How many images can I compress in one batch?

About 100 images per browser batch, 25 MB each. The Compress Image API takes one image URL per request.

Which output formats does compression support?

Batch Compression can keep the original format or output JPG or WEBP. The single-image tool lists JPG, PNG and WEBP up to 25 MB and 25 megapixels.

Is there a compression SDK?

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

Does the API store the file in my bucket?

Each REST call sends one public image URL. The response includes a result URL. Picnie does not write files into your S3, R2 or GCS bucket.

Compress images with a REST API

Picnie compresses images through the Compress Image API and a browser batch tool. You send a public image URL, a project id, a quality value and an output format. There is no SDK and no single call that also resizes or removes the background.
