JPEGmini

JPEGmini — Free Download. JPEG image compression
JPEGmini is a patented photo recompression technology that significantly reduces image size without affecting their perceptual quality. The technology operates in the baseline JPEG domain, producing files that are fully compatible with any browser, photo software, or device that supports the standard JPEG format.

  • Smart compression. The technology analyzes each image to determine the optimal level of compression possible without perceptible visual degradation. The compression engine identifies and preserves critical details while eliminating data redundancies that do not contribute to the visual experience.
  • Metadata preservation. All EXIF metadata, copyright information, and color profiles are kept intact during the compression process. This feature ensures that the image's technical information remains available for photo management systems.
  • Batch processing. Allows processing multiple images simultaneously with uniform or customized settings. The feature supports drag-and-drop to streamline workflow in high-volume photographic productions.
  • Photoshop integration. Includes a plugin for Adobe Photoshop that allows compressing images directly from the software interface. The integration works as an export filter that maintains all native editing capabilities.
  • Visual comparison. Side-by-side comparison tool showing the original and compressed image with reduction percentage indicators. The display allows toggling between both versions to evaluate results in detail.
  • Custom settings. Advanced options to configure specific compression parameters based on quality or file size requirements. The controls allow setting size limits and adjusting predefined profiles for different uses.
  • Folder monitoring. Automatic folder watch function that processes new images added to specific directories. This automation facilitates continuous workflows in photographic production environments.
  • ICC profile retention. Preserves all embedded color profiles during the compression process to ensure color accuracy. The technology maintains color fidelity on display devices and printing systems.
  • Command-line interface. CLI version for integration into automated systems and batch processing scripts. The tool provides parameterization options for deployment on servers and backend environments.
  • GPU-accelerated processing. Implementation that uses graphics processing units to speed up compression operations. The hardware acceleration significantly reduces processing times on compatible systems.
  • Cross-platform compatibility. Available for Windows and macOS operating systems with equivalent functionality on both platforms. Feature consistency allows deployments in heterogeneous environments.
  • Maximum compression mode. Specialized setting that applies additional reduction techniques for cases requiring extreme size minimization. This mode uses complementary algorithms to achieve beyond-standard reductions.

JPEGmini was developed by Beamr Imaging Ltd., an Israeli company founded in 2008. Development began in 2009 with the commercial launch of the first version in 2011. The technology uses C++ implementations for the core image processing algorithms, combined with graphical interfaces developed in native languages for each platform. The algorithms are based on research into human visual perception and psychovisually optimized compression techniques.
