Use it from AI assistants
Every API plan works with Claude Desktop, Claude Code, Cursor, and any MCP client — just ask your assistant to "convert this file". Zero-code, powered by the Model Context Protocol.
Where teams use the file conversion API
Use the API when conversion or compression belongs inside your product workflow.
SaaS Integrations
Embed file conversion directly into upload, export, and customer file workflows.
Automated Workflows
Automate document processing, media transcoding, and batch conversions.
Content Pipelines
Process uploaded files for CMS, DAM, and content management systems.
Developer Tools
Build CLI tools, scripts, and internal automation around documented conversion jobs.
Simple Integration
Get started with just a few lines of code
// Convert image to WebP
const formData = new FormData();
formData.append('file', fileInput.files[0]);
formData.append('input_format', 'png');
formData.append('output_format', 'webp');
const response = await fetch('https://freefastconverter.com/api/external/v1/convert/image', {
method: 'POST',
headers: {
'X-API-Key': 'ffc_live_your_api_key_here'
},
body: formData
});
const result = await response.json();
console.log(result.job_id, result.status_url);Billing and plan notes

Need Higher Volume?
Before a large rollout, contact support to review request rate, file-size needs, webhook behavior, quota planning, and expected support coverage.
API access and file handling
API requests use HTTPS/TLS and API key authentication. Files are handled for the conversion or compression job you request, with result links and retention behavior governed by the configured processing window.
- HTTPS/TLS API requests
- API key authentication
- Visible job status and result URLs
- Webhook event review before production rollout
Webhook Integration
Completion and failure events
Configure webhook endpoints in your dashboard so your app can react when jobs complete or fail. Test events before you depend on them in a customer-facing workflow.
- Job completion events
- Error notifications
- Signature verification
