Absolutely not. This tool is entirely 100% browser-based. Your JPG images are compressed locally inside your web browser using your device’s own processing power. They are never uploaded, transmitted, or stored on any server, keeping your data completely private.

When you select your JPG files, a local JavaScript script handles the compression and converts them into WebP format instantly. Since the entire process happens offline inside your browser tab, it is incredibly fast, secure, and doesn’t consume your internet bandwidth for file uploads.

WebP is a modern image format that provides superior lossy and lossless compression. Converting your JPGs to WebP reduces file sizes by up to 30% or more without any noticeable loss in quality, which helps websites load much faster and saves storage space.

Since this tool doesn’t rely on server limits, there are no daily restrictions or rigid file size caps. You can batch-compress as many JPG images as you need. The performance is only limited by your device’s RAM and processing capabilities.
