How licensing actually works.
Two axes — how many developers will use the library and how many production machines will run it. Pick the smallest tier that fits both, or grab an OEM tier when deployment count is unbounded.
Per developer
A developer is anyone on your team who writes code that calls into SelectPdf. Each tier includes a developer count — Single, 5-Developers, or unlimited (Enterprise).
Per deployment machine
A deployment machine is a production server where the library runs. Standard licenses cap deployments (1, 10, or 100). OEM licenses lift the cap entirely.
Unlimited deployments
Pick an OEM tier when you need to ship the library inside your product, or when you cannot easily count where it will be deployed. Same developer count, no machine cap.
License never expires
Every standard license is perpetual. The 1-year maintenance plan covers free upgrades and email support. After that, the version you bought keeps working — renew only if you want new releases.
Maintenance plans
FREE UPGRADES & EMAIL SUPPORTStandard license
Every license on this page ships with a 1-year maintenance plan included — free upgrades and email support.
Included aboveBuy with 3-year maintenance
Lock in three years of upgrades and support up front. Special bundle pricing — pay once, no renewal needed for three years.
See 3-year offer →Buy with 5-year maintenance
Five years of upgrades and support bundled into a single purchase. Best for teams with long procurement cycles.
See 5-year offer →Already a customer?
Renew the maintenance plan on a license you already own — 1 year, 3 years, or restart it after expiration.
Renewal options →What every license includes.
No metered tier. No upsell to unlock features. Every standard license is perpetual, ships with a 1-year maintenance plan, and lets you keep using the version you bought — forever.
Perpetual license
Every standard license is perpetual — once purchased, the version you have keeps working forever, with no kill-switch and no expiry.
1-year maintenance plan
Free upgrades to every new release for 12 months, plus email support for the same period. Bundles for 3 and 5 years are available.
OEM rights (OEM tiers only)
Unlimited deployment machines and the right to embed SelectPdf inside the product you distribute. Available on Single Developer OEM, 5-Developers OEM, and Enterprise OEM.
Maintenance renewal (optional)
After 12 months you can renew the maintenance plan for another year — or skip it and keep using your current version. Renewal is never mandatory.
Perpetual. One-time.
Best when you generate PDFs on-premise on your own .NET servers, want a license that does not expire, and would rather not send documents to a third party.
Monthly or annual.
Best when you would rather call a hosted REST API than install a library — and want a plan priced by conversions per month, with two months free on annual.
