How to Splice Images
Upload Multiple Images
Click the upload area or drag in multiple images to splice. Supports JPG, PNG, WebP and other mainstream formats.
Select Splice Direction
Choose horizontal splice (left-right arrangement) or vertical splice (top-bottom arrangement). Select appropriate direction based on content characteristics.
Adjust Spacing and Order
Set spacing between images and background color, drag to adjust image arrangement order. Real-time preview of splice effect available.
Download Spliced Image
Download the spliced large image to your device. Choose output format and quality to meet different sharing scenario needs.
Core Features
Horizontal Splice
Arrange multiple images left-right to splice into one wide image. Suitable for creating comparison images, side-by-side displays, and horizontal long images. Automatically aligns image heights during splicing to ensure neat arrangement. Horizontal splicing is commonly used for before-after comparisons, product displays, and horizontal narrative scenarios.
Vertical Splice
Arrange multiple images top-bottom to splice into one long image. Suitable for creating long screenshots, continuous content display, and vertical narratives. Automatically aligns image widths during splicing to ensure neat arrangement. Vertical splicing is commonly used for screenshot collections, dialogue splicing, and long article illustration scenarios.
Adjustable Spacing and Order
Customize spacing size between images and background color, drag to adjust image arrangement order. Spacing settings make splice results more attractive, order adjustment ensures correct content logic. Flexible parameter configuration meets different splicing needs for professional splice effects.
Batch Processing
Support uploading large quantities of images for splicing at once, no quantity limit (subject to browser memory). Freely adjust each image's position and order to achieve complex splice layouts. Batch processing is suitable for scenarios requiring merging many images, such as long screenshot collections, comic layouts, or multi-image displays.
| Method | Description | Typical Use |
|---|---|---|
| Horizontal | Left-right arrangement | Side-by-side comparison |
| Vertical | Top-bottom arrangement | Long screenshot splicing |
| Grid | Row-column arrangement | Multi-image display |
| Custom | Free arrangement | Creative layout |
Use Cases
Long Screenshot Splicing
Splice multiple screenshots into one long image for complete content display. Web pages, chat records, and long articles often need segmented screenshots. Vertical splicing can merge them into one complete long image for easy sharing and saving. Automatic width alignment during splicing ensures content continuity without misalignment.
Comparison Image Creation
Side-by-side display of before-after comparison effects. Through horizontal splicing, before and after images are displayed side-by-side, intuitively presenting differences. Commonly used for photo editing comparisons, design revision displays, product effect comparisons, etc., allowing viewers to see changes at a glance.
Multi-Image Combination
Merge multiple related images into one for easy sharing. Social media sharing is often limited by image quantity. Through splicing, multiple images can be merged into one for one-time sending. Also suitable for creating photo walls, product galleries, and story layouts, improving sharing efficiency.
FAQ
How many images can be spliced?
Theoretically there's no quantity limit, but practically limited by browser memory. Generally splicing dozens of images is no problem, hundreds may slow down or fail due to insufficient memory. We recommend controlling quantity reasonably based on image dimensions, and processing extra-large splices in batches. Spliced image dimensions increase with image count, so be mindful that output files don't become too large for sharing.
Will splicing affect image quality?
No. Splicing only combines pixel data from multiple images into one large image without resampling or compression, preserving original quality completely. If you choose JPG output format there will be slight compression, choosing PNG output is completely lossless. We recommend PNG format for high quality requirements, JPG format for size-sensitive scenarios.
Can I adjust image spacing?
Yes. You can customize spacing size between images (in pixels) and set the background color for spacing areas. When spacing is set to 0, images connect tightly; larger values create whitespace between images. Reasonable spacing makes splice results more attractive, and background colors can match image dominant tones to enhance overall visual effect.
Can images of different sizes be spliced?
Yes. For images with inconsistent dimensions, the tool automatically handles alignment. Horizontal splicing unifies height (scaled to tallest or specified height), vertical splicing unifies width (scaled to widest or specified width). You can also choose to splice at original dimensions, with size differences filled with background color. We recommend adjusting images to similar dimensions before splicing for neater results.
Can I adjust splice order?
Yes. After uploading images, you can freely adjust image arrangement order through drag-and-drop to ensure correct content logic order. You can also sort by filename or manually specify order. Order adjustment is particularly important for narrative splicing, such as long screenshots and story layouts that need chronological or logical order arrangement.
Which image formats are supported?
Supports JPG, PNG, WebP and other mainstream image formats for splicing, with different formats mixable. Spliced images can be output as JPG, PNG, or WebP format. PNG is suitable for lossless quality requirements, JPG for size-sensitive sharing scenarios, and WebP combines both advantages as the modern web standard. Choose appropriate output format based on intended use.
