Convert and Resize Images
90
Convert images between JPG, PNG, WEBP formats. Resize and compress images for web or print.
JPG/JPEG: Best for photographs and images with many colors. Uses lossy compression, meaning some quality is lost to reduce file size. Perfect for web photos and social media. Does not support transparency.
PNG: Ideal for graphics, logos, and images requiring transparency. Uses lossless compression, preserving all image data. Larger file sizes than JPG but maintains perfect quality. Supports transparent backgrounds.
WEBP: Modern format developed by Google. Offers better compression than both JPG and PNG while maintaining quality. Supports both lossy and lossless compression, plus transparency. Excellent for websites but may not work in older browsers.
GIF: Limited to 256 colors. Best for simple animations and graphics. Not recommended for photos. Supports transparency but PNG is usually better for static images.
Use JPG when: Sharing photos on social media, emailing pictures, creating photo galleries, or when file size matters more than perfect quality.
Use PNG when: You need transparent backgrounds, working with logos or graphics, preserving text clarity, or when quality is more important than file size.
Use WEBP when: Optimizing images for modern websites, reducing page load times, or when you need both quality and small file sizes for web use.
Different formats serve different purposes. JPG is smaller and faster to load, making it ideal for websites and email. PNG preserves quality and supports transparency, perfect for logos and graphics. WEBP offers the best of both worlds for modern web applications. Converting ensures your images work best for their intended use.
Absolutely. This tool processes everything locally in your browser using JavaScript. Your images never get uploaded to any server—they stay on your device the entire time. We cannot see, access, or store your images. This approach ensures complete privacy and faster processing.
For most uses, 80-90% quality provides an excellent balance between file size and visual quality. Use 90-100% for professional photography or when quality is critical. Use 60-80% for web images where smaller file sizes improve loading speed. Experiment to find what works best for your specific needs.
Currently, this tool converts one image at a time to ensure the best performance and user experience. For batch conversion of many images, consider desktop software like IrfanView, XnConvert, or GIMP, which are designed for processing multiple files simultaneously.
