Convert PNG images to JPG and shrink their file size. Add files, set quality, and download the results. Everything runs locally in your browser.

PNG is a lossless format that produces large files — a 3000×2000 pixel screenshot can weigh 5–15 MB. JPG uses lossy compression to create files that are 5–10× smaller with minimal visible quality loss. For photographs and images without transparency, JPG is the more practical format.
JPG is universally supported by every browser, email client, social media platform, and image editor. At quality 85–90, JPG produces visually identical results to PNG for photographic content while being dramatically smaller. Converting PNG screenshots and photos to JPG saves storage and makes files easier to share.
Note that JPG does not support transparency — transparent areas in your PNG will be filled with a solid background color (typically white). If you need transparency, keep your files as PNG or convert to WebP instead.
This converter processes files locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.
The conversion takes just a few seconds:
PNG-to-JPG conversion is useful in many real-world scenarios:
The ideal JPG quality setting depends on what you plan to do with the image:
This tool defaults to 85%, which covers the vast majority of use cases. You can adjust the slider at any time - even reconvert the same files with a different quality level.

PNG is lossless and therefore large for photographic content. JPG provides substantial savings:
Photo (PNG)
8.5 MB → 890 KB
Screenshot
1.2 MB → 320 KB
Social media graphic
2.4 MB → 450 KB
Savings are highest for photographs and images with smooth gradients. Graphics with large flat color areas compress less efficiently in JPG.
Core Web Vitals is a set of performance metrics Google uses when evaluating websites. One of them — LCP (Largest Contentful Paint) — measures the time until the largest visible element renders. On image-heavy pages, this is often a hero image or product photo.
Converting PNG photographs to JPG typically reduces file size by 5–10×, directly shortening download time and improving the LCP score. Combined with loading="lazy" and fetchpriority="high", this can significantly improve page performance.
For even smaller files, consider WebP (25–35% smaller than JPG) or AVIF (30–50% smaller). Use PageSpeed Insights to identify specific images worth optimizing.
