Lossless JPEG Toolbox 3.2

Lossless JPEG Toolbox is a focused utility for editing, optimizing, and auditing JPEG images without introducing any new compression artifacts. It works directly on the compressed data, so there’s no re-encoding and no additional generation loss.

Highlights:

• Lossless transforms: rotate 90°/180°/270°, flip, and crop on MCU boundaries to avoid re-compression.
• Smart cropping: snap selections to the nearest safe boundary with an accurate preview of the final result.
• Size optimization: optimize Huffman tables and optionally convert between baseline and progressive layouts for smaller files with identical visual quality.
• Metadata control: view, preserve, or strip EXIF, IPTC, XMP, and ICC profiles; selectively keep key fields like GPS or orientation.
• Batch processing: apply consistent operations across large image sets.
• Integrity and analysis: validate JPEG structure and compare before/after sizes; confirm that no re-encoding occurred.
• Safe workflow: write to new files or in place with backups and undo.

Ideal for photographers, archivists, and web teams who need to rotate, trim, or tidy JPEGs and reduce file sizes—without sacrificing any quality.
