Image Merge

There's no strict limit on the number of images you can merge. However, for optimal performance and quality: **Browser limitations**: Typically 20-50 images depending on your browser memory and image sizes, **Grid layouts**: Work best with 4, 6, 9, or 16 images for balanced composition, **Performance considerations**: Larger numbers of high-resolution images may require more processing time, **File size**: Final merged image size depends on layout and individual image dimensions. We recommend testing with your specific images to find the optimal count for your needs.

Our merge tool offers comprehensive layout flexibility: **Horizontal Layout**: Arrange images side by side in a single row, perfect for panoramic effects or timeline displays, **Vertical Layout**: Stack images in a single column, ideal for before/after comparisons or story sequences, **Grid Layout**: Automatically arrange images in balanced rows and columns (2x2, 3x3, 4x4, etc.), **Custom Layout**: Advanced positioning control for creative arrangements and overlapping effects. Each layout includes customizable spacing, alignment options, and automatic resizing to maintain image proportions.

Yes! Complete customization control is available: **Image Spacing**: Adjust gaps between images from 0px to 50px for tight or loose arrangements, **Border Radius**: Add rounded corners to individual images or the entire collage, **Background Color**: Choose any background color or keep transparent for PNG output, **Shadow Effects**: Add drop shadows for depth and professional appearance, **Individual Control**: Adjust settings for the entire collage or fine-tune specific image positioning. Real-time preview shows exactly how your customizations will look in the final result.

Our smart sizing system handles mixed image dimensions intelligently: **Auto-resizing**: Images are automatically resized to fit the chosen layout while maintaining aspect ratios, **Proportional scaling**: No distortion occurs - images scale proportionally to fit designated spaces, **Layout optimization**: Grid layouts automatically calculate optimal sizes for balanced appearance, **Aspect ratio preservation**: Original image proportions are always maintained to prevent stretching or squashing, **Quality maintenance**: Resizing uses high-quality algorithms to preserve image clarity. You can preview the arrangement before finalizing to ensure optimal results.

Absolutely not. All image merging happens entirely in your browser: **Local processing**: Images are processed directly in browser memory using HTML5 Canvas technology, **No server uploads**: Your files never leave your device at any point during the merge process, **Instant deletion**: Processed images are removed from memory when you navigate away or refresh, **Complete privacy**: No image data is ever transmitted to our servers, **Offline capability**: Works completely offline once the page loads. This ensures complete privacy and security for your personal photos and sensitive images.

Flexible output options to meet your needs: **Output formats**: PNG for images with transparency needs, JPEG for standard photos with smaller file sizes, **Quality control**: Adjust JPEG compression from 10% to 100% for size vs. quality balance, **Resolution**: Output maintains the highest resolution possible based on your input images, **Transparency**: PNG format preserves transparency in backgrounds and individual images, **File size optimization**: Choose between maximum quality for printing or optimized size for web/social media. Preview file size estimates before downloading to make informed decisions.

While we don't have preset templates, you can easily create platform-optimized collages: **Instagram Square**: Use grid layout with square aspect ratio for Instagram posts, **Facebook Cover**: Horizontal layout works well for Facebook cover photos, **Pinterest**: Vertical layout is perfect for Pinterest pins, **Story formats**: Vertical 9:16 layouts for Instagram/Facebook stories, **Custom dimensions**: Manually adjust spacing and layout to achieve desired aspect ratios for any platform.
