AI Image & Video Background Remover APIs - Remove Backgrounds Instantly

Q: How accurate is the edge detection on complex subjects?

The segmentation model produces high-quality alpha mattes for most subjects including hair, fur, and semi-transparent materials. Edge quality depends on contrast between subject and background. The API returns a matte quality score to help evaluate output.

Q: Can I replace the background with a custom image instead of making it transparent?

Yes. Pass a background parameter with a hex color, gradient definition, or URL to a replacement image. The API composites the subject onto the new background with automatic edge blending.

Q: What happens with images that have multiple subjects?

By default the API removes the background from all detected foreground subjects. Use the subject_index parameter to isolate a specific subject. The response includes a subjects_detected count.

Q: How does batch processing work?

The /v1/remove-bg/batch endpoint accepts up to 100 image URLs per request with parallelized processing. Results are returned via webhook or polling. A 100-image batch typically completes in under 60 seconds.

Q: How is background removal priced?

Pricing is per-image based on output resolution. Background replacement is included at no extra cost. Cached results within 24 hours are free. Volume discounts are available.

BACKGROUND REMOVAL API

Remove Backgrounds with a Single API Call

The Pixazo Background Remover API isolates foreground subjects from any image and video using semantic segmentation models. It handles people, products, animals, and complex scenes -- returning a transparent PNG, MP4 or a composited result with your chosen replacement background. Built for automated catalog pipelines, photo and video editing apps, and design tools that need reliable cutouts at scale.

Upload Image or Video Frame

Send a JPEG, PNG, WebP, or video frame via URL or base64. The API detects the primary subject automatically -- no manual selection or mask required.

Segment & Mask

A semantic segmentation model generates a high-resolution alpha matte, preserving fine edges like hair, fur, and semi-transparent materials.

Return Result

Get a transparent PNG or MP4, or specify a solid color or replacement image as the new background. Results are cached for 24 hours.

What the API Actually Does Well

Honest capabilities -- and the edge cases where results may need manual touch-up.

Hair & Fur Edge Detection

The segmentation model handles wispy hair, pet fur, and feathered edges better than simple threshold-based tools — including on video frames. It generates a soft alpha matte that preserves semi-transparent areas. Results are strong on clean backgrounds but can struggle with hair that closely matches the background color.

Multi-Subject Support

The API can isolate multiple subjects in a single image or video frame -- a group photo, a product arrangement, or a scene with several distinct objects. You can request all foreground subjects at once or specify a subject index to extract individual elements.

Background Replacement

Beyond simple removal, the API can composite the subject onto a solid color, gradient, or custom background image in a single request. Color matching and edge blending are applied automatically. Works for both images and video frames.

Batch Processing

The /v1/remove-bg/batch endpoint accepts arrays of up to 100 images or video frames per request. Results are delivered via webhook or polling. Processing is parallelized, so batch jobs complete significantly faster than sequential individual requests.

Common Use Cases

Where teams integrate background removal into their production workflows.

Product Photography

Standardize catalog images to white or branded backgrounds. Process entire SKU libraries — images and video frames — automatically.

Design Tools

Power one-click background removal in photo and video editing apps, Canva-style builders, and social media content creators.

ID & Passport Photos

Replace arbitrary backgrounds with compliant solid colors for official document photos. Output meets standard aspect ratios.

Real Estate

Swap overcast skies for blue, remove clutter from property photos, and composite staging elements into empty rooms.

Video Thumbnails

Extract subjects from video frames for YouTube thumbnails and social media previews with clean cutouts.

Print & Merch

Isolate artwork or logos for placement on merchandise mockups -- t-shirts, mugs, posters -- without manual masking.

Frequently Asked Questions

How accurate is the edge detection on complex subjects?+

The segmentation model produces high-quality alpha mattes for most subjects -- including hair, fur, and semi-transparent materials like veils or glass. Edge quality depends on contrast between subject and background. The API returns a matte_quality score to help you decide whether automated output is sufficient.

Can I replace the background with a custom image instead of making it transparent?+

Yes. Pass a background parameter with either a hex color code, a gradient definition, or a URL to a replacement image. The API composites the extracted subject onto the new background with automatic edge blending and color matching.

What happens with images that have multiple subjects?+

By default the API removes the background from all detected foreground subjects. If you want to isolate a specific subject, pass the subject_index parameter. The API returns a subjects_detected count in the response so you know how many were found.

How does batch processing work?+

The /v1/remove-bg/batch endpoint accepts an array of up to 100 image or video frame URLs per request. Processing is parallelized across the cluster. Results are returned via webhook callback or can be polled from a status endpoint. A 100-image batch typically completes in under 60 seconds.

How is background removal priced?+

Pricing is per-image or per-frame based on output resolution. Standard resolution costs fewer credits than high-resolution output. Background replacement adds no extra cost. Cached results within 24 hours are free. Volume discounts are available on the Pixazo API pricing page.
