A file compressor reduces the size of files and folders by creating ZIP archives using compression algorithms. Our tool compresses multiple files into a single ZIP file, making it easier to share and store large amounts of data while reducing storage space and transfer time.
Simply select individual files or an entire folder using the buttons, or drag and drop files directly into the designated area. Then click the "Compress Files" button to create your ZIP archive. The compressed file will download automatically when complete.
Yes, absolutely! All compression happens entirely in your browser using client-side JavaScript. Your files are never uploaded to any server, ensuring complete privacy and security. Your data never leaves your device.
Yes! When you select a folder using the "Select Folder" button, the tool will compress all files and subfolders while preserving the complete directory structure. The folder hierarchy is maintained in the resulting ZIP archive.
You can compress any file type including documents (PDF, DOCX), images (JPG, PNG), videos (MP4), code files, and more. The compression algorithm works with all file formats, though already-compressed formats like JPG or MP4 may not reduce much in size.
While there's no strict limit imposed by the tool, very large files may be limited by your browser's memory capacity. For optimal performance, we recommend compressing files totaling less than 2GB at once. For larger archives, consider splitting them into smaller groups.
The compression ratio depends on file types. Text files, documents, and source code can compress by 50-80%, while already-compressed formats like JPEG images or MP4 videos may only reduce by 5-10%. The tool shows you the exact space saved after compression.
Yes! ZIP files created by this tool are standard ZIP archives that can be extracted using any ZIP utility on Windows, Mac, Linux, or mobile devices. You can also use our ZIP Extractor tool to extract files directly in your browser without installing any software.
