How It Works
This JPG to PNG converter uses the HTML5 Canvas API to transform your JPEG images into PNG format entirely within your browser. When you upload or drag a JPG file, the tool loads it onto an invisible canvas element and then exports it as a PNG image.
PNG (Portable Network Graphics) is a lossless image format that supports transparency. Converting from JPG to PNG is useful when you need to preserve image quality for further editing, add transparency layers, or use an image in contexts where lossless quality is required.
Because JPG is a lossy format and PNG is lossless, the converted PNG file will typically be larger than the original JPG. The file size comparison shown after conversion helps you understand the size trade-off between formats.
Your images never leave your device. The entire conversion process runs locally in your web browser using JavaScript and the Canvas API. No files are uploaded to any server, ensuring complete privacy for your images.
