Paint by Sticker Online: How to Play Without Buying a Book

Yes. Paint by sticker works online: you pick a picture, the site turns it into numbered mosaic pieces, and your child drags them into place on a screen — or you print the same design as a real sticker sheet. QrdyCraft does both.

If you have searched paint by sticker online, you have probably seen what we see: page after page of books for sale. Amazon, Target, Walmart, the Workman originals. Those are good products — but none of them are actually online. You still wait for a box to arrive, and once the last page is stickered, the book is finished.

"Online" means something different: the picture is made on the web, played on the web, and reprintable forever. Here is exactly what that changes, and where a paper book still wins.

Online vs printed book vs printable PDF

	Printed paint-by-sticker book	Online mosaic maker (QrdyCraft)	Photo-to-PDF converters (pbnify, paint-by-number.com)
How you get it	Order it, wait for shipping	Make it in a browser in about a minute	Upload a photo, download a PDF
Who picks the picture	The publisher	You do — any subject you type	You do — from your own photo
Where the child plays	On paper only	On any screen, drag-and-drop, or on paper	On paper only, after you print
Can you reuse it	No — each page is used once	Yes, replay or reprint any time	Yes, if you keep the file
Sharing with a cousin or classroom	Buy another book	Send a QR code or link	Email the PDF and hope they can print
Cost	~$10–$15 per book	100 free mosaics a month	Free, with watermarks or upsells on some sites
Where it wins	Beautiful art, real peel-and-stick feel, zero screens	Instant, repeatable, shareable, any subject	Turning a real family photo into paint-by-number

That last row matters. If you want your daughter's actual face rendered in numbered paint regions, a photo converter does it better than we do — that is what those tools are built for. And if you want the tactile joy of peeling a real vinyl sticker off a backing sheet, a Workman book delivers it beautifully. What none of them do is let a picture exist in both places at once.

What actually happens to your picture

Every QrdyCraft design starts as a plain silhouette and gets cut into mosaic pieces. Nothing is hand-drawn per order — the shape is traced, then tessellated into polygons, then colored from a palette you choose. Here is the same back-to-school backpack at both stages:

Before — the plain backpack silhouette the design starts from.

After — the same silhouette split into 58 pieces, vibrant palette. This is the medium setting.

The pieces on the right are the ones your child moves. Online, each one snaps into its slot when it lands close enough, so a seven-year-old is not fighting the interface. Printed, the same 58 pieces come out as a numbered sticker sheet and a numbered outline page.

How it works: three steps

1. You describe the picture. Type a subject — "school backpack", "sea turtle", "fire truck" — and pick a palette. Nothing to install, nothing for your child to sign up for. This part is a parent job, which is why the whole thing takes about a minute.
2. You choose easy, medium, or hard. This sets how many pieces the picture gets cut into. Easy suits ages 4–6, medium ages 7–9, hard ages 10–12. More on this below, because the piece count is the part parents most often get wrong.
3. Your child plays it — on screen, on paper, or both. Hand them the tablet and they drag pieces into place. Or hit print and they get a sticker sheet. Send the QR code to grandparents and a cousin in another state can do the same picture on their own screen.

Piece count is the real difficulty dial

Age labels are a rough guide. Piece count is what actually decides whether a child finishes happily or wanders off halfway. Here is what "easy" looks like — the same process, far fewer pieces:

An easy apple: 28 pieces, candy palette. Roughly ten to fifteen minutes for a five-year-old.

Twenty-eight pieces versus fifty-eight is the difference between a happy afternoon and an abandoned one. If your child has never done a mosaic before, start easier than you think — a finished easy picture beats a half-finished hard one every time. Our guide to what age paint by sticker is for breaks the ages down in more detail, and if you are still deciding between formats, paint by sticker vs paint by number covers what each one teaches.

The thing a book cannot do

Two things, really. The first is subject choice: if your son is deep in a dinosaur phase this month and a rocket phase next month, a book gives you whatever the publisher printed. The second is sharing. Every design gets a link and a QR code, so the picture your child made this morning can be on a cousin's tablet by lunch, or on a classroom smartboard, or reprinted for a birthday party favor bag — the same design, as many times as you want.

That is also why we do not hide the free tier: 100 free mosaics a month, which is more than one a day. For most families that is simply the whole product. You would have to be running a classroom to hit the ceiling.

If you want to see finished examples before making anything, the school backpack mosaic in our gallery is a good place to start — every gallery page is a ready-made design you can play or print immediately.

A fair word for the paper books

We are not going to pretend the Workman Paint by Sticker series is bad, because it is not. The illustrations are genuinely well designed, the sticker stock feels good, and there is a specific satisfaction in peeling a real sticker that no screen replicates. If your goal for a long car ride is no screens at all, buy the book. Several parents on Reddit will tell you the same thing, and they are right.

Where the book runs out is repetition and reach. One page, one child, one time. Online, the same picture is infinite and travels.

FAQ

Is there a paint by sticker app my kid can download? There is no download here, and that is deliberate. A parent makes the design on the web at craft.qrdyai.com, then hands the child a link. Nothing to install, no child account, no store page.

Can you do paint by sticker on an iPad? Yes. It runs in the browser on iPad, Android tablets, phones, and laptops. Tablets work best for younger children — the pieces are bigger targets for small fingers than they are on a phone.

Is it actually free? 100 mosaics a month are free, which is more than one every day. Paid plans exist for people who need more than that, but most families never reach the limit.

What age is this for? Ages 4 to 12, with the piece count doing the work: easy for 4–6, medium for 7–9, hard for 10–12. A parent sets it up; the child plays.

Do I have to print anything? No. Playing online is the complete experience. Printing is there when you want a physical sticker sheet — party favors, quiet time on a plane, or a screen-free afternoon.

Can two children do the same picture? Yes. Share the link or QR code and each child gets their own copy to fill in. Nothing is used up, so a design can go to a whole classroom.
