MergePNG

What is MergePNG?

MergePng is a browser-based tool that combines multiple PNG files into a single image. Users can arrange their files horizontally, vertically, or in a grid layout. The interface allows drag-and-drop file selection and order adjustment before export.

All processing happens locally in the user's browser. Source images are never uploaded to a server, which keeps private screenshots and design drafts secure. The tool preserves transparent backgrounds when exporting as PNG and checks output dimensions to prevent quality loss.

Output formats include PNG, JPG, and WebP. The service requires no account creation or payment, and adds no watermarks to exported files. Performance depends on device memory and browser canvas limits for very large image sets.
