You can convert the documents to the different file formats through Saaspose.Words such as PDF, XPS, TIFF, HTML, SWF etc. This REST API ensures that the format and quality of original documents is retained. You can either convert document by using the uploaded document on Saaspose storage, Amazon S3 storage etc. or send the document as request stream to Saaspose API. Previously, we have provided examples for different programming languages such as Java, .NET and PHP; we are pleased to announce that you can now use Saaspose.Words REST examples in Ruby as well. You can either invoke these REST operations directly using your own code or you can use a REST client for your particular language. You can upload the document to Saaspose storage or Amazon S3 storage using Saaspose REST API. Once it’s uploaded, you can convert the uploaded file to desired document format using Saaspose.Words REST API in Ruby.
