What is a PNG File?
PNG (Portable Network Graphics) is a lossless image format that supports full transparency via an alpha channel. Unlike JPG, PNG does not degrade in quality each time it is saved, making it ideal for logos, graphics, screenshots, and any image that needs a transparent background. PNG files are larger than JPG at equivalent visual quality, which is why converting to WebP or JPG is common for web use.
When to Convert PNG to JPG
Convert PNG to JPG when file size matters more than transparency. JPG is 40-80% smaller than PNG for photographs. It is the preferred format for sharing photos via email, WhatsApp, or social media.
Important: Set background color before converting
JPG does not support transparency. Expand Advanced Options and choose a background color (default white) to replace transparent areas.
When to Convert PNG to WebP
WebP is the modern replacement for both PNG and JPG on the web. It supports transparency like PNG but is 25-35% smaller. All major browsers support WebP as of 2026. Convert PNG to WebP to improve Core Web Vitals scores and page load speed without sacrificing image quality.

Frequently Asked Questions
How do I convert PNG to JPG without losing quality?
Set the quality slider to 90-95%. JPG is lossy so some information is always lost, but at high quality settings the difference is invisible to the human eye. For pixel-perfect output, convert to WebP at 100% quality instead.
Why does my PNG have a black background after converting to JPG?
JPG has no transparency support. Your PNG's transparent pixels must be filled with a color. Open Advanced Options and change the Background Color from the default to white (#FFFFFF) or any color before converting.
Does converting PNG to WebP reduce quality?
At quality 80-90%, WebP is 25-35% smaller than PNG with barely visible quality difference for photos. For pixel-perfect graphics, convert at 100% for lossless WebP.
Can I convert multiple PNG files at once?
Yes. Drop multiple PNG files onto the tool or select them all in the file picker. All will be converted with the same settings and can be downloaded as a ZIP.
Is PNG better than JPG for website images?
It depends on the image. PNG is better for logos, icons, screenshots, and graphics with sharp edges or transparency. JPG is better for photographs where transparency is not needed. WebP is the best choice for both in modern browsers.
