JFIF Merger

This tool merges two JFIF images into a single composite image. It accepts two JPEG/JFIF inputs and outputs one merged JPEG/JFIF file. Merge modes include side-by-side, vertical stitch, and overlay. It is designed for developers, designers, and marketers requiring quick image mashups or paired samples.

Under the hood, the tool reads the two inputs, selects the canvas size based on the mode, and places each image with an optional gap. For overlays, it blends pixels by averaging while preserving color profile; for side-by-side or vertical stitches, it aligns centers and uses crisp seams. It preserves color profiles and attempts to retain basic metadata where possible.

The resulting image supports workflows such as rapid prototyping, client previews, or asset consolidation. Typical use cases include showing before/after comparisons, presenting two product variants, or creating composite thumbnails for galleries. Advanced users can adjust output quality to balance file size and fidelity.
