About this app

PaperKit is a simple, free PDF toolkit for your phone. Fill in a form, sign it, tidy up the pages and send it on, without a computer and with no sign-up needed.

FILL & SIGN
• Type on any PDF form, including flat and scanned ones with no form fields
• Text snaps onto the printed blank lines at a matching size
• Draw your signature once and place it on any page; resize and move it freely
• Add initials and today's date in a tap
• Fill interactive PDF form fields directly

SMART FILL
• Smart fill finds the blanks on a page and fills them in from My details: name, address, email, phone, date of birth and more
• Your details stay on your phone. Only the page being filled is sent to be read, and it is deleted as soon as it has been read
• Review everything smart fill placed before you save

PAGE TOOLS
• Rotate, reorder and delete pages
• Extract pages into a new PDF, or split a document into parts
• Merge several PDFs into one

PRIVATE BY DESIGN
• Everything except smart fill works offline, on your device
• Your files are kept in the app's private storage, not uploaded anywhere
• Your details and signatures are stored encrypted on your device
• No ads

WORKS WITH YOUR APPS
• Open PDFs from Files, Drive, Gmail or any app with "Open with PaperKit"
• Share the finished PDF to email, chat or cloud storage
