Tips for Converting PNG to JPEG
- Transparent pixels are filled with white. Edit the PNG first if you need a different background colour.
- Quality 85–90 is visually indistinguishable from lossless PNG for photographs and reduces file size by 80%+.
- PNG logos, screenshots, and line art with sharp edges may show subtle ringing artefacts around high-contrast boundaries at lower quality settings.

Why Convert PNG to JPEG?
People convert PNG to JPEG to significantly reduce file size — JPEG photos are typically 5–10× smaller than lossless PNG.
JPEG (developed by Joint Photographic Experts Group in 1992) is the required format for many platforms — stock photo sites, email, and social networks. If your PNG contains a photograph rather than a logo or screenshot, converting to JPEG loses very little visible quality at high quality settings while dramatically reducing file size and bandwidth usage.
