This free image format converter changes an image between JPG, PNG, and WebP entirely in your browser. Select the target format, click Convert, and a side-by-side before-and-after comparison shows the result along with the new file size — so you can see exactly how much space the new format saves before downloading. WebP consistently delivers 25–35% smaller files than equivalent JPG at the same visual quality, making it the best choice for images destined for modern websites.
Upload any JPG, PNG, or WebP image, choose your output format, and click Convert. The conversion runs entirely inside your browser using the HTML5 Canvas API — no file is ever sent to a server. Once conversion is complete, a side-by-side preview shows the original and converted image along with both file sizes, so you can confirm the result before downloading.
Use WebP for any image served on a website. WebP produces files 25–35% smaller than equivalent JPG at the same visual quality. All modern browsers support it and the file size reduction directly improves page load speed and Core Web Vitals scores. Converting JPG to WebP is the single easiest performance improvement for most websites.
Use PNG when you need a transparent background, pixel-perfect sharpness, or lossless reproduction of screenshots, logos, and diagrams. PNG uses lossless compression so no quality is lost, but file sizes are larger than JPG or WebP for photographs.
Use JPG for photographs being shared via email or on platforms that don't support WebP. JPG is universally supported and produces small files for photographs, but uses lossy compression and doesn't support transparency. Converting WebP to JPG takes a single click when platform compatibility is required.
No — converting from JPG to PNG won't recover quality lost during the original JPG compression. It will produce a larger lossless file, but the underlying quality stays the same. Convert to PNG before compressing, not after.
Yes. All conversion happens inside your browser using the Canvas API. Your images are never uploaded to any server, making this one of the most private image converters available.
JPG does not support transparency. When you convert a PNG with a transparent background to JPG, the transparent areas become white. Use WebP if you need both small file size and transparency support.
Nothing — they are the same format. JPEG is the full name (Joint Photographic Experts Group) and JPG is the shortened file extension used on Windows systems. Both refer to the same lossy compression format.
Upload your WebP file above, select JPG as the output format, and click Convert. The download will be a standard .jpg file compatible with all platforms and email clients.
WebP is more efficient than JPG for photographs but can sometimes produce larger files than PNG for simple graphics with large flat areas of colour, like logos or icons. In those cases, keep the PNG.
