▣ FILE CONVERSION

Word to PDF API: Convert DOC, DOCX, ODT, and RTF

Hosted on ApyHub

What it does

The Word to PDF API converts Word documents into PDFs. Send a DOC, DOCX, ODT, or RTF file as an upload (up to 100 MB), as a URL, or as a base64 string, and get the PDF back either as the file itself or as a signed link you can store or share. Set landscape to true for wide documents such as tables and schedules.

Use it to turn contracts, proposals, and reports into PDFs before sending them to customers, convert user-uploaded documents into one consistent format before storage, or produce PDFs from templates your team edits in Word. To go the other way, use the PDF to Word API. For other document types, use the Spreadsheet to PDF, HTML to PDF, or Image to PDF APIs, and add a "DRAFT" or "CONFIDENTIAL" label with the PDF Watermark API.

Pick the endpoint that fits where your document is: upload endpoints when the file is in your app, URL endpoints when it's hosted elsewhere, and base64 endpoints when the document is already encoded in your data. You can start on ApyHub's free tier with no card required.
