## About

## What it does
File Merge to PDF combines multiple files into a single PDF, whether you send local uploads or publicly accessible file URLs. It accepts documents, spreadsheets, presentations, text files, images, HTML, Markdown, and existing PDFs, then returns the merged result as a PDF download or an S3 URL.

Use the `files` input when you want to upload content directly, or `file_urls` when the source files already live on the web. The service preserves the order you send, so you can build a report, packet, or appendix in the exact sequence you need. Each request supports up to 10 total files, with 100 MB per file.

`File Merge to PDF` is a good fit for workflows like generating client-facing reports from mixed source files, combining supporting documents into one archive, or turning image-based submissions into a single PDF for review. If you need the output immediately, use the download endpoints; if you want a stored result, use the endpoints that return a URL.

The response is either the merged PDF binary or an object containing a `url` field, depending on the endpoint you call.
