01 — Why this tool?

Convert PNG to JPG…

PNG uses lossless compression, making it ideal for logos, icons, and any visual that needs sharp edges and transparency. But that quality comes at a cost: for a real photo taken with a smartphone or camera, a PNG can easily weigh 5 to 10 times more than an equivalent JPG. JPG applies destructive compression optimized for photography: it analyzes areas where the human eye is least sensitive to loss and discards information there, producing ultra-compact files while preserving a virtually identical visual result for most photos. Converting PNG to JPG is therefore especially valuable for photos (not graphics with transparency) that you want to share, publish on a site, or send by email. The only thing to keep in mind: JPG does not support transparency, so any transparent area in the original PNG will automatically be replaced by a white background during conversion.

05 — Frequently asked questions

Everything that deserves a clear answer.

    Will I lose transparency from my PNG?+

    Yes, JPG format does not support transparency. Transparent areas will turn white. To keep transparency, consider using WebP format.

    Does conversion reduce quality significantly?+

    The change is barely visible to the human eye for photos, but the file size reduction is huge. For simple graphics (logos), PNG remains better.

    Is it secure?+

    Yes, PixFlow works in 'Client-Side' mode. Your files are converted by your own computer, nothing is sent to the internet.

    Can I convert screenshots?+

    Absolutely, it's the ideal use case. Screenshots are often heavy PNGs that benefit greatly from being converted to JPG.
