File Conversion API Documentation

REST API for converting files (documents, images, audio, video) and downloading results. Use the file conversion API to convert PDF to Word, images to PDF, audio to MP3, video to MP4, and many other formats. Batch conversion supported. API access requires a paid plan (Basic, Pro, or Ultra).

Authentication

Send your API key with every request: Authorization: Bearer YOUR_API_KEY or X-API-Key: YOUR_API_KEY. Create an API key in account settings. See pricing for API plans.

Endpoints

• POST /api/convert — Submit a file for conversion (output format, optional operation).
• GET /api/status/{hash_id} — Poll conversion status until download_ready is true.
• GET /api/download/{hash_id} — Download the converted file.
• GET /api/usage — Check conversion minutes and limits.
• GET /api/operations — List valid operation names for convert.

After submitting a conversion, poll the status endpoint every few seconds; when download_ready is true, call the download endpoint. Use the API for document conversion (e.g. PDF to DOCX), image conversion, audio and video conversion in your app or scripts.
