When this tool is useful
Photographs, scans, and screenshots that do not need transparent pixels or pixel-perfect edges.
How local processing works
PNG pixels are decoded locally, composited onto a fixed white background, then encoded as JPEG at the selected quality.
How to use it
- Choose the source files.
- Review the available settings and page order.
- Process locally, inspect the result, and download it.
Important limitations
Logos, text-heavy graphics, and transparency can look worse in JPEG. PNG may remain the better choice for those assets.
