Merge Two Photos Side by Side
Use a horizontal layout when you want to compare an original and an edited photo, two product angles, or two design options at a glance. This is the clearest way to merge two photos for a before-and-after view.

A Simple Photo Merge Tool for Real Projects
Photo merge means placing two or more separate images into one finished image. PhotosMerge gives you a clear canvas and practical controls so you can merge two photos side by side, combine two images vertically, or arrange many pictures in a grid. It works well for before-and-after comparisons, product references, social posts, contact sheets, mood boards, and quick visual explanations.
Your files stay on this device while the browser creates the preview and export. That local workflow is useful for personal images, client work, and unpublished ideas. You can add up to 20 images and choose from four layouts, then reorder images, rotate a single picture, duplicate a tile, choose a background, and change the output format before saving.

How to Merge Photos Online
You can merge two photos online in four short steps. The controls update the canvas immediately, so you can compare spacing, order, and background choices before downloading.
- 1
Add your images
Select Add Images, drag files into the editor, or paste images from your clipboard. PhotosMerge accepts JPG, PNG, WebP, and GIF files. The editor keeps the order in which images are added, and every thumbnail has its own remove, rotate, and duplicate controls.
- 2
Choose a layout
Use Horizontal for a side-by-side comparison, Vertical for a tall story or phone screenshot, Grid for a compact collage, or Free when each picture needs an individual position. Switch layouts without re-adding files.
- 3
Adjust the result
Set the gap between images, add a border, choose colors, change the margin, and select a square or circular shape. The advanced panel includes size handling, corner radius, shadow, transparency, and a maximum pixel setting for easier sharing.
- 4
Preview and download
Review the canvas at a comfortable zoom, undo a change if needed, and download JPG, PNG, WebP, or PDF. PNG is useful for transparency, JPG is compact for everyday sharing, WebP is a smaller modern export, and PDF keeps the complete merge on one shareable page.
Merge Two Photos Side by Side, Vertically, or Together
Different image tasks need different arrangements. Choose the layout that matches the way people will read or share your final file, then keep the wording and spacing clear enough that the comparison makes sense without extra explanation.
Combine Two Images Vertically
Choose vertical when the result will be read on a phone or when the images form a top-to-bottom sequence. It works for screenshots, receipts, instructions, and any pair of pictures that should feel like one continuous story.
Merge Two Pictures Together
To merge two pictures together, add both files, choose Horizontal or Vertical, and adjust the gap until the boundary is easy to read. The same workflow also handles merge 2 photos and combine two photos requests without an account.
Combine 2 Images in One File
When you need to combine 2 images or merge two images into one shareable file, check the preview at a comfortable zoom, select a format, and download. Grid and Free layouts make the workflow useful for more than a simple pair.
Photo Merge Features
Local browser processing
Images stay on your device while Canvas creates the preview and export. No upload is needed for the core photo merge workflow.
Four practical layouts
Switch between horizontal, vertical, grid, and free layouts as your images change. The canvas updates without making you start over.
Spacing, borders, and backgrounds
Control spacing, border width, background color, border color, shape, corner radius, shadow, margin, and transparent output.
Simple image controls
Rotate, duplicate, reorder, remove, undo, and redo while keeping each source image visible in the thumbnail strip.
Useful export formats
Download JPG, PNG, WebP, or PDF. PNG supports transparent backgrounds, JPG and WebP are convenient for smaller shared files, and PDF is useful for documents and print-ready sharing.
A mobile-friendly workflow
The editor stacks its preview and controls on smaller screens, so you can combine photos from a phone or tablet without losing the key actions.
Photo Merge Use Cases
Before-and-after comparisons
Show renovation progress, retouching, restoration, fitness results, or a design revision in one image that is easy to scan and share.
Product and design comparisons
Place two product angles, color options, package versions, or interface drafts side by side for a clearer review with a client or team.
Social media collages
Use Grid to combine 2 images or a small set of photos into a balanced collage for a post, story, portfolio update, or event recap.
Screenshots, receipts, and visual briefs
Stack screenshots, receipts, instructions, recipe steps, or reference pictures into one file that is easier to attach to a message or document.
Choose the Right Format and Canvas Settings
A good merge is more than putting pictures next to each other. Think about where the final image will be used before choosing the canvas. For a website or presentation, a horizontal merge can make a comparison readable at a glance. For a mobile message, a vertical merge usually fits the screen better. A grid is useful when every image should have similar visual weight, while Free mode is helpful for a scrapbook-style arrangement. Keep enough margin around the outside edge so the result does not feel cramped. Use spacing to separate images that have different backgrounds, and add a border when a light photo could disappear against a light page. Original sizing preserves detail, but reducing the maximum pixel count can make large exports easier to share. JPG is a practical choice for photographs, PNG is useful for transparent backgrounds and sharp interface screenshots, WebP often provides a smaller file for the web, and PDF is convenient when the merged page belongs in a document. If a browser runs out of memory, try fewer images, a smaller maximum canvas, or a reduced output size. The result is created locally, so processing time depends on the device, image dimensions, available memory, and browser support.

Photo Merge FAQ
How do I merge two photos?+
Add both images, select Horizontal or Vertical, adjust spacing if needed, and choose Download. The browser renders the two photos into one file without requiring an account.
Which image formats can I use?+
You can add JPG, PNG, WebP, and GIF files. Animated GIFs are represented by their first frame. Downloads are available as JPG, PNG, WebP, or PDF. PDF creates a single-page document from the merged canvas.
Are my images uploaded?+
No. PhotosMerge uses local browser memory and Canvas processing for the merge. The site does not need to upload your image files to create the preview or download.
Can I combine more than two images?+
Yes. Add up to 20 images within browser limits, then use Grid, Horizontal, Vertical, or Free mode. Reorder, duplicate, rotate, or remove any tile before exporting.
Does photo merge work on mobile?+
Yes. The editor changes to a stacked layout on smaller screens. Select files from your device, use the same layout controls, and download the finished image when the preview is ready.
Can I export the merged images as a PDF?+
Yes. Choose PDF in the export format options to save the complete merged canvas as a single-page document. PDF is useful for printing, attaching to documents, or sharing a layout without changing the image arrangement.
Can I export a transparent PNG?+
Yes. Enable Transparent background and choose PNG. Transparency is preserved where the canvas has no background color; JPG cannot store transparency.
Is this photo merge tool free?+
Yes. PhotosMerge is free to use for the supported browser workflow, with no signup or watermark added to the exported image. Your browser and device still determine how many large files can be processed smoothly.
Will merging reduce image quality?+
The tool uses source images and your selected output format. Large canvases may be reduced to the maximum pixel setting for browser stability. Use PNG for lossless graphics, JPG for smaller files, or WebP for a compact modern export.
What should I do if a large image will not process?+
Try merging fewer images, lowering the maximum canvas size, or reducing the output size. Browser memory and device limits can affect very large images; the source files remain on your device while you work.
