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.

Common Errors & Troubleshooting

Generated guidance based on this API's documentation, not observed by us. Treat it as a starting point and check against the provider's own error reference.

401 Unauthenticated The Bearer token is missing or the API key is invalid.
Create an API key at cloudconvert.com/dashboard/api/v2/keys and include it as Authorization: Bearer YOUR_KEY.
Task status: error (input file not found) The import URL is not publicly accessible or returns a non-200 status.
Ensure the file URL is publicly reachable without authentication and returns the correct Content-Type.
