  • .gz

Stays on your device. No size limit but your device's.

How it works and help

A little help along the way

Follow these steps. Every option is explained underneath. Everything happens in your browser; nothing in the archive is sent anywhere.

  1. Open the archiveDrop it on the page or press Choose a file. For a ZIP cut into parts (.z01, .z02 … .zip, or .001, .002 …), choose every part at once. Nothing is uploaded, and there is no size limit but your device's.
  2. See what is insideThe page says how many files there are and how large they are once taken out. Folders open with a press; Find a file looks through every name. Press the eye beside a file to preview a picture, text, sound or a video.
  3. Type the password, if it has oneLocked files show a padlock. Type the password you were given and press Unlock. It stays on the page and is never kept.
  4. Choose the filesEvery file starts chosen. Untick what you do not want, or tick a folder to choose everything in it.
  5. Take them outIn Chrome and Edge on a computer, Extract into a folder writes the files with their folders into one you choose. In every browser, Download saves one file as it is, or several as one ZIP your device opens by itself. Each row has its own download button too.
  6. Check for damageCheck for damage reads every file in full and compares it with the checksum it was saved with, then names any file that does not match.

Questions people ask

What is inside a .gz file?
Exactly one file, packed with gzip. The page saves it under the name the .gz header gives, or under the .gz file's own name without .gz when the header has none.
Is the file checked when it is unpacked?
Yes. Every .gz ends with a CRC-32 checksum and the file's length, and both are compared with what was unpacked. A file that is damaged or cut short is said to be, and not offered as whole.
What if the .gz holds a tar?
The page sees the tar inside, whatever the file is called, and lists its files and folders, so you can take out all of them or just the ones you need.
Why is the size shown with a note?
A .gz stores its length in 32 bits, so for a file over 4 GB, or one made of several joined parts, the stored size is wrong. The page says so, and the true size is known once it is unpacked.
