Above 92 the file grows quickly with almost no visible gain.
JPEG cannot store transparency, so anything see-through is filled with this colour.
How to use this tool
Select the PNG, JPEG quality and background color. Replace the default white if it does not match the intended page, and compare compression artifacts on text or thin lines before choosing the final quality.
Results and examples
Inspect the filled background and edges in the JPEG at a useful zoom level. Even the highest quality setting is not lossless preservation of the PNG, so retain the original for future edits.
Worked example
Convert a transparent logo PNG at quality 88 over white to make a JPG with white formerly transparent areas. For a dark page, choose the page’s background colour and inspect the logo edge for a visible halo.
Limitations
- JPEG has no alpha channel, so the flattened background cannot be restored to transparency from this output alone.
- Lossy compression can blur small lettering and thin edges.

Frequently asked questions
Why did transparent areas turn white?
They were composited over the selected background before JPEG encoding.
Is quality 100 identical to PNG?
No. The format and encoder do not guarantee identical pixel preservation.
