Introduction
Some design and document workflows ask for PNG even when the available source is a JPEG. JPG to PNG creates a genuine PNG derivative for that handoff. It does not turn a photograph into vector artwork or restore detail lost during earlier JPEG compression.

What This Tool Does
SavDown decodes the JPEG, applies EXIF orientation and encodes PNG with compression level 8. This prevents an additional lossy JPEG export, but the decoded source pixels still contain any original blur or compression artifacts. A larger output is common for photographs.
