How this service works

86 APIs for AI agents: web scraping and crawling to Markdown, AI summaries, data extraction and cited answers, screenshots and PDF, PDF, OCR and document conversion, news, paper and developer search and more, paid per call with USDC on Base, Solana, Polygon or Arbitrum via x402. No account, no API key, free sample on every service.

Output

Returns a JSON object containing the resized image as a base64-encoded string, along with the output width, height, format, and size in bytes, plus the original image's dimensions, format, and size for reference.

Example use cases

Thumbnail generation for product catalog

“Take the product image at https://mystore.com/images/product123.jpg and resize it to 320 wide by 240 tall as a webp at quality 75, fitting it inside those dimensions — I need thumbnails for the catalog grid.”

Convert and compress large PNG for web

“I have a large PNG at https://cdn.mysite.com/hero-banner.png — can you convert it to avif format at 1200 by 630 pixels with quality 80? I want to cut down the file size for faster page loads.”

Normalize user-uploaded avatar to square

“Resize this base64-encoded user avatar image to exactly 256 by 256 pixels in jpeg format at quality 90, using cover fit so it fills the whole square without leaving empty space.”

When to prefer

Choose this endpoint when an AI agent needs to programmatically resize or reformat images on a per-call, pay-as-you-go basis without managing API keys or subscriptions. Particularly suited for agents handling user-uploaded content, generating thumbnails, or preparing images for specific display contexts. Supports both URL-based and base64 inputs, making it flexible for pipelines where the image is already in memory.

Image exceeds the 15 MB size limit
