Convert JPG to PNG online free. Instant browser-based conversion with no quality loss. Supports batch conversion. No upload to server — your images stay private on your device.
JPG and PNG are the two most common image formats but they serve different purposes. JPG uses lossy compression which reduces file size but can reduce quality. PNG uses lossless compression which preserves every pixel perfectly — making it ideal for logos, screenshots, graphics with text, and images that need transparent backgrounds.
Our free JPG to PNG converter runs entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server — conversion happens instantly on your own device. This means your private photos and confidential documents stay completely private.
Convert JPG to PNG when you need a transparent background, when you want to edit an image multiple times without losing quality, when you are working with logos or graphics with sharp edges, or when you need to embed images in documents that require lossless quality.
