JPEG to JPG converter

This tool converts JPEG to JPG by altering the file extension while preserving the underlying pixel data. It supports single file and batch workflows, enabling consistent extension naming across platforms common to web publishing and asset management. By avoiding re-encoding, it maintains visual fidelity and minimizes processing time.
Conceptually, the tool reads the source JPEG, validates its signature, and writes a new file with the JPG extension, optionally carrying forward EXIF, IPTC, and XMP metadata. It does not alter image content unless metadata handling requires it, ensuring predictable results in automated pipelines. It covers benefits such as reduced manual renaming, smoother CMS and CDN integration, and fewer platform-specific issues when asset delivery depends on the .jpg extension. Core features include non-destructive extension change, batch mode, and metadata preservation, with clear error reporting for invalid inputs or unsupported targets.
