    Pick side by side or stacked

    Choose the direction, then keep Same height or Same width on for straight edges, or off to keep each image's own size.

  3. 3

    Adjust order and spacing

    Drag an image's handle onto another to reorder, and set the gap, margin, corners and background colour.

  4. 4

    Download the joined image

    Keep the original size or cap the long side, choose JPG or PNG, and save or copy the result.

Combine images について

Joining two or more pictures into a single file is handy far more often than a full collage: a before-and-after comparison, two product shots for a listing, a row of screenshots for a bug report, a chat conversation captured in several screens and stacked into one tall image, or front and back scans of an ID card on one page.

Choose Side by side to place the images in a row or Stacked to put them one above the other. Nothing is cropped, whatever the sizes and shapes: with Same height (or Same width when stacked) switched on, bigger images are scaled down to match the smallest, so the strip has straight edges and no picture is enlarged. Switch it off and every image keeps its own pixel size, aligned to the top, middle or bottom (left, centre or right when stacked), with the background colour filling the space around the smaller ones.

Spacing adds an even gap between images and the outer margin a frame around them; rounded corners and a transparent PNG background are available too. Drag the round handle on an image onto another to change the order.

The result is saved at the images' own resolution, or limited to 4,096, 2,048 or 1,080 pixels on the long side if you want a lighter file for chat apps. Very long strips are scaled to fit 8,192 pixels and 36 megapixels, a size every modern browser can draw. If you need a grid, a mosaic or cropped cells instead, switch layout in the same tool.

プライバシー

The images are read and joined by this browser tab on your device and saved straight to your downloads; none of them is uploaded, so screenshots of private chats or scans of documents stay with you. Only your spacing, background and format choices are stored locally for next time.

Combine images:よくある質問

Does combining images crop or stretch them?
Neither. Each image is drawn whole and keeps its proportions. With Same height (or Same width) on, larger images are scaled down evenly so all of them share one edge length; with it off, each keeps its exact pixel size and the background colour fills the gaps around the smaller ones. No image is ever enlarged beyond its original resolution.
Can I stack long screenshots into one tall image?
Yes, choose Stacked with Same width on and set spacing to zero for a seamless strip, which is the usual way to share a long chat or web page that took several screenshots. Strips longer than 8,192 pixels are scaled down to fit, so for very long captures you may prefer two separate images.
What output size will the combined image have?
By default it is the natural size of the arranged images: two 4032 × 3024 phone photos side by side with no spacing make an 8,064 × 3,024 px picture. The size shown beside the download button updates as you change options, and the size menu caps the long side at 4,096, 2,048 or 1,080 pixels for smaller files.
Can I put two images side by side for a before-and-after comparison?
Yes, that is what this page is set up for. Drop the before picture first and the after picture second, keep Same height on so the two line up, and add a little spacing with a white or black background for a clean divider. If they arrive in the wrong order, drag the handle on one image onto the other to swap them.
Which format should I save the combined image in?
JPG gives the smallest file and suits photos you will send in WhatsApp, Telegram or email. PNG keeps text in screenshots crisp and is the only choice that preserves a transparent background or rounded corners over transparency. If a site limits upload size, pick JPG and cap the long side at 2,048 pixels.
