The implementing tool sits at https://freetoolonline.com/zip-tools/zip-file.html and accepts both individual files and folders. Pick the items you want bundled, decide whether to add a password (optional, and removable later via Remove ZIP password), then click the convert button. The output is a single .zip archive your browser downloads to its default folder. For a more granular look at what the converter does and does not do (compression ratios, included metadata, supported source file types), see the companion disambiguation guide Zip File Converter - what it actually does.

Why trust these tools

  • Ten-plus years of web tooling. The freetoolonline editorial team has shipped browser-based utilities since 2015. The goal has never changed: get you to a working output fast, without an install.
  • No install, no sign-up. Open a tool and get a working output in seconds - nothing to download and no account to create. Tools that need heavy processing run it on our service, so even a low-powered machine gets the job done.
  • Analytics stops at the page view. We measure which pages get visited, not what you type or upload inside a tool. There is nothing to sign in to and no profile is attached to your input.
  • Open-source core components. The processing engines underneath (libheif, libde265, pdf-lib, terser, clean-css, ffmpeg.wasm, and others) are public and audit-able. We link to each one in its tool page's footer.
  • Free, with or without ads. All tools are fully functional without sign-up. The Disable Ads button in the header is always available if you need a distraction-free run.
