Supported files and upload limits
Every upload screen checks your files before they leave the browser, and the rules are not the same on each one. Read the numbers below as what a screen will stop you doing — the service behind it stays the authority, so a file that passes here can still be refused once it uploads, with a message that comes from that service.
IntelieDocs uploads
The Supported types panel beside the drop zone lists what the picker accepts.
| Check | What the screen allows |
|---|---|
| Accepted types | PDF, PNG, JPG, JPEG, TIF, TIFF, BMP, DOCX, DOC, PPTX, PPT, ODT, XLSX, XLS, CSV, TSV, JSON, XML, TXT |
| Size | Up to 5 MB per file |
| Files at once | No limit |
| Filename length | Not checked |
A rejected file raises a warning naming it — invoice.gif is not a supported file type, or
scan.pdf exceeds the 5 MB limit. Both checks also run on drag-and-drop, so dropping a
file the picker would have hidden does not get it through. GIF is refused either way, even
though other image formats are accepted.
Knowledge Base documents
| Check | What the screen allows |
|---|---|
| Accepted types | .pdf, .docx, .txt, .md, .html, .csv |
| Size | 50 MB per file — the hint reads PDF, Word, text, Markdown, HTML or CSV · up to 50 MB |
| Files at once | Several, but one when you upload a new version of an existing document |
| Filename length | 200 characters |
Rejections carry this screen's own numbers: Exceeds 50 MB limit, Type not allowed.
Accepted: .pdf, .docx, .txt, .md, .html, .csv, and Filename exceeds the 200 character
limit. Please rename the file and try again. An oversize file can also fail with
report.pdf exceeds the 50 MB upload limit. Where the name matches a document already
here, you are asked A document named report.pdf already exists — upload it as a new
version instead? — that check only looks at the first 200 documents, so it can miss a
duplicate in a large knowledge base.
Knowledge Base question and answer imports
| Check | What the screen allows |
|---|---|
| Accepted types | .csv, .xlsx, .xls |
| Size | 10 MB |
| Files at once | One |
The hint reads CSV or Excel (.csv, .xlsx, .xls) — pairs are imported as Unrestricted.
Voice audio
Both surfaces accept audio files — the hints name WAV, MP3 and M4A — and cap them differently.
| Surface | Size | Files at once |
|---|---|---|
| Conversation upload | 100 MB per file — the hint reads WAV, MP3 or M4A up to 100 MB. | No limit |
| New persona | 25 MB per file | Three — Up to 3 short, clean samples of this speaker (WAV/MP3/M4A). |
| Sample added to an existing persona | 25 MB per file | One — A short clean sample of this speaker (WAV/MP3/M4A). |
Select more than three enrolment samples and only the first three are kept.
IntelieKonnect export templates
Upload Template Document, on an export connector's Export Settings tab.
| Check | What the screen allows |
|---|---|
| Accepted types | .doc, .docx |
| Size | 10 MB |
| Files at once | One |
Anything else is refused with Only DOC and DOCX template files are supported.
Profile photo
The picker filters to image files, and that is the only check made in the browser — no size or format guard runs, so an image the service will not take fails only after you choose it.
Where the screens disagree
- PDF is the only type both IntelieDocs and the Knowledge Base accept. IntelieDocs also takes images, PowerPoint, ODT, Excel, TSV, JSON and XML; the Knowledge Base does not. The Knowledge Base takes Markdown and HTML; IntelieDocs does not.
- Size guards range from 5 MB to 100 MB. There is no single figure that holds everywhere.
- Only Knowledge Base document uploads check the filename.
- Only voice persona enrolment limits how many files you can select.
