How to Combine Two Images into One Online

Whether you need a side-by-side comparison image, a before-and-after picture, a dual-candidate document collage, or two photo scans joined on a single sheet, OptiKit's free photo joiner lets you stitch pictures together in seconds right from your browser.

Unlike standard image editors that stretch or squish pictures of different dimensions, our algorithm calculates proportional dimensions automatically. When you combine images side by side, both pictures are matched to an equal height with seamless spacing. When stacked vertically, widths are matched seamlessly. You can also enforce strict file size limits (like under 50KB or 100KB) for official form uploads.

Dual Layout Modes

Switch easily between horizontal side-by-side or vertical top-and-bottom arrangements.

KB Size Compressor

Target exact file weights under 50KB, 100KB, or 200KB for strict online upload portals.

100% Client Privacy

Everything processes locally in your browser memory. No photos are ever uploaded to cloud servers.
