Frequently asked questions
How do I merge multiple images into one?
Add your images to the dropzone, choose horizontal (side by side) or vertical (stacked), adjust the gap and background color, then download the combined result as a single PNG.
What image formats can I merge?
You can merge any image format your browser can open, including JPG, PNG, WebP and GIF. The merged output is always saved as a PNG file.
Are my images uploaded to a server?
No. This tool runs 100% in your browser. Your images are processed locally on your device and are never uploaded, so your files stay completely private.
How are images of different sizes aligned?
For horizontal merges, every image is scaled to a common height (the smallest source height); for vertical merges, they are scaled to a common width. This keeps the row or column neatly aligned.
Can I set the spacing and background color between images?
Yes. You can set a gap of up to 500 pixels between images and choose any background color, which fills the gaps and any empty space around the merged picture.
Is there a limit to how many images I can combine?
There is no fixed limit — you can add as many images as you like. Very large images or a high count may use more memory since all processing happens in your browser.
