Online Image Format Converter — JPG, PNG, WebP, BMP

This free image converter lets you change image formats directly in your browser using the HTML5 Canvas API. No file is uploaded to any server — all processing happens locally on your device, keeping your images completely private.

When to Use Each Format

• JPG (JPEG) — best for photographs and images with many colors. Uses lossy compression for smaller file sizes. Ideal for web images and email attachments.
• PNG — lossless format supporting transparency. Best for logos, icons, screenshots, and graphics that need sharp edges and transparent backgrounds.
• WebP — modern format by Google offering superior compression for both lossy and lossless images. Up to 30% smaller than JPG/PNG with similar quality. Supported in all modern browsers.
• BMP — uncompressed bitmap format. Large file sizes but perfect pixel quality. Used in Windows applications and when lossless raw data is needed.

JPG vs PNG — Which to Use?

Use JPG for photos and images with gradients. Use PNG when you need transparency or sharp text/lines. Use WebP for the best of both worlds on modern websites.
