JPG to PNG Converter
Free JPG to PNG converter. Change JPG photos into PNG format in seconds, right in your browser. Private, fast, no signup or watermarks needed.
About this tool
Some tools, editors and upload forms insist on PNG format. This free converter turns any JPG into a PNG in one click, with zero fuss.
As always, the conversion happens entirely in your browser. Your images are never uploaded, so your files never leave your device. No accounts, no watermarks, no limits.
How to use
Choose a JPG image and click Convert to PNG. The tool redraws it as a PNG at full resolution and hands you a download link instantly.
Keep in mind that converting JPG to PNG does not improve quality. JPEG artifacts already baked into the photo stay exactly as they are. Convert for compatibility with tools that need PNG, not for better looks.
The math behind it
JPEG stores images with lossy compression, discarding fine detail to save space. PNG stores images losslessly, keeping every pixel exactly. Converting means decoding the JPEG back to raw pixels and re-encoding them in PNG's exact format.
Because no new detail can appear from a JPEG source, the PNG is a pixel-perfect copy of the JPG you started with, just stored differently. The file usually gets bigger, since lossless storage of photographic detail takes more space than JPEG's clever shortcuts.
