Blink PDF offers six plans sized for every stage of growth, from your first proof-of-concept to millions of documents per month. Every plan ships with the same core rendering quality — the only differences are volume, throughput, and support tier.

Annual billing saves you roughly 17% — about two months free compared to paying month-to-month. The annual amount is prepaid upfront; any overage you accumulate is billed separately each month as you go.

Included in Every Plan

No matter which plan you choose, every Blink PDF render includes:
  • Markdown rendering — clean, spec-compliant conversion from Markdown to PDF
  • PDF/UA-1 accessibility — documents pass screen-reader and assistive-technology checks out of the box
  • Color emoji (COLR/CPAL) — full-color emoji rendered crisply at any size
  • ToUnicode mapping — text in your PDFs is always copy-pasteable and searchable
  • Font subsetting — only the glyphs you actually use are embedded, keeping file sizes small
  • Zero-retention architecture — your content is processed in memory and purged immediately; nothing is stored on our servers

​
How Quota Counting Works

Only successful PDF renders count toward your monthly quota. Failed requests, validation errors, and retries do not consume quota.
The following API calls are always free and never touch your quota regardless of plan:
  • Health-check endpoints
  • Font listing calls
  • Account and admin API calls

​
Overage & Spending Caps

Once you exceed your plan’s included quota, additional PDFs are billed at the per-PDF overage rate shown in the table above. Overage is soft — you are never abruptly cut off mid-month or charged surprise amounts.
On Starter and Pro plans you can set a configurable monthly spending cap. When you hit the cap, the API returns a clear error rather than continuing to bill. This is useful for keeping side-projects and internal tools within a fixed budget.

​
Annual Billing

Choosing annual billing locks in roughly 17% savings (~2 months free) compared to monthly pricing. The annual base is charged upfront as a single payment. Any overage PDFs beyond your quota are still invoiced monthly at the end of each calendar month.
