    FAQ

    Frequently Asked Questions

    How long does the compression take?
    The actual compression on our servers usually takes just a few seconds. The total time you wait depends almost entirely on your internet connection's upload and download speeds. You’ll see a live progress bar while the tool works.
    Can I pack multiple files or folders into one archive?
    Yes. You can drag and drop multiple files or entire folders directly into the page. Everything you drop will be packed into a single .7z file, and your original folder structure will be perfectly preserved.
    Is this tool actually free for large files?
    Yes, it is 100% free. There are no paywalls, no hidden fees, and no account registration required. We easily handle massive uploads, so files and folders well over 1 GB are welcome.
    How much smaller will my files actually get?
    It depends entirely on what you're uploading. Thanks to the powerful LZMA2 compression algorithm, text documents, logs, and uncompressed audio (like WAV) can shrink by 70% or more. However, files that are already highly compressed—like MP4 videos, MP3s, or JPEG photos—won't get noticeably smaller. For those, the main benefit is neatly packing many files into one easy-to-share archive.
    Do I need to install any software?
    You don't need any software to create the archive — that happens right here in your browser (Chrome, Safari, Edge, Firefox). However, you or your recipient will need an extractor (like 7-Zip or Keka) to open the file once it's downloaded.
    What happens to the files I upload?
    They are automatically and permanently deleted from our servers 2 hours after your session ends. All uploads and downloads use a secure HTTPS connection, and we never view, copy, or keep your data.
