Supported files | Kwantflow

Kwantflow supports common tender and estimating file types. Support can mean different things:

Upload means the file can be added to an RFQ.
Preview means Kwantflow can show the file inside the app.
AI use means the file can contribute useful evidence to an AI draft when it is readable.

Commonly supported file families

File family	Examples	Typical use
PDF	`.pdf`	Tender documents, drawings, specifications
Images	`.png`, `.jpg`, `.jpeg`, `.webp`, `.heic`, `.tif`	Photos, scans, screenshots
Text and data	`.txt`, `.md`, `.json`, `.xml`, `.csv`	Notes, logs, exports, simple tables
Office files	`.docx`, `.xlsx`	Schedules, scope notes, spreadsheets

Archives and emails	`.zip`, `.msg`, `.eml`	Tender packages and forwarded packages

AI drafting note

AI drafting only uses files when Kwantflow can prepare useful evidence from them. A file may still need manual review even if it uploads successfully.

Unsupported or limited files

Some older or specialist formats may not be supported until they can be handled reliably.

If a file is important and does not preview or draft well, review it manually and include the information in your estimate.
