Edit PDF in Go SDK

Use REST API to edit PDF in Go programmatically

When developers modify a PDF document with this Go library, what is actually being edited is the Document Object Model (DOM). Thus, almost any changes can be made to the PDF document represented as DOM. With the provided Go SDK, developers can easily edit a document: modify text, update tables, add images and so on. Just load a PDF, make the necessary changes programmatically and export the result to the same or any supported save format.

Edit PDF in Go using REST API

Our Go library gives developers the ability to modify a PDF document directly by editing its Document Object Model (DOM), which means no additional software needs to be installed.

Edit text in PDF file using Go

The most popular case to edit a PDF file is text editing. With the given software solution, you can add, modify or delete text using Go within the document.

Edit table in PDF file using Go

Another popular PDF editing option is table editing. Our Go SDK allows you to work with tables and text in table cells.

Go developers can add or remove table and table cells, as well as add, edit and remove text within them.

Add an image to PDF file using Go

Besides editing text and tables in PDF, there is another common option: adding images to a document in Go. Go developers can also add an image into a PDF file using DOM.

Edit PDF programmatically

Try this powerful Go SDK and evaluate some options in PDF document editing. Using the following example, load your PDF document and make some changes: add text, add a table and a table cell with text or insert an image into the PDF document:

Upload a document you want to modify
Run code
Upload an image you want insert
Select the target format from the list
