How It Works
- Upload Two or More Images. Add your PNG, JPG, or WebP images. The numbered thumbnails show the order they will appear in the composition.
- Choose a Layout and Set Spacing. Pick side by side, stacked, or grid, then adjust the gap and background color to fit your project.
- Preview and Download. Click Combine Images to review the JPEG result. Use Resize All Images to Match first when consistent image sizing matters.
Choose a Layout That Fits Your Images
Pick a layout based on how people will read the finished image. Upload order determines the sequence, and the numbered thumbnails let you check it before combining.
Side by Side
Use a horizontal layout for before-and-after comparisons, product views, or design variations. Images keep their source dimensions and are centered vertically when their heights differ.
Stacked
Choose a vertical layout for a step sequence or tall comparison. Each image stays at its source size and is centered horizontally when widths differ.
Grid
Use a grid for a contact sheet or compact collage. Cells use the largest source width and height, so smaller images are centered in the available space.
When to Match Image Sizes
The regular combine action keeps each image at its original pixel dimensions. Use Resize All Images to Match when a uniform canvas matters: it scales each image proportionally to fit a shared canvas based on the smallest source width and height, then centers it over the chosen background. This can downsample larger images or leave margins around images with different aspect ratios, so skip it when keeping every source pixel at full size is more important.
Understand the Download
The finished composition downloads as a JPEG, which uses lossy compression and does not preserve transparency. The selected background color fills the gaps and any transparent parts of source images. To layer one image over another or adjust its opacity, use Paste & Blend.
Common Questions
How do I create a 2×2 photo grid?
Upload four images, choose Grid, and set the Columns field to 2. The numbered thumbnails show the order; adjust the gap and background before combining.
Do my images need to have the same dimensions?
No. The layouts center smaller images within the shared row, column, or grid cells. Choose a background color for the space around them, or use Resize All Images to Match when a uniform canvas matters.
What does Resize All Images to Match do?
It fits each image proportionally inside a shared canvas based on the smallest source width and height, then centers it over the selected background. Larger images may be downsampled, and different aspect ratios can leave empty space.
What file format does the combined download use?
The combined image downloads as a JPEG. JPEG does not preserve transparency, so transparent areas are filled with the selected background color; the export uses lossy compression.
How do I place one image on top of another?
Image Combiner arranges images side by side, vertically, or in a grid; it does not layer them. Use Paste & Blend to position one image over another and adjust its opacity.
About This Tool
Combine two or more images into one side-by-side, vertical, or grid composition. Adjust spacing and background color, and optionally resize images to fit a common canvas. Image Combiner places images in separate positions; for layered images with opacity control, use Paste & Blend. Processing happens locally in your browser.
