Where your data is processed
Local files are processed in your browser, with no upload to WebFaz. If you open a package from a URL, your browser downloads the file directly from the server you entered.

Real-world use cases
Open a package and see what is inside
Situation: You received a RAR with photos from an event and want to find the right images.
- Drag the file (ZIP, RAR, TAR or 7Z, up to 100 MB) onto the “Drag your archive here” area or click to choose.
- If the package has a password, enter it under “Package password” before opening.
- Browse the folders and use “Search the package” to find a name or extension.
- Point 1: If the package has a password, enter it before opening.
- Point 2: You can also open a package from an address (URL).
Result: The list of the package’s files and folders, without having extracted anything.
View and extract only the files that matter
Situation: You need three images from a huge package.
- Click “View” next to a text file or an image to check it without extracting.
- When you find the right one, click “Download” on that row: only the chosen item is extracted.
- Use “Close package” when you are done.
- Point 1: Search by name, extension or folder to find the right file.
- Point 2: Preview opens text and images without extracting anything.
- Point 3: Download extracts only the item on the row. Use Close package when you finish.
- Point 4: The preview appears below the list, without extracting anything. Close it when you finish.
Result: Only the chosen files, extracted individually.
Open a package from a URL
Situation: The package is at an internet address and you do not want to download it first.
- Paste the address under “Or open from a URL” and click “Open URL”.
- If opening fails, the file’s server probably does not allow access from the browser: download the file and open it from your computer.
- Point 1: Paste the package address. If opening fails, the file’s server probably does not allow access from the browser: download the file and open it here.
- Point 2: Open URL tries to read the package straight from the address.
Result: The package opened straight from the address, when the server allows it.
Tips for a better result
- Be wary of packages from unknown sources: opening and viewing does not run anything, but do not run extracted programs without knowing where they came from.
- View before extracting: it is a quick way to confirm that the file is the right one.
- For huge packages, extract only what you need instead of everything.
Limits, and when this is not the best option
- Password-protected files and very large packages may not open.
- External URLs must allow access from the browser.
- The tool opens, views and extracts; it does not create archives.
