The web is full of people searching for how to combine pictures online, and the answers they find are almost universally disappointing: tools that upload your photos to unknown servers, editors that require account creation before the download button works, 'free' services that watermark output, complex software recommendations (Photoshop, GIMP) for what should be a simple task. MergeFrame solves the combining-pictures problem at its root: the tool processes your photos in your browser using the Canvas API, so there's genuinely no upload, no server dependency, and no account infrastructure to gate the export. Combining pictures covers a wide range of practical needs: putting two photos side by side for before-and-after comparisons, creating a 2×2 grid of product photos for an online listing, merging trip photos into a single collage to share in a group chat, combining screenshots into one image for a bug report or tutorial, or assembling a 3×3 mood board from inspiration images. The grid layout options cover all of these: 1×2 for side-by-side pairs, 1×3 for horizontal strips, 2×2 for balanced squares, 2×3 for landscape compositions, and 3×3 for comprehensive nine-image collages. Each photo is proportionally fitted — if one image is portrait and another is landscape, both fit their cells without cropping. Spacing (0–20px) and optional borders give you control over the visual separation between combined pictures. The download is a single PNG file containing all your photos in the grid arrangement you designed. This single-file output is the key advantage: instead of sending five separate photo attachments, you send one. Instead of uploading nine screenshots to a bug tracker, you upload one combined image. Instead of posting three separate Instagram photos, you post one striking grid.
