What are conversion credits?
Every conversion has a base credit cost that depends on how much processing power it needs. That base cost is then multiplied by the size of your file. Only successful conversions are charged.

Frequently Asked Questions
How are credits calculated?
Each conversion has a base cost — 1 credit for standard conversions, 2 credits for premium browser-engine ones like HTML→PDF. That base cost is multiplied by file size: 1× up to 25 MB, 2× up to 100 MB, and 3× beyond. Use the credits calculator above to estimate any conversion.
Which conversions cost 2 credits?
HTML→PDF, HTML→PNG, and HTML→Image run a full browser engine to render your page, so they consume significantly more CPU and memory and have a base cost of 2 credits.
Do subscription credits roll over?
No — subscription credits reset to your monthly allowance at the start of each billing month. Purchased credit packs never expire and are used only after your subscription credits run out.
Can I combine a subscription with credit packs?
Yes. Subscription credits are consumed first each month, then your purchased credits. Purchased credits never expire.
What happens if I exceed my plan's limits?
You can purchase credit packs at any time to keep converting. No automatic overage charges.
Can I cancel or change my subscription?
Yes. You can switch plans anytime from the dashboard billing tab — upgrades apply immediately with a prorated charge. You can also cancel anytime.
