Your archive stays on your device.
ZipFile.org is built as a static website with browser-based tools. The file tools are designed not to upload selected files to our servers.
File handling
When you choose a file in a tool, the browser reads it locally so the page can inspect or process it. The project does not require a login, database, upload endpoint, or server-side file processing.
Third-party scripts
The v1.3.1 project is built without third-party analytics or advertising scripts in the app code. If monetization is added later, it should never be placed in a way that confuses users into clicking fake download buttons.
Important limitation
Browser features and hosting environments vary. Review the source code before deploying changes, especially if you add analytics, ads, external libraries, or WASM archive engines.
