1

Get your API key

Pick a plan and we issue a secret key tied to your account.

2

Send a file

POST any file to a conversion endpoint with your key in the header.

3

Get it back

The converted file streams straight back — processed in RAM, never stored.

Built for files you can’t send just anywhere.

Most conversion APIs upload, queue and store your customers’ files on disk. PrivConvert doesn’t. Every conversion runs entirely in RAM and is wiped the moment it completes — so legal, medical and finance teams can integrate without handing sensitive documents to a third party that keeps them.

  • In-memory processing, zero disk writes
  • Files deleted instantly after each conversion
  • Signed DPA available on Enterprise

Frequently Asked Questions

How is the API priced?
By the number of successful conversions you make each month. Plans start at $9/month for 5,000 conversions and scale up from there. You are only charged for conversions that succeed.
What happens if I go over my monthly quota?
Requests beyond your quota return a 429 status until the next billing cycle or until you upgrade. Your quota resets on the first of each month. No surprise overage bills.
Is there a free tier?
No open free tier — paid plans start at $9/month. If you want to evaluate the API before committing, contact us and we will arrange a short trial.
What about my users’ files — do you store them?
Never. Every file is processed entirely in your server’s RAM and deleted the instant the conversion finishes. Nothing is ever written to disk. This zero-retention guarantee is ideal for legal, medical and financial workloads.
Which conversions are available over the API?
Every server-side conversion on PrivConvert — images, PDF, Office documents, eBooks and archives — is available through a single, consistent REST endpoint pattern.
