How to merge images into one
Merging (also called combining, stitching or joining) places several images onto a single canvas so they become one file. This is useful for before-and-after comparisons, contact sheets, panoramic-style strips, social collages and long screenshots. The result is one image you can share or upload anywhere.
This tool offers three layouts.Side by side(horizontal) places images in a single row — good for comparison strips and banners.Stacked(vertical) places them in a column — good for long images and scrolling screenshots.Gridarranges them into rows and columns. After the automatic layout you can drag any image to nudge its position and drag its corner to resize it, so you keep full control over the result.
Which layout should I pick?
For two or three comparison images, side by side reads fastest. For a long vertical story or stitched screenshots, stacked is natural. For many images of similar size — a photo grid, a contact sheet, a collage — grid keeps things tidy. You can switch layouts at any time without losing your images.

Frequently asked questions
How do I combine two images into one?
Drop two or more images into the tool, pick a layout — side by side, stacked or grid — and the tool arranges them onto a single canvas. Drag any image to nudge its position and drag its corner to resize it. When it looks right, click Export to download one combined PNG.
Can I merge images side by side?
Yes. Choose the Side by side (horizontal) layout and every image is placed in a row. Use the stacked (vertical) layout to place them in a column instead, or the grid layout for a multi-row arrangement.
Can I move and resize each image?
Yes. After the automatic layout, click any image to select it, then drag its body to move it or drag the handle at its corner to scale it. The combined canvas updates live.
What format is the merged image?
The combined image is exported as a PNG, which is lossless and preserves transparency. This keeps every source image sharp in the result.
Is the image merger free and private?
Yes. Merging runs entirely in your browser with no upload, and it is free with no sign-up, no watermark and no usage limits.
