Merge Images Online

Merging lets you build collages, single files from multiple photos, before/after strips, and layouts for social posts and websites—without desktop software.

Benefits of image merging

• Collages: Combine photos into one layout.
• Comparisons: Place images side by side for before/after or A/B views.
• Social content: Create wider or taller visuals for feeds and stories.
• Fewer files: Share or archive one image instead of many.
• Flexible layout: Horizontal, vertical, or grid to match your idea.

1. 1Upload multiple images: Add two or more images—JPG, PNG, WEBP, GIF, BMP. You can select several files at once.
2. 2Choose merge direction: Pick horizontal (side by side), vertical (stacked), or a grid / collage layout.
3. 3Arrange images: Drag to reorder. Order defines left-to-right or top-to-bottom placement in the result.
4. 4Adjust settings: Set spacing between images, background color, and grid options where applicable.
5. 5Merge and download: Download the combined image in your chosen format.

Pick a method that matches your design goal.

Horizontal merging

Places images left to right—great for panoramas, before/after rows, and wide banners.

Vertical merging

Stacks images top to bottom—ideal for tall collages, step lists, and mobile-first layouts.

Grid merging

Arranges images in rows and columns—useful for photo grids, mood boards, and multi-image tiles.

Masonry layouts

A grid forces every image into one box, which suits a set of matching photos and fights a mixed one. Masonry fixes the column width instead of the box, lets each image keep its own height, and drops the next image into whichever column is currently shortest. Portraits and landscapes then sit together without cropping or padding, and the columns end at roughly the same depth. It is the layout to reach for when the images were not shot to match.

Photos rarely arrive the same size, and how a merger handles that is most of what separates a clean sheet from a clumsy one. Keep proportions matches heights across a row and widths down a column, so every image keeps its shape and a small one is never enlarged to fill a box it does not fit. Match the largest gives every image an identical box — the right choice for a regular grid. Match the smallest does the same in the other direction, trading size for a sheet that stays small. Whichever you pick, the fit control decides what happens inside each box: fit leaves the background showing around the edges, fill crops to cover it, stretch distorts to the exact shape, and original size draws the image at its own scale.

Ask for a 2 × 2 grid and hand over ten images and something has to give. Rather than dropping the extras, the merger continues onto a second sheet, and a third, filling each grid in order — and the last sheet is only as tall as the rows it actually uses, so a final pair of images does not sit above two rows of empty background. When a merge produces more than one sheet you can download them individually or take all of them as a single archive.

The tool combines your images into a single composite in order, applies spacing and background, then exports the result.

Merging process

• Analysis: Reads dimensions and properties of each image.
• Sheet size: Computes width and height from direction, spacing, and grid.
• Placement: Positions each image in order with your spacing.
• Resize if needed: Aligns dimensions along the merge axis with quality-aware scaling.
• Render: Draws everything onto one sheet.
• Export: Encodes the sheet to PNG, JPG or WebP.

Powered by optimised image processing algorithms.

Free merges up to 10 images at a time, each up to 25 MB, and exports a sheet up to 4096 px on its longest side. Every arrangement is included — row, column and grid — as are all three output formats. Pro raises the count to 100, removes the per-image size cap, and lifts the sheet ceiling to the largest a browser can save, alongside masonry layouts and export quality control. There is an upper bound either way, because a very long row of large images asks for a sheet no browser will allocate; when that happens the sheet is scaled to fit and the page says so rather than quietly producing nothing.

Follow these tips for cleaner results.

Image selection

• Prefer similar lighting and color tone across images.
• Similar aspect ratios reduce heavy scaling.
• Pick images that read well together at a glance.
• Think about final width/height for where you will publish.
• Start from high-quality sources when possible.

Layout considerations

• Use consistent spacing between cells or strips.
• Align edges and baselines for a polished look.
• Preview on mobile if that is your main audience.
• Keep important subjects away from crop edges.
• Check the merged image at the size you will publish.

Teams and creators use merging across channels.

A few points that help you plan better merges.

Why merged layouts matter

• Collage-style posts often get more engagement than single images on visual platforms.
• Side-by-side comparisons can clarify product or design differences quickly.
• Grids help organize many thumbnails in one shareable asset.
• One merged file can be easier to email or upload than many attachments.
• Consistent spacing and alignment make compositions look intentional and professional.
