Convert files, programmatically.
POST a file as multipart form data to /convert/ppt-to-pdf, /convert/pdf-to-ppt, /convert/epub-to-pdf or /convert/mobi-to-pdf on api.printxpdf.com and the converted file comes back in the response. Without a key you get 5 conversions a month per IP address; Pro keys get 300 and API keys 5,000, sent as an Authorization: Bearer header.
Files are limited to 100 MB and jobs to two minutes. They are processed in an isolated container and deleted the moment the response is sent. Errors are JSON with an error message and a code. The whole API is open source in the repository and can be self-hosted on Cloudflare.
