New in 2.0: PDF to Word, JPG to PDF, HEIC to JPG, MOV to MP4 and Unzip, right on your iPhone. Files are never uploaded. Plus a new design in light and dark. Convert files and debug code in one app. DevKit turns PDFs into editable Word documents, photos into PDFs and HEIC photos into JPGs, and gives developers a full kit of formatters, decoders and generators. Everything runs on your iPhone or iPad: your files are never uploaded. FILE TOOLS > PDF to Word: Turn a PDF into an editable Word document (.docx), keeping headings, lists, links, images, headers and footers. Preview the result before you save it.
