Use it when inputs are inconsistent.
Customers upload whatever they have. Operators export whatever their tool gives them. Converterer gives you one place to normalise it before the next step breaks.

How it works
A straightforward conversion API with broad coverage.
Send a file to /convert, specify the output format, and get back a clean converted result. Simple enough for one-off operations, reliable enough for product and automation workflows.
# Convert a Word doc to PDF, get an ID back instantly. curl -u "$CONVERTERER_API_KEY:" \ https://api.converterer.com/convert \ -F input=@report.docx \ -F output_format=pdf # → {"id":"9f1a8e7c-1b9b-4f0a-9d2c-1a2b3c4d5e6f", "status":"queued"} # Result lands at <your-destination>/9f1a8e7c-1b9b-4f0a-9d2c-1a2b3c4d5e6f.pdf when done. # Subscribe to a webhook for instant notification.
Common use cases

User-facing upload handling

Trust
Why people trust Converterer.
A few things that matter when you're putting file conversion on the critical path of your product or workflow.
Running since 2018
Converterer is the rebrand of Paperplane, which has been running as a paid file-conversion service since 2018. The same team and underlying engine.
Files in your storage, not ours
Conversions land directly in your S3, B2, GCS, or Azure bucket. We don't hold output files on our infrastructure beyond what's needed to deliver the job.
Encrypted in transit, deleted after
TLS for every request. Uploaded inputs are deleted after processing, not stored, not inspected, not used for AI training, not sold.
