"Put images side by side" is one of the most common image editing tasks, and one of the most unnecessarily complicated in traditional tools. Photoshop requires layers and canvas resizing. Canva forces template selection. Paint requires manual positioning.

MergeFrame reduces this task to its essence: open the site, drop two images, and export. The 1×2 horizontal layout is the default because it's what most people need. Both images get equal space, equal proportion, and clean separation.

Beyond the basic 1×2, you can extend to Strip of 3 or 1×4 for multi-image sequences. The same simplicity applies: just add more images to the strip. Cell spacing is adjustable from 0px (no gap) to 20px (generous breathing room).

Common uses: comparing two designs side by side, showing product before/after, placing screenshots next to each other for documentation, creating social media comparison posts, and building email newsletter image headers from multiple photos.
