When to use this tool
Adjust quality to reduce photo bytes while keeping pixel dimensions. This tool exports JPEG; use the separate target-size tool when you need a specific KB limit.
File workflow example
This illustrates the expected operation. Actual file size, quality and recognition depend on your source and settings; inspect the result in the tool.
Example input
1200 × 800 px · PNG
Example result

How to read and check the result
A same-size PNG becomes JPEG with white replacing transparency. Quality 80 does not mean 80% of original quality or 20% fewer bytes. Zoom in on small text and edges.
