# Document Parser Overview

> Document Parser can automatically parse PDF, JPG, and PNG documents to extract fields, tables, values, and barcodes from invoices, statements, orders, and other PDF and scanned documents.

## Built-in document parser templates

`General Invoice Template` can parse invoices (English only) to invoice id, invoice date, extract total, tax, and line items. Set the `templateId` parameter to `1` to use this template.

## How to classify incoming documents before parsing them?

Use the [/pdf/classifier](/api-reference/document-classifier) endpoint (see below) to automatically sort/detect the class of the document based on AI or on custom keywords-based rules.

For example, you can easily define rules to find which vendor provided the document to find which template to apply accordingly. See [Document Classifier](https://docs.pdf.co/api/document-classifier) for more details.
