UFLOW

Images & PDF

Compress images, resize them, merge/split PDFs, convert to JPG.

Image and PDF endpoints accept multipart/form-data. An API key with tools:invoke scope unlocks higher limits (600 req/min, 25 MB uploads).

Response shape

Successful calls return ok:true, the tool slug, and a result object with metadata. Processed binaries will stream back with Content-Disposition once the Node-runtime processors ship; until then metadata and a base64 echo are returned so you can test integration.
