About PNG to JPG/JPEG
PNG keeps every pixel with alpha support, which makes files large. JPG encodes the same picture with lossy compression and no alpha channel, so photos shrink while transparency is lost. Flatten transparent areas onto a white or matching background before converting, since JPG cannot store alpha. Set the quality slider near 85 for sharing, higher for prints. Text and line art soften under quantization, so keep the PNG master for graphics and export a fresh copy whenever settings change.
Why convert PNG to JPG/JPEG?
- Smaller files with JPG/JPEG lossy compression.
- Keep quality where supported.
- Private, no upload - runs in your browser.
PNG vs JPG/JPEG
| Animation | No | No |
|---|---|---|
| Transparency | Yes | No |
| Compression | lossless | lossy |
| Typical use | PNG stores lossless images with transparency support. | JPG is the same JPEG codec under the three-letter extension from DOS-era naming. |
When not to convert PNG to JPG/JPEG
- Skip JPG/JPEG for archival masters: lossy compression discards detail, so keep the PNG original.
- Flatten transparency first: JPG/JPEG has no alpha channel, so composite PNG over a background color.
Limits
Starting point: PNG - Lossless graphics with transparency support. Lossless quality means larger files than JPEG. No transparency support, so alpha channels are dropped. Set the quality slider near 80-90 for JPG/JPEG photos from PNG, and keep dimensions matched to the source.
