Combine photos online

Combine multiple photos into one layout. Pick arrangement, preview the collage, download PNG.

What is a photo combiner?

A photo combiner (also called an image merger or picture merger) lets you combine multiple photos into a single image arranged in a grid layout. Upload 2 or more pictures, choose how many columns to display them in, adjust spacing and background color, choose between cover (crop to fill) or contain (fit entire image) modes, preview live, and download the merged result as PNG. Unlike tools that only merge two images side by side, this combiner supports flexible multi-image grids for collages, comparisons, portfolios, and mood boards — all running locally in your browser.

Photo combiner features

Combine multiple photos into a grid collage with flexible layout controls.

  • Upload multiple images

    Add up to 9 images at once via the file input. Each image loads into its own cell.

  • Grid layout control

    Choose 1, 2, or 3 columns to arrange your photos. The grid automatically adjusts rows.

  • Adjustable spacing

    Set the gap between images from 0 to 50 pixels for tight or spacious layouts.

  • Cover or contain fit

    Cover mode crops images to fill cells uniformly. Contain mode preserves each image's full aspect ratio.

  • Custom background

    Pick any hex color for the background. It shows through gaps and behind contained images.

  • Reorder images

    Use up/down buttons to rearrange the order of images in the grid.

How to combine photos into one image

Simple steps for merging multiple pictures online into a grid layout.

  1. Add your images

    Upload PNG, JPEG, WebP, or GIF files using the add image buttons (up to 9, 15 MB each).

  2. Choose a layout

    Select the number of columns (1, 2, or 3) to arrange your photos in a grid.

  3. Adjust spacing and background

    Set gap size and background color. Switch between cover and contain fit as needed.

  4. Download PNG

    Save the combined image when the preview matches your layout.

Tips for combining photos

Better results when merging multiple images into a grid.
  • 01

    Use similar aspect ratios

    Images with similar shapes create the most uniform grid. Mix portrait and landscape in separate batches.

  • 02

    Cover mode for consistency

    Use cover fit mode when you want all cells to look the same size without empty background areas.

  • 03

    Contain mode for full images

    Use contain fit when every pixel of each image needs to be visible, even if it leaves background gaps.

  • 04

    Order matters

    The first uploaded image goes top-left. Use reorder buttons to arrange them correctly.

  • 05

    Resize large images first

    Very large images can slow down processing. Resize on Resize Image before combining.

  • 06

    Preview before download

    Check the combined result in the preview pane before saving to avoid rework.
