HTML2PDF.app review
A flexible HTML-to-PDF API with a free tier and Chromium rendering.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
HTML2PDF.app is a hosted web and API service that converts public URLs or raw HTML markup into PDF documents. It uses headless Chromium to render modern HTML, CSS and JavaScript, making it suited to developers generating reports, invoices, pages or other formatted documents. Requests can return PDFs synchronously or run as asynchronous callback jobs. An online converter and WordPress plugin extend its use beyond direct API calls.
The published monthly plans scale by credits, conversion concurrency and PDF size. Free provides 100 credits per month, one parallel conversion, PDFs up to 1MB, all customization options and the WordPress plugin. Startup costs $9 per month for 1,000 credits, three parallel conversions and unlimited PDF size. Standard is $25 per month with 5,000 credits and 10 parallel conversions, while Scale is $39 per month with 10,000 credits and 20 parallel conversions. Paid tiers retain all customization options and the WordPress plugin.
Rendering controls are the standout capability. You can choose page formats or custom dimensions, set margins and scaling, select screen or print CSS media, add HTML headers and footers with page variables, and use CSS page breaks. The waitFor setting delays rendering from 0 to 10 seconds for JavaScript or resource loading, and AES-encrypted PDFs support passwords and permissions. These controls fit document-generation workflows that need predictable layouts. Teams seeking a dedicated screenshot API should compare services centered on image capture, while small and mid-market developers needing PDF output can start with the free plan and move up as volume or concurrency grows.
