An Online Image Merger is a tool that allows you to combine multiple individual image files (like JPG, PNG, GIF, WebP) into a single, larger image. This is incredibly useful for creating photo collages, comparison images, combining screenshots, or assembling images for social media posts, either stacked vertically or arranged side-by-side horizontally.
Zenfied's Image Merger is designed for ease of use and security. It operates entirely within your web browser (client-side), meaning your image files are never uploaded to our servers, ensuring your data remains private and the process is fast.
- Add Your Images: Drag and drop your image files (JPG, PNG, GIF, WebP) onto the designated area, or click the area to browse and select files from your computer.
- Arrange Images (Optional): You can drag and drop the image previews to reorder them. This order will be used when merging.
- Select Orientation: Choose how you want your images to be combined:
- Portrait: Images will be stacked vertically, one below the other. The tool will scale images to match the width of the widest image.
- Landscape: Images will be placed side-by-side horizontally. The tool will scale images to match the height of the tallest image.
- Merge Images: Once your images are arranged and the orientation is selected, click the "Merge Images!" button.
- Download Result: The tool will process and combine the images directly in your browser. Once complete, a download prompt will appear for your new, single merged image file (e.g., `zenfied-merged-image.png`).
- Clear or Start Over: Use the "Clear All" button to remove all uploaded files and start fresh.
- Secure & Private: All image processing happens in your browser. Your files are never uploaded to any server.
- Client-Side Processing: Utilizes your device's power for fast image merging.
- Easy to Use: Simple drag-and-drop interface and clear options for quick image combining.
- Image Reordering: Drag and drop uploaded images to set their merge order.
- Flexible Merging Orientations: Choose to merge images vertically (Portrait/Patayo) or horizontally (Landscape/Higa).
- Supports Common Formats: Works with JPG, PNG, GIF, and WebP input images.
- Completely Free: Merge your images without hidden costs or subscriptions.
- No Installation Needed: Works directly in modern web browsers.
- Direct Image Download: Get your merged image as a single PNG file.
Our Image Merger uses the browser's built-in Canvas API, a powerful JavaScript technology for drawing graphics and manipulating images directly in your web browser.
Here's a simplified explanation:
- When you add images, the tool loads them into the browser.
- When you click "Merge Images!", the script creates a new, blank digital canvas in your browser's memory.
- For Portrait (vertical) merging, the canvas width is set to the width of your widest image. Its height is the sum of all images' heights after they've been scaled to match that common width.
- For Landscape (horizontal) merging, the canvas height is set to the height of your tallest image. Its width is the sum of all images' widths after they've been scaled to match that common height.
- It then systematically "draws" each of your uploaded images onto this canvas according to your chosen order and the selected orientation (stacked vertically or placed side-by-side horizontally).
- Finally, the content of this canvas is exported as a new, single image file (commonly a PNG), which you can then download.
Because all this drawing and combining happens on your computer (client-side), your original image files and the final merged image never leave your device until you download the result.
- Create Collages & Strips: Combine multiple photos into a single artistic collage, a vertical film strip, or a horizontal panoramic-style image.
- Social Media Content: Assemble images into a single, optimized graphic for platforms like Instagram, Facebook, or Twitter.
- Storytelling: Merge sequential images or screenshots to tell a story or illustrate a process, either vertically or horizontally.
- Sprite Sheets: For game developers, combine multiple game sprites into a single sheet (often horizontally) for better performance.
- Simplified Sharing: Send one combined image instead of multiple separate files.
- Visual Instructions: Combine screenshots to create step-by-step visual guides, typically stacked vertically.
Your Images Stay Yours
Client-Side Processing
All image merging operations occur directly within your web browser. Your image files are never uploaded or transferred to our servers.
No File Storage
We do not store, log, or monitor any of the image files you process or the merged results. Your images remain confidential to you.
Absolutely Free
Utilize the Image Merger as much as you need without any cost, registration requirements, or limitations on core features.
By using this tool, you agree to our Terms of Service and Privacy Policy. We are committed to protecting your privacy and providing a secure, serverless experience for image merging.
Is there a limit to the number or size of images I can merge?
While the tool might allow many images, performance depends on your browser and computer's memory (RAM) and processing power. Merging very large images or a high number of images could be slow or cause browser issues on less powerful machines. The final merged image dimensions can also be limited by browser canvas capabilities.
What image formats can I upload and what is the output format?
You can upload common image formats like JPG, PNG, GIF, and WebP. The output merged image is in PNG format to ensure quality and usability, especially when transparency might be involved from PNG inputs.
Can I control the layout or order of merged images?
Yes! You can:
- Reorder Images: Simply drag and drop the image previews to arrange them in your desired sequence before merging.
- Choose Orientation: Select whether you want the images merged vertically (Portrait) or horizontally (Landscape) using the provided option.
Is this Image Merger tool really secure?
Yes, it's designed with security as a top priority. The entire merging process happens client-side, meaning directly in your web browser. Your image files are never uploaded to our or any third-party servers.
Will the quality of my images be affected?
The tool aims to preserve the quality of your original images. When images are scaled to fit a common width (for portrait) or height (for landscape), some resampling occurs. The output is a PNG, which is a lossless format, so quality loss from compression itself is avoided. The final resolution will depend on the dimensions of the input images and the chosen merge orientation.
Can I merge animated GIFs?
Currently, our Image Merger will take the first frame of an animated GIF and merge it as a static image. Merging multiple animated GIFs to create a new, single animated GIF is a more complex process and is not supported by this tool at the moment.
