MergePictures Core Is Now Open Source
Today we are opening the core technology behind MergePictures to the public. The source code is available on GitHub in the mergepictures-core repository.
This is an important step for the project. MergePictures was built around a simple idea: combining images should be fast, understandable, and useful without forcing users to install complicated software. Open sourcing the core makes it possible for developers and curious users to inspect how that idea is implemented and help improve it.
What is being open sourced?
The repository contains the core technology used for image-combining workflows. It is the foundation for arranging images, creating a combined result, and supporting the processing model used by MergePictures.
The public website is a complete product with its own interface, documentation, translations, and deployment configuration. The open-source repository focuses on the reusable core rather than claiming that every part of the hosted website is included.
Keeping that distinction clear helps developers understand what they can reuse and what they should configure themselves in their own applications.
Why open source the core?
Open source improves visibility and gives the community a practical way to participate. Instead of describing the technology only through marketing copy, we can point to code that people can inspect, test, and discuss.
It also creates several useful opportunities:
- Developers can study an image-merging implementation in a real project.
- Product teams can evaluate whether the core fits an internal tool or prototype.
- Contributors can report issues, improve documentation, and suggest technical changes.
- Users can better understand how the browser-based workflow supports local image processing.
Open source does not mean that every use case is automatically supported. Read the repository documentation and applicable license information before using the code in another project.
How to explore the repository
Start with the GitHub repository and read its README for the current setup instructions. Then review the project structure and examples before changing the implementation.
A typical exploration workflow is:
- Read the README and check the prerequisites.
- Clone the repository to a development folder.
- Install the dependencies described by the project.
- Run the available development or test commands.
- Try a small change and verify the generated image output.
The exact commands may change as the repository evolves, so the README and release history should remain the source of truth.
A browser-first approach
MergePictures is designed for a browser-based workflow. On the hosted service, users can select images, arrange them, choose a layout, preview the result, and download a combined image without uploading the source files to the MergePictures.net server.
Making the core public allows developers to examine this approach instead of treating it as a black box. It also makes technical discussions about performance, image formats, memory use, and browser compatibility more concrete.
When adapting the core to another application, developers should evaluate their own privacy requirements, browser support, file-size limits, and error handling. Local processing is useful, but every product still needs clear communication about what happens to user data.
How to contribute
The most useful first contribution is often a well-documented issue. Include the browser or runtime, image formats, approximate file sizes, steps to reproduce the problem, and the expected result.
Documentation improvements, reproducible examples, compatibility testing, and focused code changes can also help. Before opening a pull request, check the repository guidance and keep the change limited to one clear purpose.
Use the tool or build on the code
If you simply need to combine photos, screenshots, receipts, or other images, you can use MergePictures.net directly in your browser. If you are building a product or learning about client-side image processing, visit the open-source repository and start with its documentation.
The hosted tool and the public repository serve different needs: one gives people a ready-to-use image combiner, while the other gives developers a place to inspect, learn from, and improve the core technology.
Frequently asked questions
Is the entire MergePictures.net website open source?
The core technology is open source in the mergepictures-core repository. The hosted website also contains its own UI, content, and deployment pieces, so check the repository contents to see exactly what is included.
Can I use the repository in my own project?
Review the repository README and license information first. They define the permitted use and any obligations that apply to your project.
Do I need to understand image processing to contribute?
No. Reproducible bug reports, documentation updates, compatibility checks, and small improvements are valuable contributions too.
Where can I report a problem?
Use the Issues section of the GitHub repository and include enough technical detail for someone else to reproduce the issue.
