Compress Images Online: Fast, Private & WASM-Powered (No Upload)
In today’s digital world, large images slow down websites and eat up storage. But why should you risk your privacy by uploading your personal photos to a cloud server? Our Compress Images tool uses cutting-edge WebAssembly (WASM) technology to optimize your images directly in your browser.
Experience lightning-fast image compression online with zero uploads, absolute privacy, and professional-grade quality.
Why Our WASM-Powered Image Compressor is Better
Most online compressors like TinyPNG or ILoveIMG require you to upload files to their servers. This is slow, has file size limits, and poses a privacy risk. Our tool is a client-side image optimizer that offers:
- Total Privacy: Your photos never leave your device. All processing happens in your browser’s memory.
- Blazing Speed: By using WASM (WebAssembly), we run high-performance image codecs (like MozJPEG and OxiPNG) at near-native speeds. No waiting for upload or download bars.
- No File Limits: Compress 10MB or 100MB images without “Premium” restrictions. Your only limit is your own computer’s RAM.
- Works Offline: Once the page is loaded, you can turn off your Wi-Fi and continue to shrink images perfectly.
High-Performance Compression for Every Format
1. JPG / JPEG Optimization
Our tool uses advanced algorithms to strip unnecessary metadata and optimize the Huffman table. You can reduce JPG file size by up to 80% while keeping the visual quality indistinguishable from the original.
2. PNG Compression (Lossless & Speed)
Stop struggling with “heavy” PNG files. We use optimized WASM-based compressors to prune color palettes and compress data streams, making your screenshots and graphics web-ready in milliseconds.
3. WebP: The Future of Web Images
Need even smaller files? Convert and compress WebP images for the best performance on modern browsers. Ideal for developers looking to boost their Google PageSpeed Insights score.
