Sejda API review
A focused HTML-to-PDF API with responsive rendering controls and scalable request tiers.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Sejda API is a hosted REST service for converting HTML source code and web-page URLs into PDF documents. It suits teams that need programmatic document generation from responsive web content, including pages that rely on client-side JavaScript, authentication, or delayed resource loading. The API supports configurable page size, orientation, margins, viewport width, print media, lazy loading, and HTTP-authenticated page rendering. Client-side integration is available through CORS, while token authentication protects API access.
Pricing is organized by hourly request capacity. The 200 requests/hour plan costs $12 per month, followed by 300 requests/hour at $24, 600 at $48, 1200 at $96, 2400 at $192, 4800 at $384, and 9600 at $768. Every listed tier includes the Hosted HTML-to-PDF API. This structure gives smaller implementations a clear entry point and lets higher-volume teams increase capacity without changing the product's core function. There is no free plan, so even initial production use starts with a paid monthly tier.
The standout area is responsive web rendering: viewport controls, print stylesheets, delayed rendering, lazy loading, and browser-side JavaScript integration address common requirements for turning modern pages into PDFs. The hosted API runs on Sejda infrastructure, and a self-managed Docker deployment is available for organizations that need processing on their own servers. Sejda API is a good fit when HTML or URL conversion is the central requirement. Teams needing OCR, extraction, merging, splitting, compression, or a wider set of PDF operations should choose a more comprehensive PDF API instead.
