PNG WebP Free Converter
The PNG → WebP Tool
Convert PNG images to WebP right in your browser. Drag & drop files or select them below.
Tip: 80–85 is a good starting point for photos; try higher for icons/graphics. Browser canvas encodes lossy WebP; for true lossless use a server-side tool (e.g., Sharp).
How the PNG to WebP Converter Works
The PNG to WebP Converter is a simple browser-based tool that lets you compress and convert PNG images into the newer, faster WebP format. It works entirely on your device — no files are uploaded or stored on any server — which means your images stay completely private and secure.
When you drag and drop a PNG file or select one from your computer, the converter uses your browser’s built-in image processing features to read and redraw the image on a hidden digital canvas. Then, it re-encodes that image as a WebP file. WebP is a modern image format developed by Google that provides both lossless and lossy compression. In practice, WebP files are usually 25–35% smaller than comparable PNGs without noticeable loss in quality.
The quality slider lets you choose how aggressively to compress the image. A setting of 80–85 is ideal for photos, balancing sharpness and size, while higher values (90–100) are better for icons or images that need to stay pixel-perfect. Lower values produce smaller files for faster loading, especially useful for websites and mobile apps.
Once the conversion is complete, the tool automatically downloads the new .webp file and displays how much space was saved. You can also preview or batch-convert multiple images at once.
Because all the work happens locally in your browser, it’s instant, safe, and doesn’t require any technical setup. Whether you’re a web developer optimizing images for a faster site or simply want to save storage space, this converter provides a quick, private, and reliable way to switch from PNG to WebP in seconds.
