# Uploading Files

## Upload methods

### Drag and drop

Go to the **New File** tab and drag files directly onto the drop zone. You can drop up to 50 files at once.

### YouTube links

Paste a YouTube URL into the upload area. Knowbase downloads the transcript and makes it searchable.

### From connectors

If you've connected Google Drive, Notion, or Dropbox, you can import files directly from those services. See [Connectors](/connectors/connectors.md).

2. **Processing** — text extraction, transcription, or OCR in progress
3. **Ready** — file is searchable and available for chat

**Processing time** depends on the file type. Documents take seconds; long videos may take several minutes for transcription.
