CloudConvert API
Overview
CloudConvert is a powerful file conversion API that supports over 200 formats across documents, images, audio, video, spreadsheets, and more. You create a conversion job via the API, upload or link your file, and receive a download URL when the conversion is complete. It is well-suited for integrating format conversion into automated document workflows.
Beginner Tip
Use the sandbox environment (sandbox.api.cloudconvert.com) with a sandbox API key for free testing — conversions there do not count against your paid quota and are great for developing your integration.
