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

​

1. Format & Compression - Control document format and quality
