Largest Contentful Paint (LCP) is a critical user experience metric that Google uses to evaluate how fast your site renders. Large, unoptimized images are the single most common cause of poor LCP scores.
By using OptiConvert to compress and convert your files to modern formats like WebP before uploading, you significantly decrease your page weight, resulting in faster load times and higher SEO search visibility.
OptiConvert runs completely in your web browser. All file reading, formats conversion, background erasure, and adjustments are calculated locally using HTML5 canvas context and JavaScript FileReader APIs.
Because there is zero server-side uploading, your private photographs and business graphics are 100% secure. You also get instant rendering speeds without waiting for network transfers.
No. All conversions, compression, background removal, and edits occur directly in your browser. Your images never leave your computer, ensuring 100% privacy and security.
OptiConvert uses high-performance canvas pixel scanning. It auto-detects background colors at the corners or matches colors selected using the Eyedropper tool. You can adjust the tolerance slider to remove shadows and gradients.
Standard PNG files support millions of colors. Color Quantization reduces the image colors to 256 indexed colors (8-bit) using color space mapping. This shrinks PNG sizes by 50% to 75% while fully preserving alpha transparency.
