolve and After Effects.
- Green screen when you need it: Export an MP4 on a solid green background for apps that can't read alpha.
- Audio kept: The original soundtrack is copied into the result unchanged.
- Fair per-second pricing: 5 credits per second of video, charged only for what is processed. Failed jobs are free.

Q&A:
Q: How do I remove the background from a video?
A: Upload the clip in the NukeBG Studio's video tool, pick a format and start. You get a download link when it's done, and an email if you've left the page.

Q: Can I get a transparent background video?
A: Yes. Choose WebM (VP9 with alpha) or ProRes 4444 MOV for a real transparent background, or MP4 on green screen.

Q: How long can the video be?
A: Up to 60 seconds and 1080p per clip.

Q: How much does it cost?
A: 5 credits per second of video, using paid credits. A 10-second clip is 50 credits. Failed jobs are never charged.

### AI image upscaler (https://nukebg.com/upscale-image)
Turn small or soft photos into larger, sharper images. NukeBG's AI upscaler adds real detail instead of just stretching pixels, so product photos stay crisp when marketplaces zoom in and prints stay sharp.

How it works:
1. Upload: JPG, PNG or WebP. Up to 16 MP for 2×, up to 4 MP for 4×.
2. Pick 2× or 4×: 2× doubles the width and height; 4× makes it four times larger in each direction.
3. Download: Get a PNG, WebP or JPG at the new size.

Highlights:
- AI detail, not blur: Real-ESRGAN reconstructs edges and texture so enlarged images look sharp instead of soft.
- Made for products: Hit marketplace minimums and enable zoom on product pages without reshooting.
- Works with cutouts: Upscale a cutout, then place it on white or a scene at any marketplace size.
- Simple pricing: 2× costs 2 credits and 4× costs 4 credits, using paid credits. Packs start at $15 and credits never expire.

Q&A:
Q: How do I upscale an image?
A: Open the upscale tool in the NukeBG Studio, upload your image, choose 2× or 4× and download the larger version.

Q: What's the difference between 2× and 4×?
A: 2× doubles the width and height (4× the pixels). 4× makes the image four times wider and taller (16× the pixels).

Q: Is upscaling free?
A: Upscaling uses paid credits: 2 credits for 2× and 4 for 4×. Your 50 free sign-up credits cover background removal and object removal.

Q: Can I upscale in bulk?
A: Yes. Use the API's upscale endpoint or a batch of up to 500 images.

### Object remover (https://nukebg.com/remove-object-from-photo)
Remove people, wires, stains, props and clutter from photos. Paint over what you don't want and AI fills the area so it looks like it was never there. Everything outside your brush keeps its original pixels.

How it works:
1. Upload a photo: JPG, PNG or WebP.
2. Brush the object: Paint over what should disappear. Or describe it, like "remove the cables".
3. Download: Only the brushed area changes; the rest of the photo is exactly as shot.

Highlights:
- Only what you brush changes: AI results are pasted back only inside your brush, so products, faces and text elsewhere are never altered.
- Fast or Enhanced: Fast mode for everyday clean-ups; Enhanced for tricky textures and large areas (paid credits).
- Describe it instead: For obvious objects you can type what to remove instead of brushing.
- Never charged for refusals: If the AI declines or removes nothing, you aren't charged.

Q&A:
Q: How do I remove an object from a photo?
A: Open the remove-objects tool in the NukeBG Studio, brush over the object and apply. You'll get the cleaned photo in seconds.

Q: Will it change the rest of my photo?
A: No. Only the area you brush is replaced. Everything else keeps its original pixels.

Q: How much does it cost?
A: Fast removal costs 25 credits and is covered by free credits. Enhanced costs 40 paid credits.

Q: Does it work on large areas?
A: Yes. For large areas or detailed textures such as grass, fabric or patterned walls, Enhanced mode gives the most natural fill.

### Background removal API (https://nukebg.com/remove-background-api)
One HTTP call returns a transparent PNG, a white-background JPG or a marketplace-sized image. Credits are only charged on success, retries are safe with idempotency keys, and the /v1.0/removebg endpoint accepts remove.bg requests unchanged.

How it works:
1. Create a key: Sign up, open your account and create an API key. You start with 50 free credits.
2. Send an image: POST to https://api.nukebg.com/v1/cutouts with a file, URL or base64.
3. Get the result: Receive image bytes or JSON, with headers for credits used, size and subject box.

Highlights:
- remove.bg compatible: POST /v1.0/removebg accepts the same parameters and returns the same headers and error format. Change the URL and key.
- Batches, jobs and webhooks: Send up to 500 images in a batch, poll or receive signed webhooks, and download results as a ZIP.
- Safe retries: Send an Idempotency-Key and a successful request is never charged twice.
- Every tool, one API: Cutouts, AI backgrounds, object removal, upscaling and video share one key and one credit balance.

Q&A:
Q: Is there a free background removal API?
A: Yes. New accounts get 50 free credits plus 20 a month, and each standard cutout is 1 credit. Paid packs start at $15 for 4,000 credits that never expire.

Q: Is it compatible with remove.bg?
A: Yes. POST https://api.nukebg.com/v1.0/removebg takes remove.bg parameters such as size, bg_color, crop and channels, and returns the same headers and error shape.

Q: What does a failed call cost?
A: Nothing. Credits are held while a request runs and released if it fails.

Q: What are the rate limits?
A: 20 requests a minute on free credits and 120 a minute with paid credits.
