Exports a JPEG as PNG; it does not restore detail removed by the JPEG’s previous lossy compression.

How to use this tool
Select the photo and proceed knowing this changes the format rather than adding transparency.
Results and examples
Compare PNG size and color rendering to ensure increased storage is acceptable for later editing.
Worked example
Convert an emailed JPEG chart to PNG for an editor and check the legibility of its smallest numbers at the intended display size.
Limitations
- Existing JPEG artifacts remain in the PNG; this is not a sharpness-restoration operation.
- Changing the image format does not remove its background or create transparency around a subject.
Data handling
Processing stays in the current browser tab; the site does not upload tool input for the calculation itself.

Frequently asked questions
Does PNG make the background transparent?
No. Existing background pixels remain unless you remove them with a separate editing tool.
What should I inspect in a document image?
Compare small lettering for the same compression blocks and ringing visible in the JPEG source.
