Why is pdfRest the best API to convert files to PDF?

pdfRest offers the best solution for converting many common file formats to PDF, because it supports robust formats, standardizes PDFs, and includes adjustable controls.

Robust Format Support

This one single tool will take just about any file you throw its way and convert the contents to a PDF document. Works with all of the following:

  • Word (.doc, .docx)
  • Excel (.xls, .xlsx)
  • PowerPoint (.ppt, .pptx)
  • PostScript (.ps)
  • Encapsulated PostScript (.eps)
  • JPEG (.jpg, .jpeg)
  • TIF (.tif, .tiff)
  • BMP (.bmp)
  • PNG (.png)
  • HTML (.html, from URL)

Standardized PDF Documents

Not all PDFs are created equal - many PDF conversion tools lack the support to generate complex PDF documents that meet all requirements by the International Organization for Standardization (ISO). This can lead to painful problems downstream in your workflows.

With pdfRest’s Convert to PDF Tool, all files are optimized using high-quality Adobe® PDF Library™ technology to ensure consistent and reliable compliance with PDF ISO 32000 specifications.

Adjustable Controls

Fine-tune PDF output files and optimize for your specific use cases with adjustable parameters to support:

  • Creating tagged PDFs from Office files
  • Compressing and downsampling PDF images
  • Setting page size, margins, and orientation for HTML conversion
  • And more!
