Image Merger
Combine two photos side‑by‑side or with overlays in your browser.
Upload a background and an overlay image to start merging. Drag the overlay on the canvas in overlay mode.
PNG preserves transparency and subtle blend effects, JPEG is lighter and best for normal photos. [web:282][web:275]
This free Image Merger Tool is designed for quickly combining two photos into a single image without installing any software. Users can upload a background image and an overlay image, then pick from multiple layout modes including overlay, horizontal side‑by‑side, vertical top/bottom, and a before/after split view that shows each image on one half of the canvas. The canvas can automatically match the background, match the overlay, fit both images, or use custom pixel dimensions, which makes it easy to produce assets for social posts, banners, or comparison graphics at the correct size.
In overlay mode, the top image can be dragged to any position on the canvas, scaled from 10% to 200%, and flipped horizontally to create mirror effects or better compositions. The blend mode dropdown supports Normal, Multiply, Screen, Overlay, Darken, and Lighten, allowing users to create double‑exposure looks, texture overlays, and light leak effects similar to dedicated image blender tools. An opacity slider fine‑tunes how strongly the overlay appears over the background, and quick buttons let users center or reset the overlay for cleaner alignment.
The live canvas uses a checkerboard pattern to indicate transparency, so users know exactly what will be preserved when they export to PNG. Once satisfied, they can download the merged image as a high‑quality PNG to retain transparency and subtle blends, or as a compressed JPEG optimized for web and everyday use. All processing happens locally in the browser, keeping images private while delivering a fast, interactive experience suitable for social creatives, comparisons, before/after shots, and quick double‑exposure style edits.
Quick steps to use the Image Merger
Upload both images.
Choose a layout (overlay, side‑by‑side, vertical, split).
Adjust blend, opacity, size, and position.
Set canvas size if needed.
Download PNG or JPEG.
1. Upload background and overlay images
Click “Select Image” in the “Background image” box and choose your first photo.
Click “Select Image” in the “Overlay image” box and choose your second photo.
You can also drag & drop files into each drop area instead of clicking.
Once loaded, the preview canvas updates and download buttons become active.
2. Choose a layout
In the Layout section:
Overlay (default): Places the second image on top of the first; you can drag and blend it.
Side‑by‑side: Shows background and overlay next to each other horizontally.
Top/Bottom: Stacks the two images vertically.
Before/After split: Left half is background, right half is overlay with a dividing line.
Switch layouts any time to see which presentation works best.
3. Adjust blending, opacity and size
When Overlay layout is selected:
Blend mode: Pick from Normal, Multiply, Screen, Overlay, Darken, or Lighten to control how the top image mixes with the background.
Overlay opacity: Use the slider to fade the top image in or out (0–100%).
Overlay scale: Use the scale slider (10–200%) to resize the overlay without distorting it.
These controls help you create double‑exposure, texture overlay, or soft‑blend effects.
4. Move, center, reset, or flip overlay
In Overlay layout you can:
Drag overlay: Click and drag the top image on the canvas (or touch‑drag on mobile) to position it exactly where you want.
Center button: Instantly center the overlay on the canvas.
Reset button: Reset overlay scale and position to default.
Flip button: Flip the overlay horizontally for mirror effects or better alignment.
5. Set canvas size
Under Canvas size:
Match background image: Canvas uses the background image’s resolution.
Match overlay image: Canvas uses the overlay image’s resolution.
Fit both images: Uses a size that comfortably fits both, useful for side‑by‑side or vertical layouts.
Custom (pixels): Enter width and height in pixels (e.g., 1080×1080 for a square social post).
The preview updates so you can see the final proportions before exporting.
6. Download the merged image
Click “Download PNG” to save a high‑quality image with transparency preserved (best for overlays and graphics).
Click “Download JPEG” to save a compressed photo‑friendly version (lighter file size, good for web and sharing).
The file downloads immediately with a timestamped name; you can rename it on your device as needed.
