The open-source, self-hosted alternative to CloudConvert
CloudConvert is a mature hosted converter and API. Vistalyth Tools is the self-hosted alternative when conversion should happen inside your own infrastructure, with pipelines you control.
Vistalyth Tools vs CloudConvert
| Vistalyth Tools | CloudConvert | |
|---|---|---|
| Deployment model | Self-hosted on your server | Hosted web service |
| File processing location | Your infrastructure | Files are uploaded to a vendor-hosted service for processing |
| Cost control | Free AGPLv3; limits are your hardware | Usage-based and plan-based cloud pricing |
| Offline / air-gapped use | Supported when deployed inside your network | Designed for browser-based online use |
| Beyond file conversion | Image, video, audio, PDF, and files | Hosted conversion across many file categories |
| Source and auditability | Source available under AGPLv3 | Vendor-operated service; source availability is not the product model |
| Automation | REST API and pipelines in your deployment | Hosted API and browser workflows |

One stack, all five file types
CloudConvert is broad and API-friendly for conversion. Vistalyth Tools converts across image, video, audio, PDF, and file formats, then adds compression, editing, OCR, transcription, and local pipelines.
What you do today with CloudConvert
You send files to CloudConvert's cloud, wait for the conversion, and download the result, often wiring it into an app through the hosted API and paying per conversion.
Why that matters for sensitive files
Every file that hits the API leaves your network, and the bill scales with volume. For user uploads or internal documents, a third party handles your data and you inherit their retention terms, none of which works in an air-gapped or on-prem setup.
