About JPG to PNG
Convert JPG photos into lossless PNG files for editing workflows and broad compatibility.
PNG will not restore detail already removed by JPG compression, but it avoids adding more lossy artifacts during later edits and supports transparent pixels in future work.

How to use JPG to PNG
- Choose the source files in a supported format (JPG or JPEG input, PNG download) and confirm the displayed file details.
- Prepare the available controls for this practical goal: Open an image in software that requires PNG
- Run JPG to PNG and confirm that the new result matches the stated outcome before saving it.
- Check this known constraint before download: PNG cannot restore detail removed by earlier JPG compression If needed, revise the settings and create another version from the retained source.

JPG vs PNG
JPG uses lossy compression and is usually efficient for photographs. PNG uses lossless compression, preserves sharp graphic edges and supports transparent pixels.
Converting a JPG to PNG prevents another lossy save, but it does not improve the quality of the original JPG or make its existing background transparent.
Important limitations
- PNG cannot restore detail removed by earlier JPG compression
- The PNG result is often larger than the JPG source
Troubleshooting JPG to PNG
The result is different from what you expected
