Merge Two Photos

Merge Two Photos — Free Online Tool

Combine two photos into a single image directly in your browser. This tool lets you merge images horizontally or vertically with one click — perfect for comparisons, collages, before-after shots, and design layouts. All processing happens 100% locally, so your images are never uploaded anywhere. Everything stays private and secure.

How to Use

1. Upload two images — JPG or PNG.
2. The tool automatically merges them horizontally by default.
3. Choose how you want to merge:
   • Horizontal Merge (side by side)
   • Vertical Merge (top and bottom)
4. Click Apply to update the preview.
5. Download the merged image as PNG or JPEG.
   • For JPEG, you can adjust quality settings before saving.

Note: Large images depend on your device’s memory. Check the Notes panel on this page for the maximum supported resolution.

Why Merge Two Photos?

Merging images is useful for many purposes:

• Before/after comparisons
• Social media collages
• Photo references
• Design and mood boards
• Side-by-side presentations
• Combining two angles or two versions of the same picture

With this tool, you can do it instantly — no Photoshop or editing skills needed.

Key Features

• Private & secure: All image processing runs in your browser.
• Automatic merge: Images are merged horizontally by default.
• Two merge options: Choose horizontal or vertical layout.
• Simple preview: Upload → choose layout → Apply → download.
• Flexible formats: Export as PNG (lossless) or JPEG (quality adjustable).
• Format support: Works with JPEG and PNG input files.
• Browser compatibility: Tested on Chrome and Safari.

Tips for Best Results

• Use horizontal merge for comparison graphics or Instagram landscape layouts.
• Use vertical merge for posters, story-friendly content, or full-height images.
• Export as PNG if your images include graphics or need clean edges.
• Export as JPEG for photographs or when file size matters.
• Very tall or wide merged results may exceed device limits — refer to the Notes panel for max supported resolution.

How It Works (Briefly)

The tool reads both images and aligns them based on your selected merge direction:

• In horizontal merge, images are placed side by side with matching heights.
• In vertical merge, images are stacked with matching widths.

The final merged output is rendered on a browser canvas, then exported as either PNG or JPEG. Since all operations are done locally, the process is fast and secure.
