How the Browser-Based Conversion Works

Each conversion uses the Canvas API built into your browser. The tool draws your source image onto an offscreen canvas and exports it in the chosen target format using the browser's native encoding engine. No file reaches any external server at any point in this process.

Quality controls for JPG and WebP output let you balance file size against visual fidelity on a scale from 10 to 100. PNG output is always lossless. The converted file downloads directly to your device.

When to Use Each Format

JPG compresses photographic content efficiently and remains the standard format for most web images and camera outputs. PNG preserves transparency and renders text and flat graphics without compression artifacts, making it the correct choice for logos, screenshots, and graphics with sharp edges.

WebP delivers smaller file sizes than both JPG and PNG at equivalent visual quality. Major browsers support WebP fully. Converting existing JPG or PNG assets to WebP reduces page load weight without a visible quality trade-off for most photographic content.
