PDF tools

Use these endpoints after you already have PDFs — merge, extract, protect, stamp, raster, fill forms, or pack images. Generate from HTML, Markdown, a URL, or a template with POST /v1/pdf. Convert Office files with POST /v1/convert first, then run tools.

Dedicated post-processing endpoints. Tools rate. Failed jobs are not billed.
