With iOS 8, Readdle updated their PDF Converter app for iPad with an action extension to quickly convert any webpage to PDF. While the same can be done with Workflow now, I like that PDF Converter saves documents automatically into the app, which can store them in iCloud Drive (and thus on all your devices) without even launching the app after a PDF has been generated.
PDF Converter was updated to version 2.2 yesterday with iPhone support – you can now “print” a webpage to PDF directly from Safari with the tap of a button without having to decide where you want to save the file. In the app, you can tap an iCloud Drive button to open the iOS 8 document picker and switch it to other document storage extensions, and you can also convert the contents of your clipboard or files from Dropbox.
If you don’t want to convert webpages or files, PDF Converter’s action extension shows up in the Photos app, which will let you convert images to PDF documents (handy if you, say, want to annotate screenshots with full-featured apps like PDF Expert).
PDF Converter 2.2 is available on the App Store at $2.99.
