File Compressor

You can compress any type of file into ZIP archives, including documents, images, videos, audio files, code files, and more. The compressor supports all file formats and can handle multiple files simultaneously.

Our file compressor uses the JSZip library to create ZIP archives in your browser. You can choose compression levels from 1 (fastest, least compression) to 9 (slowest, best compression). All processing happens locally - no files are uploaded to our servers.

There's no strict limit, but performance depends on your device's memory. For best results, we recommend compressing files under 500MB total. Very large files may take longer to process or cause browser slowdowns.

Yes! You can upload ZIP files and extract all contents or individual files. The extractor shows file details including names, sizes, and types. You can download individual files or all extracted files at once.

Absolutely! All file processing happens locally in your browser. No files are uploaded to our servers, and we don't store any of your data. Your files never leave your device, ensuring complete privacy and security.

You can choose from 9 compression levels: 1 (fastest, minimal compression) to 9 (slowest, maximum compression). Level 6 provides a good balance of speed and compression ratio for most use cases.

Yes! When you select multiple files, the compressor maintains their folder structure in the ZIP archive. You can also organize files by creating custom folder structures before compression.

If compression fails, check that you have sufficient browser memory and that files aren't corrupted. Try reducing the number of files or using a lower compression level. For very large files, consider compressing in smaller batches.
