Which formats can I resize?

JPG, PNG, GIF and WEBP in Batch Resize. Single-image resize in the browser lists JPG, PNG and WEBP up to 25 MB and 25 megapixels.

Is there an official resize SDK?

Picnie does not ship an official SDK. Send an HTTP POST with your API key in the Authorization header.

Can I chain resize with other operations in one request?

No. Call resize, compress, convert, remove-background or watermark as separate requests. Automation workflows can run those steps one after another.
