AndreaMosaic

Overview

AndreaMosaic is desktop software that builds a larger picture from a collection of smaller photographs. It suits people who want to make and print mosaics from their own image libraries; its permanent free edition makes it an unusually open-ended starting point, within a firm 200-megapixel and 30,000-tile ceiling.

The full Standard edition is free for personal and commercial use, with a required reference or credit to AndreaMosaic. It has no demo restriction or time limit. For a broader comparison of this category, see our Photo Mosaic Software list.

Key features

AndreaMosaic supports custom tile libraries, tile reuse controls and batch processing. That combination gives users control over which images contribute and makes repeated jobs more practical. It exports to JPEG, TIFF, BMP, PNG, PSD, PSB and PPM, covering common image formats as well as Photoshop-oriented files.

Capacity and some export options depend on the edition. Standard allows 50,000 images in a collection, but limits the finished mosaic to 200 megapixels and 30,000 tiles. Bonus keeps the same tile ceiling while raising the collection limit to 100,000 images and adding patterns and transparency in TIFF and Photoshop formats. Professional is the substantial scale upgrade: up to 100 gigapixels, 500,000 tiles and 2,000,000 collection images, plus Photoshop tile layers and individual tile export. Those higher limits matter for large, intricate projects; they are unnecessary overhead for modest prints.

The download page recommends selected K-Lite Video for Windows codecs for extracting images from video files, so video-to-mosaic work depends on that separate codec setup. The maker links VirusTotal reports for several downloads and says they are verified by more than 50 antivirus programs. Support is handled through a helpdesk ticket form. Its privacy policy says personal data is used for licenses, support, and tax and accounting obligations; payment providers process transactions, are PCI-DSS compliant, and do not share full card numbers with Unyma.

Pricing

Standard (Free) costs nothing. It includes mosaic creation and printing features, up to 200 megapixels, 30,000 tiles and 50,000 images. Because it covers personal and commercial use without a time limit, it is the sensible choice for users whose projects fit those caps and who can include the required credit.

Bonus has custom pricing. It retains the 30,000-tile ceiling, but supports 100,000 images, more tile patterns than Standard, and TIFF/Photoshop transparency. It fits users who need those specific additions but not Professional's much larger mosaic capacity.

Professional also has custom pricing. Its 100-gigapixel, 500,000-tile and 2,000,000-image limits, along with Photoshop tile layers and individual tile export, target demanding projects and workflows that need editable tile outputs. The trade-off is that neither paid edition has a stated amount here, so buyers should weigh those upgrades against their project needs before choosing.

Platforms

AndreaMosaic is desktop software for Windows, macOS and Linux. The download page lists Windows XP through Windows 11 and a portable Windows edition, as well as separate macOS downloads covering 10.7–10.14 and 10.15–26. Linux use is through PlayOnLinux or the Wine library, making it a less direct option for Linux users than a native installation would be.

Who it's for

Choose AndreaMosaic if you want a desktop workflow, control over a reusable image library, and the ability to print mosaics without a time-limited trial. Standard is particularly compelling for personal or commercial projects that stay within its output and collection limits. Bonus suits users who value extra patterns or transparency; Professional is the fit when tile count, image-library size, or Photoshop tile-level exports become the priority.

Look elsewhere if you need a web-based workflow, if you do not want to credit the software when using the free edition, or if your project exceeds Standard's limits but the custom-priced upgrades do not suit your budget.

Pros and cons

• Pros: Standard is permanently free for personal and commercial work, with no demo restriction or time limit, making it practical for recurring projects within its caps.
• Pros: Custom tile libraries, reuse controls and batch processing support more deliberate and repeatable desktop workflows.
• Pros: Professional raises capacity substantially and adds tile-level Photoshop exports for advanced editing.
• Cons: Standard stops at 200 megapixels and 30,000 tiles, which rules it out for larger mosaics.
• Cons: Bonus does not raise the tile ceiling, and both paid editions have custom pricing.
• Cons: Linux users must run it through PlayOnLinux or Wine; extracting images from video also calls for separately selected Windows codecs.

Alternatives

Pick phomo instead if a free Linux, macOS or Windows option in the form of a Python package and CLI utility better suits your workflow; CUDA acceleration requires a compatible GPU and toolkit.

Verdict

AndreaMosaic is an excellent fit for desktop users who want credited, permanent free use and a capable set of controls for building and printing photo mosaics. Its strongest reason to choose it is that Standard is genuinely usable for personal or commercial work, not merely a time-limited preview. Its main reason to look elsewhere is the 30,000-tile cap in Standard and Bonus; projects that need more capacity or professional tile exports must move to custom-priced Professional.
