What is JPG to PNG Converter?
A JPG to PNG converter transforms JPEG images into PNG format.
Unlike JPEG, PNG uses lossless compression — meaning no image data is lost during the conversion. PNG also supports transparency (alpha channel), which JPEG does not. This makes PNG ideal for logos, graphics, screenshots, and images that need crisp edges or transparent backgrounds. This free online converter processes everything in your browser using the Canvas API — your images are never uploaded to any server, making it completely private and fast. It handles batch processing, so you can convert dozens of images at once by dragging and dropping. An optional transparency feature lets you pick a specific color (like white or green) and make all pixels of that color transparent in the output PNG, which is useful for quick background removal.
