Use Visualforce PDF Rendering Service with Apex Blob.toPdf() (Spring ’26 Release Update)

Posting on my blog after years!

I’ve mostly been someone who writes more code than stories.

Diagrams, code, flows — that’s usually how I express.

In between, AI happened.

And whether someone likes it or not, it has become a meaningful part of how we think and communicate.

I’m writing about this because it directly relates to something we are working on right now. 

The Spring ’26 update doesn’t solve our document rendering challenges around generating complex documents with richer fonts and CSS support — which is also why we’ve had to design a custom, alternate document rendering approach that also aligns with compliance and regulatory needs. 

But the Spring ’26 update removes the dependency on Visualforce, which is still a step in the right direction toward decoupling backend document generation from legacy UI technologies.

While writing this (with a bit of help from AI 🙂), I feel like continuing from here.
