ImageMerge

ImageMerge is a powerful and efficient desktop tool designed to merge images and videos from multiple folders into one cleanly organized, sequential output.

Whether you are cleaning up messy media collections, combining downloads, or organizing your personal library, ImageMerge streamlines the workflow with an intuitive navigation sidebar, step-by-step guidance, and three dedicated operation modes: Merge folders, Add to library, and Tidy a folder.

Key features include advanced duplicate detection (checking file size, extension, and content hashing), flexible file handling options (copy, move, or copy-and-delete), and a safe temporary workspace staging system that ensures your files are processed reliably without risk of interruption.

Built for speed, safety, and ease of use, ImageMerge gives you complete control over your media organization with a clean interface and robust backend.

Features

Three Dedicated Workflows: Easily switch between Merge folders, Add to library, and Tidy a folder to match your exact media organization needs.
Advanced Duplicate Detection: Efficiently detects and removes duplicate files by checking file size, extension, and content hashing with optimized caching.
Flexible File Operations: Choose from multiple handling options including copy, move, or copy-and-delete source files.
Deterministic Media Sorting: Automatically sorts media into predictable groups (images prioritized over videos, ordered by extension) and arranges them into continuous numeric sequences.
Safe Temporary Workspace: Protects your data by staging changes in a secure temporary workspace (using hard links with fallback) and applying them only when processing successfully completes.
Drag-and-Drop & Quick Access: Supports intuitive folder drag-and-drop into source lists and provides a convenient "Open folder" button right after a run finishes.
Custom Prefixes & CLI Support: Add optional custom prefixes to output filenames and automate tasks seamlessly using the built-in command-line interface.
