Frequently Asked Questions
Why is local browser-based compression safer?
With local compression, your image data is processed directly inside your browser's memory using JavaScript and WebAssembly. Since there is no server upload, your sensitive photos can never be leaked, cached, or intercepted by third parties.
Can I compress images without internet on Nexifr?
Yes. Once the page is loaded, the Image Compressor is fully functional without any network connection because all assets and code run locally.
