Up to 20 images can be merged at a time. When images are added they appear in the list, and you can freely adjust the order before merging. If you need to merge more than 20, you can first merge some of them and then re-upload the result.
Yes, images of different sizes can be merged. You can use the start, center, and end alignment options to arrange images of different sizes as desired. The spacing between images and the background color can also be adjusted for a clean result.
Choose horizontal layout for comparison images or photos you want to show side by side, and vertical layout for story-style or long infographics. For content that needs to be read in order, like social media card news or recipe images, vertical layout is appropriate. Before/after comparison images are most effective displayed side by side in horizontal layout.
The merged image is saved in PNG format. PNG is a lossless compression format that preserves image quality without degradation. If you are concerned about file size, you can further compress the result using the image compression tool on this site.
Merging multiple images into one is useful for creating comparison photos, photo collages, SNS content, and more. You can combine images directly in your browser without installing any software, making it fast and convenient to get the result you want.
For before/after comparison photos, placing two images side by side horizontally is the most intuitive layout. Recipe steps or tutorial images work well arranged vertically in sequence for easy reading. To display multiple product images in a grid, first merge them horizontally, then merge those results vertically in a two-step approach.
To create a 1:1 ratio collage suitable for an Instagram feed, merge square images horizontally and then crop to the right ratio. For long images to post on social media timelines, connect multiple images vertically to create scrollable card-style content.
