AndreaMosaic

Overview

AndreaMosaic is desktop software for building a large photographic image from smaller pictures in your own collection. It is available for Linux, macOS and Windows, and its free Standard version is offered for both personal and commercial use. There is no time limit or demo restriction, but use requires a reference or credit to AndreaMosaic. The maker is based in Wila, Switzerland.

The scale of a finished mosaic depends on the edition: Standard supports up to 200 megapixels and 30,000 tiles, while Professional raises the stated ceiling to 100 gigapixels and 500,000 tiles. For a wider view of this category, see our Photo Mosaic Software list.

Key features

The software assembles mosaics from an image collection and supports a custom tile library, controls for tile reuse, and batch processing. Listed export formats are JPEG, TIFF, BMP, PNG, PSD, PSB and PPM. Edition limits and export options differ:

The download page recommends selected K-Lite Video for Windows codecs for extracting images from video files. That is a Windows-specific workflow note, rather than a general promise of video support across platforms.

Pricing

Standard (Free) costs 0.00 USD per free. The full version has no demo restriction or time limit, and the stated terms allow personal and commercial use with a required AndreaMosaic reference or credit.

Bonus and Professional prices are not listed; checkout lets buyers select a price, but no amount is shown on the page. Bonus adds patterns for people supporting development. Professional is the edition for larger mosaics and collections, with the higher limits and Photoshop-related exports shown above. A free trial is not offered.

Platforms

AndreaMosaic is listed for Linux, macOS and Windows. The Windows download page lists releases for Windows XP through Windows 11 and a portable Windows version. For macOS, it lists one version for macOS 10.7–10.14 and another for macOS 10.15–26. On Linux, the maker says the application can run through PlayOnLinux or the Wine library.

The download page links VirusTotal reports for Windows, the macOS installer, the portable build and the Mojave download, and says those downloads are verified by more than 50 antivirus programs. This is the maker's stated download-check information; users should still choose the package that matches their system.

Who it's for

AndreaMosaic fits users who want to turn a personal image collection into a tiled photographic mosaic, including people who need to process batches or manage tile reuse. The free edition's 30,000-tile and 200-megapixel limits may suit smaller projects; the Professional edition is the stated route for projects needing up to 500,000 tiles or 100 gigapixels. Its free-use terms also make the Standard edition available for commercial work, provided the required credit is included.

Pros and cons

• Pros: The full Standard version is free without a time limit or demo restriction and can be used personally or commercially with credit.
• Pros: Three desktop operating systems are listed, and Standard includes creation and printing features.
• Pros: Higher editions offer larger image-collection and mosaic limits, while Professional adds tile-layer and individual-tile export.
• Cons: Bonus and Professional have no displayed price amount, so their cost is not clear from the listed pricing details.
• Cons: Linux use relies on PlayOnLinux or Wine according to the maker, rather than a listed native Linux package.
• Cons: Giving the software a reference or credit is a condition of the free version's use.

Alternatives

Other options in this category include EasyMoza, phomo, Rapid-Mosaic, PhotoMosaic.ai, PicTiler, Mazaika, Picture Mosaics Online Mosaic Tool and Photo Mosaica.

Verdict

AndreaMosaic provides a clearly defined free starting point for making photo mosaics, with support for commercial use subject to credit and substantial increases in stated capacity in Professional. Its main trade-offs are the missing price amounts for the paid editions and, on Linux, reliance on a compatibility layer. Compare your expected tile count, image collection size, operating system and need for Photoshop exports against the edition limits before choosing.
