Merging PDF files in a container (Azure Blob Storage)

Question

I have a container in Azure blob storage where I have multiple single page pdf files. I want to merge them right there on container without downloading the files and merging them locally. Is there a way to do it using nodejs?

I found a package called easy-pdf-merge in npm which merges the pdf but cannot find a way to merge them and store the file on azure container itself.

Thanks.

You won't be able to do without downloading the files locally. Alternatively, for minimal footprint at client, you would need a pdf merge library which can support stream as input and output. — krishg

It's not possible to interact with the files without downloading them somewhere; whether to your local machine or a server of some sort.

Is this a problem you could solve with an Azure Function utilising the Azure Storage REST API? It's feasible that you could access the necessary .pdf files, merge them, and then re-upload to the Azure blob storage container. If necessary, you could then also delete the single page .pdf files.
