HTML2PDF Rocket vs Web to PDF

HTML2PDF Rocket is a cloud service that converts a URL or submitted HTML into a PDF or image file. It can execute JavaScript while rendering pages, and its API lists JPG, PNG, BMP, and SVG as image outputs. PDF settings include page size, orientation, margins, grayscale, forms, print stylesheets, and headers and footers. The service is positioned for generating downloadable reports, brochures, and invoices from webpages. Code examples are provided for C#, JavaScript, PHP, Java, and Android, with links to examples for Python, Node.js, Go, and Swift. URL conversion supports SSL, HTTPS pages, and basic authentication. The maker says conversions taking over 30 seconds, or input or output files larger than 6 Mb, need batch or asynchronous parameters. The Free Plan costs nothing and includes 200 credits per month with a 5 Mb per-PDF limit; large PDFs use credits based on network traffic. BOOTSTRAPPED costs $5 a month and includes 500 credits and a 50 Mb per-PDF limit. Free generation stops when credit use reaches 100%, while paid accounts may continue at a slower generation rate.

Web to PDF turns a webpage URL into a file for offline sharing or record keeping. It can produce PDF, JPG, PNG, GIF, or TIFF files, and lists additional conversions from HTML, HTM, or MHT to PDF and PDF to HTML. Page controls cover size, orientation, margins, and zoom, including custom dimensions. Other settings include print layout, removing JavaScript or links, page numbers, grayscale, bookmarks, and a configurable wait time. Its Chromium-based engine can render page content updated by JavaScript. For PDFs, users can apply a text watermark, set a password, or prevent extraction and printing. No account or email is needed. The service says files are machine processed without human review and transferred over HTTPS, but advises against submitting highly sensitive or critical files. Files can remain available for up to one hour, and login-required pages are unsupported. The FAQ says conversions are free, though terms allow frequency limits tied to usage and server capacity.
