📷

JPG — Best for Photos

The universal format. Perfect for photographs, social media, and email. Lossy compression keeps files small. Widely supported everywhere.

🖼️

PNG — Best for Transparency

Use PNG when you need a transparent background or when pixel-perfect quality matters. Lossless compression — larger files but zero quality loss.

🌐

WebP — Best for Web

Google's modern web format. 25–35% smaller than JPG at equivalent quality. Supported in all modern browsers. Ideal for websites and apps.

⚡

AVIF — Best Compression

The newest and smallest format. Up to 50% smaller than JPG. Excellent for web performance. Browser support is growing rapidly in 2024+.

Frequently Asked Questions

Is the image format converter really free?

Yes, completely free. No sign-up, no watermark, no limits. Convert as many images as you need directly in your browser.

What formats can I convert between?

You can convert JPG, JPEG, PNG, WebP, GIF, and BMP to JPG, PNG, WebP, or AVIF. WebP and AVIF give the best compression for web use.

Does my image get uploaded to a server?

No. All conversion happens in your browser using the Canvas API and WebAssembly. Your images never leave your device.

What quality setting should I use?
