Swift Merge PDF REST API

Combine PDF using Swift REST API

Easily merge PDF files together in Swift code. This Swift library is designed to combine multiple PDF files into a single file using the REST API, i.e. by passing HTTPS calls over the Internet.

This is a professional Cloud-native PDF merging solution that provides Swift programmers with both great development flexibility and powerful features. Joining PDF files together is often used when it is necessary to create a set of documents of the same structure, each of which contains unique data. By merging PDF files, you can automate your digital workflows and offload some routine parts of the process to fast and efficient PDF processing Swift software.

Merge multiple PDF into one in Swift

You may need to combine PDF files together in many cases. For example, you may want to combine multiple PDF files together before printing or archiving.

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