Description

Convert between document formats (PDF, DOCX, EPUB, HTML, DOC, RTF, ODT, TXT).

How to Use

1

1. Host the source document at a public URL (or POST base64 `file` or raw `html`).

2

2. Call with `from_format`, `to_format`, and any format-specific options (`pages`, `dpi`, `page_size`, metadata).

3

3. Save the streamed file, or read `result` from the JSON response on POST.

About This Tool

The unified document endpoint moves between `pdf`, `docx`, `epub`, `html`, `doc`, `rtf`, `odt`, and `txt`, and can also render PDFs as page images (`png`, `jpeg`).

Internally, the service selects the most faithful converter for each format pair — `pandoc` for markup-heavy conversions, `libreoffice` for Office formats, and `pdf2image`/`reportlab` for PDF rendering.

Why Use This Tool

Cross-platform sharing — Convert DOCX to PDF for recipients without Word
Archive normalization — Bring mixed document archives to a single format
HTML → PDF reports — Generate print-ready PDFs from web pages
PDF → images — Render PDF pages for thumbnails or previews

Frequently Asked Questions

What's the highest-fidelity conversion?

Same-family conversions (DOCX ↔ ODT, HTML ↔ Markdown) preserve the most structure. Cross-family (DOCX → EPUB) may flatten some formatting.

Can I watermark the output?

Not via this endpoint. Post-process the returned file with a PDF tooling library.

Are embedded fonts preserved?

Yes for PDF outputs when the source embeds fonts. Otherwise, the closest available font is substituted.
