Document Transformations

Transform your documents on-the-fly using our powerful transformation system. This guide explains how to use transformations to convert, compress, and generate thumbnails from your documents.

​
URL Format

Transformations are applied by adding them to the URL: 
https://cdn.apexxcloud.com/f/{access_id}/{transformations}/path
For example: 
https://cdn.apexxcloud.com/f/abc123/tr-f_pdf,q_auto:standard/documents/contract.docx

​
Basic Format

Transformations follow a simple, consistent pattern: 
tr-{parameter_name}_{value}

​
Combining Transformations

Multiple parameters can be combined using commas: 
tr-f_pdf,q_auto:standard

​

Our document transformation system is organized into two main categories:
  1. Format & Compression - Control document format and quality
