Convert image formats
instantly in your browser.

Every image format has trade-offs. JPG is universally supported and ideal for photographs, but it uses lossy compression — every save degrades quality slightly. PNG preserves every pixel with lossless compression, which makes it perfect for screenshots, logos, and graphics with text, but files tend to be large. WebP, developed by Google, combines the best of both: it produces files 25–35% smaller than JPG at equivalent visual quality and supports transparency like PNG.

Choosing the right format depends on where the image will be used. A product photo on an e-commerce site benefits from WebP's smaller file size, which means faster page loads and better Core Web Vitals scores. A logo destined for print or a design file should stay as PNG to avoid compression artifacts. And if you're emailing images to someone who might open them on an older device, JPG remains the safest choice for compatibility.

When to use each format

• JPG — Best for photographs, social media uploads, and email attachments. Universally supported on every device and platform.
• PNG — Best for screenshots, logos, icons, and any image with text or sharp edges. Lossless, so no quality loss, but larger files.
• WebP — Best for websites and web apps. Smaller than JPG with better quality. Supported by all modern browsers since 2020.

How browser-based conversion works

This tool uses the HTML5 Canvas API to decode your image and re-encode it in the target format. When you convert PNG to WebP, for example, the browser reads the PNG pixels into a canvas element, then exports them as a WebP file using the canvas.toBlob() method. The quality slider controls the compression ratio for lossy formats (JPG and WebP). At 100%, you get near-lossless output; at 80%, you get a good balance of quality and file size.

Because selected-file conversion happens in your browser, there are no file-size limits imposed by a processing server, no processing upload queues, and no server-side retention of selected files by the tool. The selected image bytes remain in the browser during conversion; disclosed hosting, consent, analytics, and advertising services can make separate requests. This distinction is especially important for sensitive documents, client photos, or proprietary design assets.
