Cloudmersive Document and Data Conversion vs Vector Express v2.0
Cloudmersive's Convert API turns web pages and HTML into PDF or PNG screenshots, transforms Word/Excel/PowerPoint files into PDF and other office formats, and reformats images across 100+ file types including HEIC, PSD, and TIFF. It sits inside Cloudmersive's broader multi-API platform under a single API key, with a free tier of 600 calls/month that never expires.
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.
