JPG to PNG

Convert JPEG images to PNG format directly in the browser. PNG is a lossless format ideal for graphics, logos, and images that require transparency.

Converting JPG to PNG does not improve image quality — PNG is lossless, but cannot recover detail already lost in the JPEG compression. Use it when you need a format that supports transparency or when a tool requires PNG input.

Frequently Asked Questions

Will JPG to PNG conversion improve quality?

PNG is lossless, but the conversion cannot recover quality already lost in the original JPEG. It's useful for workflow compatibility, not quality improvement.

Does PNG support transparency?

Yes. PNG supports full alpha channel transparency, which is why it's preferred for logos and UI graphics.

Will the file size increase?

Yes. PNG files are typically 2–5× larger than equivalent JPEGs because PNG uses lossless compression. Consider using WebP if you need both smaller size and quality.

Is processing done on a server?

No. The conversion runs entirely in your browser using the Canvas API. Your images are never uploaded or transmitted anywhere.
