Convert a 2MB website PNG graphic to WebP.
WebP uses modern compression algorithms that outperform older PNG encoding for web use.
Solution: JPEG does not support transparency. If you need a transparent background, choose PNG or WebP as your target format.
MWT Labs tools are built using modern web primitives—including WebAssembly, Web Workers, and native HTML5 Canvas / Cryptography APIs. When you process images, parse PDF documents, format JSON payloads, or calculate financial schedules, execution happens strictly within your local browser memory sandbox.
You can convert images between WebP, JPEG, PNG, and standard browser-supported image formats quickly and cleanly.
No. The format conversion executes entirely inside your browser's local memory. Your images are never transmitted across the network or stored in the cloud.
WebP is ideal for modern websites because it provides 25% to 35% smaller file sizes than JPEG or PNG while preserving high visual quality and supporting transparency.
Yes. JPEG does not support transparent backgrounds and will fill transparent areas with a solid background color (typically white). Use WebP or PNG if you need transparency.
Yes. You can upload multiple image files to convert and download them individually or bundled together for convenience.
