Open Source Alternatives to PhotoJoiner
Photo Collage Maker is a browser-based alternative for users who need this focused result without installing a proprietary desktop app or entering a larger hosted workflow.
This research compares that workflow with PhotoJoiner while keeping the outbound source link at the bottom after the analysis.
Why Photo Collage Maker fits
TextFaker can implement local photo joining and collage grids with horizontal, vertical, and matrix layouts, plus deterministic validation for image counts, output dimensions, and file generation.

Detailed research
Positioning
PhotoJoiner is the closest name-level competitor for simple joining. TextFaker should include explicit horizontal and vertical join modes, not only decorative collage templates.
- Side-by-side preset.
- Vertical stack preset.
- Grid contact sheet preset.
- Custom canvas size preset.
Implementation guidance
A deterministic joiner can calculate canvas size from source dimensions and selected mode. For social presets, calculate source crop or letterbox rectangles from target slots.
- Natural-size join mode for exact sum of widths or heights.
- Fixed-canvas mode for social outputs.
- Fit mode preserves full source image.
- Fill mode crops and reports source crop rectangle.
Demand evidence
Public discussions include users asking for two photos side by side, multiple pictures in a bigger image, and vertical collages that do not get cropped by Instagram.
- Side-by-side requests map to horizontal join.
- Instagram vertical issue maps to fixed aspect presets.
- Large photo spread request maps to auto grid.
Testing path
Photo joining has the cleanest deterministic test path among collage workflows. A fixture test can know the exact output size before rendering.
- Two 100x50 images side by side produce predictable width and height plus gap.
- Three 80x120 images stacked produce predictable height.
- Grid preset reports expected rows, columns, and slot rectangles.
- Exported Blob has selected MIME type and nonzero byte size.
Research notes
- PhotoJoiner's official page describes templates, grids, stickers, text tools, doodles, fonts, and detail controls for collage creation.
- PhotoJoiner's app listing also describes joining multiple photos horizontally, vertically, or in a grid, which maps closely to deterministic TextFaker layouts.
- Public Reddit demand repeatedly asks for putting photos side by side, vertically, or into large combined images.
