Turn a photo into a colouring page you can print
Penna is an iPhone, iPad and Android app that turns a photo into a printable colouring page and lets you put your pages together into a colouring book you print at home.
Take a photo of your child, your dog or the whole family, pick a style, and Penna draws clean black-and-white line art, ready for A4 paper.
Free to try: 2 pages to start. No account needed.


How it works
Take or pick a photo
Use the camera or choose a photo from your library: a child, a pet, the grandparents, a favourite place.
Pick a style
Cartoon, classic colouring book or anime, from simple outlines for little hands to detailed line art.
Print, save or share
Print from your phone on A4 (or US Letter), save the page to your photos, or share it as a PDF.
A personalised colouring book starring them
Pick your pages, put them in the order you like and Penna turns them into one PDF book you print at home. Staple it, clip it into a ring binder or take the file to a print shop.
With Penna Pro you can add a cover with a title, in colour from an adventure page or in black and white from any other page.

Draw them into an adventure
Penna can draw the person in your photo into one of 24 scenes: riding a dinosaur, flying to space, diving under the sea, driving a fire engine, shooting hoops and more.
Tap Try another scene and the same person gets a new adventure, without a new photo. Scenes work with photos of one person.

Seven styles, from simple to detailed
Cartoon outlines with big shapes for small children, a classic colouring book look in three levels of detail, and two anime styles. Pick the one that suits the child who will colour it in.

Printed at home, coloured in on paper
Every page is sized for A4 and prints from your phone's own print menu to any home printer. The children colour in on paper; the phone stays with you.
