PDF Tools

Work with PDFs and Office documents—merge, split, convert, or extract pages.

Images to PDF

post

Upload one or more images and receive a single PDF.

• Binary PDF is returned by default.

• To receive a JSON payload with base64, set header Accept: application/json (or send json=1).

• Choose engine via engine param: pdfkit (default), pdf-lib, or sharp (robust for PNGs). Use this when you want to gather screenshots, marketing graphics, or homework pages into a single document that is easy to share.
