Image Combiner

Join photos or screenshots vertically or horizontally into one image.

HEIC photos load an additional local decoder on first use; large originals can take longer to process.

Choose screenshots in reading order, move them up or down as needed, then choose a vertical layout and output width. Generate and inspect the full download.

How to use

Combine screenshots into one long image

Join photos or screenshots vertically or horizontally into one image.

Step by step

  1. Provide the source using: Combine your images.
  2. Set: Direction / Maximum width per image / Space between images / Output format. Use the reference below to choose the options that fit your task.
  3. Choose: Combine images. Inspect the result before copying, downloading or using it elsewhere.
  4. Choose screenshots in reading order, move them up or down as needed, then choose a vertical layout and output width. Generate and inspect the full download.

Choosing the settings

OptionWhat changes
DirectionChoose two or more images, reorder them and select a vertical or horizontal layout. Each image is scaled proportionally only when it exceeds your selected width or height. We do not crop or enlarge small images. The combined result keeps the full content of each image, with smaller images centered.
Output formatPNG keeps transparent regions and gaps. JPEG fills them with white and uses lossy encoding. Resizing can reduce detail; exported metadata is removed and browser color rendering may differ. HEIC inputs are decoded locally and re-encoded. This tool supports static JPG, PNG, WebP and HEIC, not animations or SVG.

Example and expected result

Two 600 × 400 screenshots joined vertically at width 600 with no gap produce a 600 × 800 image. Repeated headers remain visible: this arranges whole images and does not remove overlaps automatically.

If it is not working

  • The output is limited to 8192 pixels per side and 16 megapixels. Long screenshots can exceed this even with few files. Choose a smaller width or height, or fewer images, then retry. We never change your dimensions silently to fit the limit. Processing stops after 30 seconds.
  • Inspect the exported file at its actual pixel size, especially text, edges and transparent areas. A preview that looks good when reduced can still have visible defects in the downloaded image.
  • If an image is rejected, check its decoded dimensions as well as its file size. Export a supported still image from the original app and retry with fewer pixels; renaming an extension does not convert the file.

Join screenshots and photos in order

Choose two or more images, reorder them and select a vertical or horizontal layout. Each image is scaled proportionally only when it exceeds your selected width or height. We do not crop or enlarge small images. The combined result keeps the full content of each image, with smaller images centered.

Does this stitch panoramas automatically?

This tool places complete images next to each other. It does not align overlapping scenes, remove repeated screenshot sections or create seamless panoramas. Original files remain unchanged, and nothing uploads.

Why is my combined image too large?

The output is limited to 8192 pixels per side and 16 megapixels. Long screenshots can exceed this even with few files. Choose a smaller width or height, or fewer images, then retry. We never change your dimensions silently to fit the limit. Processing stops after 30 seconds.

What happens to transparency and quality?

PNG keeps transparent regions and gaps. JPEG fills them with white and uses lossy encoding. Resizing can reduce detail; exported metadata is removed and browser color rendering may differ. HEIC inputs are decoded locally and re-encoded. This tool supports static JPG, PNG, WebP and HEIC, not animations or SVG.
