📸Screenshots & Previews
Generate Website Thumbnails via API
Thumbnails. The internet loves them. Every directory site, every bookmark manager, every "top sites" grid needs them. denkbot.dog generates real browser screenshots and returns them as PNG. No PhantomJS relics, no canvas tricks. Just Chromium and a POST request.
What you'd use this for
Website directory thumbnails, browser new-tab pages, bookmark managers, link aggregators, and any product that visually represents websites.
How it works
example
# Generate a thumbnail at 320×240
curl -X POST https://api.denkbot.dog/screenshot \
-H "Authorization: Bearer YOUR_API_KEY" \
-H "Content-Type: application/json" \
-d '{
"url": "https://example.com",
"width": 1280,
"height": 800,
"fullPage": false
}' \
--output thumb.pngQuestions & Answers
What size is the output PNG?+
Depends on the page content. For a 1280×800 viewport, typically 200-800KB.
Can I resize after capture?+
Not via the API. You'd resize in your own image processing pipeline after receiving the PNG.
What about retina/HiDPI?+
Not currently. Screenshots are 1x pixel density.
