Office to PDF

Overview

Documents are converted with LibreOffice, so fonts, tables, images and page layout are kept as closely as an office suite would print them. The file's extension is checked against its contents, and a file that turns out to be another office format is converted as what it really is. Each call accepts one document up to 10 MB. Password-protected documents are not supported.

Endpoint

One host, one path per API. The block below shows this call in four languages; every one of them is the same HTTP request. Making requests covers the timeouts, retries and parameter rules that apply to all of them. The SDKs wrap the same call in a typed client.

Replace your_api_key_here with the key from your dashboard. When the inputs arrive as a list rather than one at a time, batch requests run up to 200 of them through this same API in a single call.

Authentication

Send your key in the x-api-key header. That is the only auth step — there is no token exchange and no per-endpoint scope to configure. Authentication covers creating, rotating and revoking keys.

Parameters

Sent as JSON in the request body. Premium parameters are accepted on every plan but only take effect on plans that include them.

Response

Every API returns the same three top-level keys, so one response handler covers your whole integration: status, error and data. Only data changes shape. Response format covers the envelope, the other output formats and how premium fields are withheld.

}

Response fields

Paths are relative to data. Premium fields are absent rather than zeroed on plans that do not include them, so check for presence instead of comparing to 0.

Errors

Read the HTTP status first, then error for the specific reason. The body names the parameter that has to change. Error handling covers the full status list and which of them are worth retrying.

Use cases

Document Archiving

Store contracts, letters and reports as PDFs so they open the same way everywhere, years later.

Invoice and Quote Delivery

Turn invoices or quotes generated as Word or Excel files into PDFs before emailing them to customers.

Upload Normalization

Accept any office file from users and keep a single PDF copy for previews and downstream processing.

Print Preparation

Convert slide decks and spreadsheets to fixed-layout PDFs for printing or sharing.

Other ways to use Office to PDF

Set up Office to PDF on APIVerve, or reach the same source a different way. Your APIVerve account and credits work on all of them — one key, one balance.
