Convert PNG to SVG Online Wrap raster images in an SVG container for vector-compatible workflows.

The tool works by utilizing React's useState and useEffect hooks to manage the state of the uploaded image and generated SVG code. When an image file is dropped into the FileDropzone component, the handleFile function is triggered, which creates a new FileReader instance to read the file as a base64-encoded data URI using the readAsDataURL method. This data URL is then used to load an Image element, allowing the tool to determine the natural dimensions of the uploaded image. The width and height of the image are stored in the component's state using the setWidth and setHeight functions.

The tool generates an SVG XML string containing an image element with the xlink:href attribute set to the data URI, effectively wrapping the raster image in an SVG container. The viewport dimensions of the SVG element match the original image pixels, ensuring accurate rendering of the converted image. The generated SVG code is stored in the component's state using the setSvgCode function and can be downloaded as a file or copied to the clipboard. The use of URL.createObjectURL and Blob objects enables the tool to create a downloadable SVG file without requiring server-side processing. Additionally, the FileReader and Image elements are used in conjunction with React's hooks to manage the conversion process efficiently.

The conversion process involves using browser APIs such as URL.revokeObjectURL to revoke the object URL when the image is reset or removed, ensuring that system resources are released properly. The tool also utilizes React's useCallback hook to memoize functions like handleFile and downloadSvg, preventing unnecessary re-renders and improving performance. The generated SVG code includes attributes such as width, height, and viewBox, which are set based on the original image dimensions, allowing for accurate rendering of the converted raster image in various contexts. Overall, the tool's implementation relies on a combination of React hooks, browser APIs, and standard web technologies to achieve efficient and accurate conversion of PNG images to SVG format.
