About the Merge Images Tool
Merge up to 4 images into a single composition for before/after comparisons, product galleries, social media carousels, and blog thumbnails. Choose horizontal (side-by-side), vertical (stacked), or 2x2 grid layout — with adjustable gap and background color. All processing is done locally in your browser.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.
Free — No Account, No Limits
DCPIXEL is completely free with no daily limits, no watermarks, and no registration. We never process your files on our servers, so we can offer this permanently at no cost.
Frequently Asked Questions
How many images can I merge at once?+
Up to 4 images in a single operation. Choose side-by-side (horizontal), top-to-bottom (vertical), or 2x2 grid layout.
Do all images need to be the same size to merge them?+
No. The tool automatically scales images to match the largest dimension in your chosen layout direction. You can also set a fixed cell size for uniform results.
Can I adjust the gap between merged images?+
Yes. A gap slider controls spacing from 0 (seamless) to 20px. You can also set a custom background color for the gap areas.
What is the output format when merging images?+
PNG, which supports transparency and maximum quality. This ensures logos, screenshots, and images with text stay crisp in the merged result.
