JPG to PNG Converter

JPG and PNG serve different needs. JPG is best for photos — it uses lossy compression that's excellent for natural images. PNG is best for graphics, screenshots, and any image that needs transparency or perfect pixel reproduction. Sometimes you have a JPG and need a PNG, typically because a downstream tool requires it, or because you plan to edit the image and don't want repeated JPG generations to degrade quality.

This converter takes any JPG and re-encodes it as PNG using the browser's Canvas API. The output is pixel-perfect (PNG is lossless) and the result will not degrade further if re-edited or recompressed. Note that the file size will almost always be larger — JPG is much more efficient for photographic content. Use this when you specifically need the PNG format; don't use it to 'improve quality' (the JPG already discarded that data, converting can't bring it back). Runs entirely in your browser.
