PDFWorldEditor opens, reads and transforms your PDF documents right from your phone. WHAT YOU CAN DO Read. Open a PDF, scroll, zoom, jump to any page. Annotate. Highlight, draw, write on a page, add a note. Sign. Draw your signature once, place it wherever you want, and reuse it on your next documents. Assemble. Merge several PDFs into one. Reorder pages, rotate them, delete them. Create a blank document and insert a photo. Compress. Reduce the size of a file too heavy to send by email. Convert. Turn a PDF into an editable Word document, or into images. Scan. Photograph a sheet of paper: the image is straightened, the text is recognised, and you get a PDF you can search for a word in. Edit text. Tap a word in an existing PDF and replace it. Useful for correcting a date, an amount, a name. Print and share. Send the document wherever you want with your iPhone's share sheet. WHAT THERE IS NOT No account required: everything works without signing in. Signing in is optional, with Apple or with Google. It only serves to recognise you: your documents are never attached to an account. No advertising. No subscription, no in-app purchase. No tracker, no analytics. YOUR DOCUMENTS Reading, annotating, signing, merging and reordering pages all happen entirely on your iPhone, offline. Four features need computing power the phone cannot provide on its own: compress, convert, scan and edit text. They send the document to our server in Germany for the time of the computation. We have neither a database nor storage space: the file is not kept after the response. Everything is explained in detail in our privacy policy. App published by HYVRAX, a French company.
