JPG and PNG are both popular image formats, but they serve different purposes:
| Format | Compression | Transparency | Best For | File Size |
|---|---|---|---|---|
| JPG | Lossy | ✗ Not supported | Photographs and web images | Smaller |
| PNG | Lossless | ✓ Supports | Graphics with text or transparency needs | Larger |
Converting JPG to PNG preserves image quality completely while adding transparency support, making it ideal for graphics, logos, and images that need to be edited further.
PNG format uses lossless compression, so quality is always preserved at 100%. The quality slider is shown for UI consistency but doesn't affect PNG output:
| Quality Setting | PNG Output | Note |
|---|---|---|
| 100% (Lossless) | Perfect quality preservation | PNG's default lossless compression |
| Any Setting (10-99%) | Still lossless quality | Quality parameter ignored for PNG |
| UI Consistency | Same interface as JPG converter | For familiar user experience |
