Just like adult coloring books in the years before, painting by numbers grew from a lockdown pastime into one of the most popular creative hobbies around — and the tools behind it have changed fast. Today a paint by number generator uses AI to turn your own photos into numbered templates in seconds, so instead of random designs you can paint your family, your pet, or a place that means something to you.
This guide covers how paint by number generators work, the best free and AI-powered options in 2026, and when a ready-made custom kit is the easier choice.
Best Paint by Number Generators – A Complete Guide
If you’ve ever tried to paint a picture based on a photo, you probably know already how difficult it is to match the colors. A paint by number generator will give you a hand by easing the process and allowing better planning.
Turning photos into numbered paintings will provide unique results. Each project is unique and more importantly, you can paint whatever you feel like. Stick to the numbers and your painting will slowly start taking on the appearance of your original photo, simple as that.
Furthermore, you can use anything, from oil paints to gel pens, whatever you find suitable for your style.
AI Paint by Number Generators
The biggest change since these tools first appeared is AI. Older generators split an image by simple color zones. Newer AI paint by number generators analyze the photo, identify the main shapes, faces, and fur, and build cleaner, more paintable regions — especially for portraits and pets.
Most run in the browser, convert in seconds, and produce a printable PDF or SVG with a numbered color palette. Free options include DigitPaints and Mimi Panda, usually with a free tier and paid credits for higher resolution or more colors. AI handles busy photos better than the older generators, though clear, well-lit images still give the sharpest result.
These generators output a template you print and paint at home. If you'd rather skip printing and get a ready-to-paint canvas with matched paints and brushes, a custom kit is the alternative — see our custom paint by numbers kits.
Free Browser-Based Generators
Not every generator uses AI. Some older browser tools still work well for a quick, no-cost template. PBNify is the simplest: upload a photo, click the main color zones, and download a numbered outline in a few minutes. It runs entirely in the browser with nothing to install, and it's free, though it can be occasionally buggy — switch browsers if a photo won't convert.
These manual tools give you more control over the color zones but take more clicking than AI generators, and they handle simple, well-lit photos better than busy ones. For portraits and pets, an AI generator produces cleaner regions with less effort.
iOS/Android Paint by Numbers Creator can be used as a mobile application. Indeed, PBNify can be used on any platform, including mobile phones, as long as there’s a browser. This software, on the other hand, must be installed on the mobile device.
Like other apps, this custom paint numbers generator is quite convenient. Users can also tweak the parameters associated with the pictures, such as how many colors they want to use. It’s well packed with features, but it’s a bit finicky to use on a small screen.
The panel for parameters is probably its strongest feature, as it can be edited even after the actual conversion. It’s not excellent when it comes to sophisticated and well detailed pictures and it doesn’t come for free either.
You can probably find more software to convert photos into coloring and painting designs. Some of them are free, others will cost a premium. Some of the premium ones will cost as much as a takeaway coffee, others may cost more than your yearly home insurance.
At the end of the day, it depends on the quality you're after, size, and images.
There are various software programs you'll have to download and install, as well as apps for mobile devices. PBNify is somewhere in the middle, being accessible through a browser with an Internet connection, meaning you can use it on computers, laptops, and mobile devices.
Most importantly, it’s free and despite having a few bugs here and there, it’s totally usable for personal projects.
Working with Custom Paint by Number Generators
Working with a custom paint numbers generator is fairly simple and intuitive. Most programs or applications work on the same principles. You'll have to upload your photo, tweak a few settings, and choose the color palette, then you'll get your result within a few minutes.
Obviously, some services go further than that. While you’ll normally have to print your own images, some services may even do the printing and shipping, yet you’ll obviously have to pay more for such a service. Most people choose to print the generated images themselves.
Avid painters can use both free and premium custom paint numbers generators. Business uses may require a more professional approach, at least in terms of quality. Business uses could also do with more advanced printers and perhaps some image editing software too.
Using a paint by number generator will give access to one-of-a-kind paintings.
The color palette can vary widely and users are encouraged to pick something that's representative of the respective photo, yet an unusual approach is also a good idea for a painting to stand out.
Based on the palette, you can start painting certain parts of the photo that correspond to the chosen numbers. The photo will look like a classic coloring book for adults at first, all white and featuring nothing but lines and frames. As you keep coloring, it will slowly embrace the original photo appearance.
As for what you can use, different painters rely on different tools. Oil paints are ideal for such projects and provide a sense of freedom and art. Besides, they dry very fast. However, it’s not a general rule, as modern acrylic pens can also be used for certain projects.
Most enthusiasts rely on different kits of tools for their projects, so feel free to experiment.
As for sizes, you can get anything between a small page and an impressive mural style design.
How Paint by Number Software Work?
Every paint by number generator out there relies on a different technique to convert photo into paint, yet the final result is usually similar, with various differences in sizes or sharpness. Such tools can complete the conversion within a few minutes only.
Obviously, there are differences when it comes to the actual representation, which normally depends on how intricate the original image is.
There are usually two requirements from the user. First, you’ll need to upload the image you want converted. Second, you’ll have to choose the representative color palette for it, which usually implies clicking on a few areas on it, only to help the software identify the main colors.
Some programs are available directly online over their official websites. Some others are designed for particular platforms, such as computers or mobile devices. A web based paint numbers generator is more accessible because it can be used on any device. After all, you only need a browser.
Finally, there are also some sophisticated tools that will take the image and have an expert turn it into a custom canvas or vinyl design before shipping it over to you. They usually take a few weeks, not to mention the price tag.
Final words
Choosing the right paint by number generator depends solely on personal necessities. It’s worth experimenting and trying a few different tools, but like for anything else, start with the free ones, as they may actually provide the quality you need.
To most people, this is nothing but a creative art hobby, so they’re likely to use generators to paint images they love, landscapes or portraits. But at the same time, it’s also worth challenging yourself every now and then with more intricate designs.
