This tool uses WebAssembly to run the 7-Zip engine directly in your browser. There is no server involved: your files are processed locally and never uploaded anywhere. This is ideal for sensitive documents or private photos.
If you need to open a RAR archive instead, try Open RAR Online. To strip metadata from extracted photos before sharing, use EXIF Viewer. To merge extracted PDFs, see Merge PDF.
macOS supports ZIP and gzip natively but not the .7z format. The 7z format uses LZMA compression which typically achieves 30-70% better compression than ZIP, making it popular for large software distributions. Mac users usually need to install The Unarchiver or Keka. This browser tool removes that requirement entirely.
7z typically compresses 30-70% better than ZIP (especially for executables and source code) and supports strong AES-256 encryption. However, ZIP is supported natively on every operating system. For sharing files with others, ZIP is usually the better choice since recipients can open it without extra software.
Are my files uploaded to a server?
No. Everything happens 100% in your browser using WebAssembly. Your .7z files never leave your device and are never uploaded to any server.
Can SammaPix create .7z files?
No, this tool extracts and converts .7z archives. It does not create them. You can download all extracted files as a ZIP archive, which is a free and universally supported format.
Can it open password-protected 7z files?
Yes. If the .7z archive is password-protected, a password field will appear automatically. Enter the password and the archive will be extracted.
Does it support multi-volume 7z archives (.7z.001, .7z.002)?
No. Multi-volume (split) .7z archives are not supported by the in-browser extractor. You will need a desktop application like 7-Zip for those.
Is there a file size limit?
The free plan supports .7z files up to 200 MB. For larger archives, a one-time 24-hour Day Pass ($2.99) removes this limit instantly.
Is it free to use?
Yes. Extracting .7z files up to 200 MB is completely free. No signup required.
Why can't macOS open .7z files natively?
macOS supports ZIP and gzip natively but not .7z. The 7z format uses the LZMA compression algorithm which requires a separate application or this browser-based tool.
