Bulk Compressor — No Uploads Required
Our Bulk Compressor is designed for high-volume workflows. Instead of processing images one by one, you can drop dozens of files into the tool, set a global quality target, and let our multi-threaded engine optimize them all simultaneously. Once finished, download all your optimized images in a single, well-organized ZIP archive. Like all Imgira tools, processing is 100% local and private.
