File formats and limits for Drive

The Delos Drive app allows you to import and query your documents. Here are the accepted formats and their limits.

Supported formats

• Text documents (.docx, .txt, .md, selectable text PDF)
• Presentations (.pptx)
• Spreadsheets (.xlsx, .csv)
• Images with text (.png, .jpg with integrated OCR)
• Audio/transcription (.mp3, .wav, .m4a with automatic transcription)

Limits to know

• Maximum size 50 MB per file
• Page count 500 pages maximum per PDF document
• Images minimum 150 DPI resolution for reliable OCR
• Protected files (password-protected or DRM documents not supported)
• Audio duration 3 hours maximum per audio file

Best practices

• Split long PDFs into chapters for more precise answers
• Name your files clearly to facilitate search in Drive
• Use PDFs with native text rather than scans when possible
