About Image Converter
Our Image Converter is a powerful, browser-based tool that transforms your images into modern, web-optimized formats like WebP and AVIF. These next-generation formats provide significantly better compression than traditional JPEG and PNG, often reducing file sizes by 50-80% while maintaining or even improving visual quality. This makes your websites load faster, reduces bandwidth costs, and improves user experience across all devices.
Built with the latest web technologies, our converter runs entirely in your browser using the HTML5 Canvas API and modern JavaScript. This means your images never leave your device - they're processed locally, ensuring complete privacy and security. The tool supports batch processing, allowing you to convert dozens of images simultaneously with consistent quality settings, saving you valuable time in your workflow.
Whether you're a web developer optimizing site performance, a blogger preparing images for publication, or a business owner reducing storage costs, our Image Converter provides professional-grade results with an intuitive interface. The tool also includes intelligent resizing options that maintain aspect ratios and prevent image distortion.

Frequently Asked Questions
What are WebP and AVIF formats?
WebP and AVIF are modern image formats that provide superior compression compared to JPEG and PNG. WebP typically reduces file sizes by 25-50% while AVIF can achieve 50-80% smaller files with the same or better visual quality. Both formats are supported by all modern browsers.
Are my images uploaded to your servers?
No, all image processing happens entirely in your browser using HTML5 Canvas and JavaScript. Your images are never uploaded, transmitted, or stored on our servers. This ensures complete privacy and security for your files.
What's the maximum file size supported?
The tool can handle images up to several hundred megabytes, limited primarily by your device's available memory. For optimal performance, we recommend images under 50MB. Very large images may take longer to process.
Which quality setting should I use?
For most web use, 80-85% quality provides excellent results with significant size savings. For photography or detailed images, try 90-95%. For thumbnails or less critical images, 60-75% can dramatically reduce file sizes with acceptable quality.
Can I convert images back to JPEG or PNG?
Yes, our tool supports conversion to traditional formats as well. You can convert WebP or AVIF files back to JPEG or PNG if needed for compatibility with older systems or specific use cases.
Does resizing reduce image quality?
Our tool uses high-quality resampling algorithms that preserve as much detail as possible. When downsizing images, quality is generally well-preserved. The "maintain aspect ratio" option prevents distortion by automatically adjusting dimensions proportionally.
Why should I use WebP over JPEG?
WebP provides 25-50% better compression than JPEG while maintaining similar visual quality. It supports both lossy and lossless compression, transparency (like PNG), and animation (like GIF). All modern browsers support WebP, making it ideal for web optimization.
Can I process RAW camera files?
Currently, the tool supports standard web image formats (JPEG, PNG, GIF, WebP, etc.) but not RAW camera formats like CR2, NEF, or ARW. You'll need to export RAW files to JPEG or TIFF first using photo editing software.
