What are the PDF size limits across Azure services?+
Limits vary by service: Document Intelligence free tier is 4MB (2 pages), paid tier is 500MB (2,000 pages), Azure AI Search is 25MB, Azure AI Studio is 16MB, and Azure DevOps work items allow 60MB.Source: Microsoft Docs ↗
Why does Azure Document Intelligence reject my PDF?+
On the free F0 tier, PDFs must be under 4MB and only the first 2 pages are processed. On the paid S0 tier, the limit is 500MB with up to 2,000 pages. Compress your PDF or upgrade your tier.Source: Microsoft Docs ↗
Can I upload large PDFs to Azure Blob Storage?+
Yes. Azure Blob Storage itself supports very large files, but the Azure services that read from Blob Storage (like Document Intelligence or AI Search) impose their own lower limits on what they can process.Source: Microsoft Docs ↗
What should I do if my PDF exceeds an Azure service limit?+
Compress the PDF to reduce its size, or split it into smaller sections and process each part separately. For Document Intelligence, splitting by chapter or section is the most reliable approach.Source: Microsoft Docs ↗
