Supported File Types
This document lists all file types supported by the crawler.dev API for text extraction. In general, the API aims to extract text from any filetype. If you can open the file on your computer and see text, then the API can extract text from it.
Note: Audio file formats are excluded as the API focuses on visual text conversion, not audio transcription.

File Type Detection
The API automatically detects file types using:
- Content-Type header (if provided)
- File extension (if available)
- Magic bytes (file signature detection)
Notes
- Audio formats are excluded: The API focuses on visual text extraction and does not support audio file transcription.
- OCR support: The API supports OCR (Optical Character Recognition) for images, allowing text extraction from scanned documents and images containing text.
- Archive handling: The API can extract text from files within archives (ZIP, TAR, etc.) without requiring manual extraction.
- Format variations: Many formats have multiple MIME types or version-specific types. The API handles these variations automatically.
Format Support Updates
File type support is continuously updated as new formats are added to the API. The list above represents the current supported formats.
