API billing questions
What counts as one credit?
One successfully optimized image uses one credit, regardless of output format. Validation, decoding, timeout, and encoding failures consume no credit.
Do unused subscription credits roll over?
No. Monthly and annual subscription credits expire at renewal. Purchased top-up credits last 12 months, and the soonest-expiring credits are consumed first.
Will I be charged an overage?
No. API processing stops when your balance reaches zero. You can buy a top-up or change plans from the Polar customer portal.
Are the browser tools part of these limits?
No. Anonymous browser tools stay free and unlimited by image count, and images are processed locally without being uploaded to the API.
