Free software for compressing images and documents, reducing file sizes by removing unnecessary metadata and optimizing compression algorithms.
FileOptimizer is a free desktop application for Windows, Mac and Linux that can significantly reduce the size of images and documents without affecting their quality or resolution. It works by stripping out excess metadata and optimizing compression to shrink files sizes.
For images, FileOptimizer supports JPEG, PNG, GIF, TIFF and BMP files. It can optimize compression settings, remove EXIF data that doesn't impact image quality, and convert between formats when beneficial. This allows creating much smaller image files that look identical to the originals.
For PDF documents, FileOptimizer can downsample and compress images within the PDF, decrypt and recompress encrypted PDFs, and remove redundant objects. It also supports optimizing Microsoft Office documents like Word, Excel and PowerPoint files by compressing images and removing revision history.
Overall, FileOptimizer enables easily reducing file sizes across many common document and image formats. This saves storage space and makes it faster to transfer, upload and download files without sacrificing quality.
