How to Convert PNG to JPG Online Free
Convert PNG images to JPG to reduce file size. When to use each format and what quality to choose.
PNG vs JPG: When to Convert
PNG is lossless and supports transparency — ideal for logos, screenshots, and graphics with text. JPG uses lossy compression — ideal for photographs where file size matters more than pixel-perfect quality.
Convert PNG to JPG when: You have a photograph saved as PNG (unnecessarily large). You need to reduce file size for email or web upload. The image does not need transparency.
Do NOT convert when: The PNG has a transparent background you need to preserve. The PNG is a screenshot with text — JPG compression makes text look blurry.

Frequently asked questions
Does converting PNG to JPG reduce quality?
At 80%+ quality, the difference is invisible at normal viewing sizes. Only at 200% zoom do slight compression artefacts become visible.
Can I convert PNG to JPG if the PNG has a transparent background?
Transparent pixels will become white (or the colour you choose) when converting to JPG since JPG does not support transparency.
