Frequently Asked Questions

No, never. Our bulk image compressor is built using advanced HTML5 Client-Side technology. This means all the compression and format conversion (like JPEG to WebP) happens entirely inside your own web browser. Your private photos never leave your device, ensuring 100% security and privacy.
WebP is a modern image format developed by Google that provides superior lossless and lossy compression for images on the web. Using WebP allows webmasters and developers to create smaller, richer images that make the web faster. It can reduce file sizes by up to 34% compared to standard JPEGs while maintaining the same visual quality.
Because the tool processes files locally using your device’s memory (RAM), there is no hard server limit. However, for the best and most stable performance without crashing your browser tab, we recommend dropping batches of 20 to 50 images at a time, depending on their original file sizes.
It depends on the compression level you set. At the default 80% quality level, the visual difference is virtually undetectable to the human eye, but the file size reduction is massive. If you need absolute pristine quality for photography portfolios, you can set the slider to 95-100%.
