Quick Guide: Which format should I choose?

• WebP (Recommended): The modern web standard. Offers incredible compression and supports transparent backgrounds. Replaces both JPG and PNG.
• AVIF: The next-generation format. Produces even smaller file sizes than WebP for lightning-fast websites.
• JPG: The classic choice for standard photographs. Highly compatible but doesn't support transparency.
• PNG: Perfect for flat graphics, logos, or icons that need transparency. (Note: Because it is lossless, PNG files are much larger).

Pro Tips for Best Results

Use WebP or AVIF to get the absolute smallest file sizes for your websites.
Converting JPG to PNG? Your file size will increase because PNGs hold uncompressed pixel data. Use WebP instead to keep the size small!
Total Privacy: Because this tool runs locally in your browser, it is 100% safe for confidential commercial use, NDAs, and private photos.
Check the Badges: Our tool shows you exactly how much file size you saved (in green) after every conversion.
