Html2PDF vs Vector Express v2.0
Html2pdf.app renders either a live URL or a raw HTML snippet into a downloadable PDF, aiming for pixel-accurate reproduction of modern CSS layouts with configurable page orientation and paper size. Requests are authenticated with an API key in a custom header, and the service runs on a monthly credit system charged per megabyte of generated output rather than per request.
Vector Express chains together open-source conversion engines (Ghostscript, UniConvertor, libcdr, hp2xx, and others) to translate vector graphics across CAD and illustration formats including AI, DWG, DXF, EPS, and SVG. The core API is free under shared rate limits, while a pay-as-you-go tier removes those limits and raises the file-size ceiling; it sends no CORS headers, so browser calls need a server-side proxy.
