Frequently asked questions

How do I merge JPG images into one image?
Choose your JPG images, arrange their order, select JPG as the output format, choose vertical or horizontal direction, and click Start merging. The tool combines the selected pictures into one file.
Can I combine PNG images online for free?
Yes. Select multiple PNG files and choose PNG output to preserve transparency where possible. Transparent areas remain transparent unless your selected output format or source image does not support them.
Can I merge images side by side or vertically?
Yes. Choose Horizontal to place images from left to right, or Vertical to stack them from top to bottom. Use the alignment option when the images have different dimensions.
Are my images uploaded to a server?
This page merges selected local files in your browser. The tool code does not upload those selected files to a conversion server. If you use third-party browser extensions or other site features, their behavior may differ.
Why might a merged image fail to download?
Very large files can exceed the available memory or canvas dimensions of your browser. Some formats, including certain HEIC/HEIF files, may not be decoded by every browser. Try fewer or smaller images or use a supported input format.
