ā Frequently Asked Questions
What is the PDF size limit for Azure AI Search?+
25MB per individual PDF file for indexing. Files larger than 25MB will be skipped by the Azure AI Search indexer.
Does compressing a PDF affect Azure AI Search results?+
No. Azure AI Search indexes the text layer of the PDF. Compressing image quality reduces file size without affecting the text content that gets indexed.
What happens if my PDF exceeds 25MB in Azure AI Search?+
The indexer will skip the file. You need to either compress the PDF below 25MB or split it into smaller sections before adding it to your search index.
Can I store PDFs larger than 25MB in Azure Blob Storage for AI Search?+
You can store them in Blob Storage, but the AI Search indexer will not process files over 25MB. Compress or split the file before indexing.
