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.

  1. Upload multiple images: Add up to 9 images at once via the file input. Each image loads into its own cell.
  2. Grid layout control: Choose 1, 2, or 3 columns to arrange your photos. The grid automatically adjusts rows.
  3. Adjustable spacing: Set the gap between images from 0 to 50 pixels for tight or spacious layouts.
  4. Cover or contain fit: Cover mode crops images to fill cells uniformly. Contain mode preserves each image's full aspect ratio.
  5. Custom background: Pick any hex color for the background. It shows through gaps and behind contained images.
  6. 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.

  1. Use similar aspect ratios: Images with similar shapes create the most uniform grid. Mix portrait and landscape in separate batches.
  2. Cover mode for consistency: Use cover fit mode when you want all cells to look the same size without empty background areas.
  3. Contain mode for full images: Use contain fit when every pixel of each image needs to be visible, even if it leaves background gaps.
  4. Order matters: The first uploaded image goes top-left. Use reorder buttons to arrange them correctly.
  5. Resize large images first: Very large images can slow down processing. Resize on /resize-image before combining.
  6. Preview before download: Check the combined result in the preview pane before saving to avoid rework.

When to combine photos

Typical uses for combining multiple images into a single picture.

  1. Social media collages: Combine multiple photos into one grid image for Instagram, Facebook, or Pinterest posts.
  2. Before and after: Merge two photos side by side to show transformations, edits, or progress.
  3. Product comparisons: Place multiple product images in a grid for comparison shots and e-commerce listings.
  4. Portfolio grids: Showcase multiple design or photography works in a single combined image.
  5. Photo strips: Create vertical photo strips by using 1 column layout for a stacked timeline effect.
  6. Mood boards: Combine inspiration images into a single reference collage for design projects.
