Image compression reduces file size by eliminating redundant pixel data, either losslessly (preserving every detail) or lossily (discarding imperceptible information). The JPEG standard, introduced by the Joint Photographic Experts Group in 1992, uses Discrete Cosine Transform (DCT) to achieve lossy compression with adjustable quality levels. PNG, released in 1996, uses lossless LZ77 compression and supports transparency - making it preferred for logos and UI elements. WebP, developed by Google in 2010, offers 25-34% smaller file sizes than JPEG at equivalent quality and is now supported by all major browsers including Chrome, Safari, and Firefox.
India's average mobile internet speed stood at approximately 24 Mbps in 2024 according to Ookla's Speedtest data - significantly lower than South Korea or UAE. With over 75% of Indian internet usage happening on mobile devices, large unoptimised images are the single largest contributor to slow page load times. Google's Core Web Vitals, which directly influence search rankings on Google India, penalise pages with poor Largest Contentful Paint (LCP) scores - often caused by heavy hero images. E-commerce sellers on platforms like Flipkart, Meesho, and Amazon India must also meet strict product image size limits.
This compressor runs entirely in your browser using the HTML5 Canvas API. Your images are never uploaded to any server, ensuring complete privacy - important for businesses handling sensitive product photos, documents, or confidential graphics. Adjust the quality slider to balance file size and visual fidelity before downloading the optimised image.
