Instructions

Software Usage Instructions

Import images: Click “Select Images” or drag images to the upload area. You can select multiple images at once or choose a folder to import.
Select a processing mode:
- Single image collage: Combine multiple images into one long image, horizontal image, or grid collage.
- Batch collage: Group images by filename prefix or a fixed quantity to generate multiple collages in batches.
Adjust image order: In single image mode, you can drag images in the preview area to adjust their order. The interface displays the first 20 images, but all images will be included during processing.
Set collage parameters: Choose a vertical, horizontal, or grid layout, and set the width and height of each image, number of images per row, image spacing, canvas margin, background color, rounded corners, border, shadow, numbering, and filename labels.
Set batch grouping: In batch mode, you can group by filename prefix or by a fixed quantity. After enabling “Merge all images into one,” one unified collage will be generated.
Select output format: JPEG, PNG, and WebP formats are supported. You can adjust the output size and visual quality of JPEG and WebP using the quality slider.
Generate and download: Click “Generate Collage” to preview the result. In single image mode, you can download the image directly; in batch mode, you can download all results as a ZIP archive.

FAQ

A: Vertical layout is suitable for creating long images and step-by-step screenshots; horizontal layout is suitable for comparison images; grid layout is suitable for photo walls, product image layouts, and 3x3 grid images.

A: Import 9 images, select “Grid Layout,” set the number of images per row to 3, then adjust the spacing, margins, and background color as needed.

A: When you select “By filename prefix,” the tool identifies groups based on the separator. For example, product01_1.jpg and product01_2.jpg will be grouped under product01; product02_1.jpg will be grouped into another group.

A: To keep page operations smooth, the preview area only shows the first 20 images. All imported images will be processed when generating, not just the images shown in the preview.

A: No. Image reading, stitching, previewing, and exporting are all completed on the current device. After processing is complete, you can directly download the image or ZIP archive.

A: JPEG is suitable for photos and smaller results; PNG is suitable for images that need a transparent background or detail preservation; WebP is suitable for balancing image quality and file size.

A: You can reduce the width and height of individual images, lower the spacing and margins, or process the images in batches. Very large canvases use more memory, and some devices may not be able to generate them all at once.
