Free Online Image Converter — Convert PNG, JPG, WebP, BMP in Browser

Convert PNG to JPG, WebP, BMP & Vice Versa. Convert photos between PNG, JPG, WebP, GIF, and BMP formats with instant browser-based rasterization.

What is Converter and what does it do?

The Image Converter is a versatile online tool that converts photos and graphics between all major web image formats — including PNG, JPG, JPEG, WebP, and BMP — with zero installation and zero cloud uploads. It enables seamless format switching to optimize file size, ensure software compatibility, or handle transparency.

Operating completely client-side, the converter processes image rasterization directly within your browser's execution engine. You get instant conversion speeds, full privacy for confidential photos, and the freedom to convert as many files as you need without limits.

  • Convert images between PNG, JPG, WebP, and BMP formats instantly in your browser.
  • Convert transparent PNG graphics to JPG with customizable solid background colors.
  • Transform heavy JPG and PNG photos into modern, lightweight WebP format.
  • Batch convert multiple images with individual or bundled downloads.
  • Preserve original image resolution and visual fidelity during format transcoding.

How does Converter work?

When an image is loaded, the browser's native decoder pipeline parses the raw image bitstream into an ImageBitmap or HTMLCanvasElement. The pixel buffer is rendered onto an off-screen canvas while preserving original color gamuts and channel depths.

The canvas invokes native browser encoding engines (`canvas.toDataURL()` or `canvas.toBlob()`) targeting the chosen output MIME type. Transcoded bytes are packaged into a downloadable file blob in memory with zero network requests.

100% private: all processing happens locally in your browser using client-side WebAssembly, HTML5 Canvas, and modern Web APIs. Your files are never uploaded to any server.
