How In-Browser Image Compression Protects Your Privacy
Traditional online image compressors upload your files to external cloud servers where they are saved to disk, processed by backend software, and downloaded back. This introduces security and privacy risks when compressing sensitive company graphics, personal photographs, or identification documents.
Slifto executes the entire compression routine using your browser's hardware-accelerated CanvasRenderingContext2D. Pixels are drawn and re-encoded in your device's memory. No network bytes are transmitted, making the process instantaneous, unthrottled, and confidential.
