# Merge Various Document Type

> Merge PDF from two or more PDF, DOC, XLS, images, even ZIP with documents and images into a new PDF.

## `POST /v1/pdf/merge2`

<Warning>We do not support images in the HEIC format (Apple’s image format) or the WEBP format.</Warning>

<Warning>The total combined size of all input file URls must not exceed **2 GB**. Requests that exceed this limit will not be processed. </Warning>

This endpoint is similar to [/pdf/merge](/api-reference/merge/pdf) but it also supports `zip`, `doc`, `docx`, `xls`, `xlsx`, `rtf`, `txt`, `png`, `jpg` files as source.

We recommended to use this endpoint in `async: true` mode because it may need to convert source documents to PDF.

This endpoint also consumes more credits because of the internal conversions.

## Attributes

<Note>Attributes are case-sensitive and should be inside JSON for POST request. for example: `{ "url": "https://example.com/file1.pdf" }`</Note>

<Note>
  **Inconsistent URL Encoding in cURL Output:** When using cURL to make API requests, the output JSON may show URL characters encoded as Unicode escape sequences. For example, the ampersand character (`&`) may appear as `\u0026` in the cURL output. This is normal JSON encoding behavior and does not affect the validity of the URL. The URL will function correctly when used, as JSON parsers automatically decode these escape sequences. If you're parsing the response programmatically, your JSON parser will handle this conversion automatically.
