THM to JPG

About This Tool

This tool converts THM thumbnail images to JPG for better compatibility with mainstream software and web platforms. It targets photographers, developers, and publishers who rely on JPG assets in production, distribution, or on-device use.
Conceptually, the tool decodes THM data, renders a bitmap, and re-encodes it as JPG. It supports batch processing, adjustable JPEG quality, and optional resizing to adapt to target dimensions, ensuring efficient delivery without re-encoding artifacts beyond the chosen quality.
Core differentiators include a dedicated THM-to-JPG conversion path optimized for speed, loss-optimized compression, and a simple file-upload workflow that yields downloadable JPGs with metadata on size and dimensions.
Common use cases include converting thumbnails for CMS galleries, preparing assets for social platforms, and converting archived content for long-term compatibility. The tool focuses on domain logic and data flow, without relying on client-side UI specifics.
