OptiDrop's Image Format Converter lets you convert images between JPG, PNG, WebP, and BMP formats directly in your browser. Whether you need to convert a PNG to JPG for a smaller file size, convert a JPG to PNG for transparency support, or convert any image to WebP for modern web optimization, this tool handles it all with zero uploads.

JPG vs PNG vs WebP — Which Format Should You Use?

JPG is the most universally compatible format, ideal for photographs and images with many colors. It uses lossy compression to achieve small file sizes. PNG is lossless, meaning no quality is lost during compression. It supports transparency, making it perfect for logos, icons, and images with sharp edges. WebP is the modern choice — it offers both lossy and lossless compression with significantly smaller file sizes than JPG or PNG. WebP is supported by all major browsers including Chrome, Firefox, Safari, and Edge.

Your converted image is ready to download instantly. The entire process happens locally in your browser — your images never leave your device, ensuring complete privacy for sensitive photos and documents.
