Combine HTML to an image using Go REST API

Easily merge HTML files and export the result to graphic format in Go code. This Go library is designed to combine multiple HTML files into a single image using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native HTML to Image merging solution that provides Go programmers with both great development flexibility and powerful features. By merging files, you can automate your digital HTML/Image workflows and offload some routine parts of the process to fast and efficient HTML processing Go software.

Merge several HTML into an image in Go

You may need to combine HTML files into a single image in many cases. For example, you may want to combine multiple HTML files together before printing or archiving.

HTML merging can be part of a whole integrated document-processing approach for generating images from disparate data sources. Such tasks involve the use of a full-featured HTML/Image manipulation Go library that will process a set of HTML files and merge them together in the shortest possible time, producing a compact and accurate graphical output.
