Large image files slow down websites and eat up storage space. Shrinkify offers a smart compression and photo optimization engine that balances visual quality with file size, helping you reduce image size efficiently.
Shrinkify is powered by WebAssembly (WASM). Unlike traditional websites that use JavaScript for everything, WASM allows us to run high-performance C++ and Rust code directly in your browser tab.
When you process an image, we spawn a Web Worker to handle the computation in a separate thread. This ensures that your browser UI remains smooth and responsive, even when compressing hundreds of images simultaneously.
*Metrics vary based on local hardware and browser version.
Select "Lossless" or a high quality setting (like 90%) in the settings menu. Converting PNG to WebP often reduces size significantly with zero perceptual loss.
Technically no. Since files are processed on your device, the only limit is your device's memory (RAM). We recommend batches of 50-100 files for smooth performance.
Currently, browser support for HEIC input varies. If your browser supports it, Shrinkify can convert it. We are working on a dedicated HEIC converter update.
WebP and AVIF provide superior compression compared to JPG and PNG. Switching usually results in 30-80% smaller file sizes with no perceptual quality loss, which is critical for Core Web Vitals and SEO.
Absolutely not. Shrinkify is a serverless frontend application. All logic runs in your browser via WebAssembly. Your data never touches any external server.
