About this tool
About this tool
JPG to PNG Converter decodes a JPEG image and re-encodes it as PNG using the browser canvas. PNG is lossless, so the output preserves the decoded pixels at full quality and supports transparency for future editing. All processing happens locally in your browser.
Re-encode JPG photos as lossless PNG images without uploading them. PNG keeps every pixel exactly as decoded, which makes it the preferred format for further editing, graphics work, and any project that needs a transparent background layer.
