How this service works

Cut a region out of an image (left, top, width, height), or, without left and top, crop it to the given size around its most interesting region (libvips attention strategy).

Output

Returns a JSON object containing a temporary CDN URL to the cropped image (valid for 1 hour), the output dimensions (width, height), file size in bytes, and the output format. Optionally includes the image as a base64 data URL if it is 1 MB or smaller and the inline flag is set.

Example use cases

Smart crop product photo for e-commerce

“Take this product image at https://shop.example.com/shoe.png and smart-crop it to 800×800 pixels so it centers on the shoe itself — output it as a WebP.”

Extract specific region from screenshot

“I need you to cut out the chart area from this dashboard screenshot at https://cdn.example.com/dashboard.png — it starts at left 120, top 80 and is 640 pixels wide by 400 pixels tall. Save it as a PNG.”

Auto-crop portrait photo for avatar

“Smart-crop this portrait photo at https://photos.example.com/person.jpg to 400×400 pixels centered on the most interesting part of the image, and give me it back as a JPEG.”

Technical details

Endpoint

POSThttps://image.kagurazaka.dev/v1/crop?utm_source=zero.xyz

When to prefer

Use this endpoint when you need to extract a specific rectangular region from an image by pixel coordinates, or when you want automatic subject-aware cropping using libvips attention strategy without needing to know where the subject is. Prefer it over generic resize endpoints when the goal is to reduce the frame of the image rather than scale it down, and over thumbnail endpoints when you need precise coordinate control or non-square output dimensions.

Side effects

Image URL unreachable or returns non-2xx — 4xx/5xx error response
Image exceeds 20 MB or 40 megapixels limit — rejected with size error
Unsupported image format (e.g. BMP, HEIC) — format error
Crop coordinates out of bounds for the image dimensions — geometry error
left/top provided without width/height or vice versa — parameter validation error
Network timeout fetching remote image — timeout error
