Legacy compression sites like Optimizilla and CompressJPEG were built over a decade ago. Every single photo has to travel across your internet connection to an external server. Shrinkify uses modern multi-threaded WebAssembly to optimize photos directly using your computer's own processor.
If you have 100 vacation photos or product catalog shots, Optimizilla forces you to upload them in 5 separate batches. On Shrinkify, you select all 100 photos at once and download a single tidy ZIP in seconds.
