Ask HN: Obsolete PDF Format

2 points·tcper··3 comments

The PDF format is bloated, complex, and difficult to edit. When someone asks how to merge two PDFs, it's hard to know what to do without some research, maybe use some software, or script, anyway, you can't easily use it.

So, shall we talk about obsoleting PDF?

There is no reason to abandon PDF. As was already stated the main purpose of a PDF is viewing something as the author has intended, it should not be dynamic like a website. And editing is possible but not the intended use-case (and therefore harder to get right).

As for merging PDFs you first need to know what the user wants. Just merging the pages? Or should AcroForm forms be merged? Should the outline be merged, too? Depending on the answers you can then proceed with the merge. Simply page merging can be done with any tool, merging AcroForm forms or outlines may require more advanced tools.

PDF is actively worked on at multiple fronts, for example, support for HDR, newer image formats, maybe variable width font embedding, better re-flowing capabilities when this is needed (e.g. for small-screen devices)...

And with the ISO PDF 2.0 specification now freely available, anyone can join in :)

PDF lives as a quasi standard "read-only" format in the collective mind. It is the format someone uses when he is reading an ebook, checking his invoices or a report. So widespread that the average user expects he can read it on his phone, browser, PC or even print it as is.

With what should we replace it? None of the other formats have an similar featureset that is commonly used in PDF.
