I'm having to convert PDF files to PNG before sending to Azure Open AI models but this is causing the PNG files to end up several magnitudes larger than the original PDF files and getting close to the 20MB limit.

With the Gemini models, I'm able to send PDF files are ImageContent without issue but when I try this with any of the Azure Open AI models I receive the following error message:

Invalid image URL. The URL must be a valid HTTP or HTTPS URL, or a data URL with base64 encoding.

Unless, is there another way to send PDF files to the Open AI models without having to convert to an image file?
