Limits and import speed

When using the public site (, the limits and import speeds are as follows:

  • Import a maximum of 2,000,000 documents

  • Max 655,360 Unicode characters per document

  • Speed: Overview can ingest 100 Word documents per minute or 500 PDFs per minute, across all users. OCR is slower: 100 pages per minute. (These are rough estimates.)

If you’re using a custom install, you can choose how many concurrent conversions to allow. (Overview-local defaults to running only one conversion at a time.)
