I Gave The New Claude Opus 4.5 a 50-Page PDF. It Handed Me Back a Board Deck.
November 25, 2025 - Anthropic has figured out how to let Opus 4.5 work natively with Microsoft Office files. I’m not talking about reading a PDF. We’ve had that. I’m talking about creation and active editing. Here is what I did this morning to test it. I took a dense, 50-page PDF market research report - the kind that makes your eyes glaze over - and I gave it to Claude.

r/ClaudeAI on Reddit: Problem with Claude Opus and Sonnet 4 creating PDFs
April 24, 2025 -
I've been working on a recipe, and I'll tweak and adjust before asking for a downloadable PDF. I've done this frequently, but both Opus 4 and Sonnet 4 refuse to create one. Instead, they're giving me HTML files to download. Is anyone else having this issue?

To the best of my knowledge, Claude has never supported outputting to PDF, only reading as input. I checked both docs.anthropic.com and asked a friend internally. Are you sure you didn't have some extra 3rd party "voodoo" helping deliver a PDF before that may have broken in the transition to Claude 4?

You could download a PDF version or something that you were working on. As I mentioned, I have a lot of recipes and other things on my desktop that I downloaded from Claude, such as our PDF. It was an option underneath the fly-out menu at the top right
