The three steps
- Open the folder zipper at https://freetoolonline.com/zip-tools/zip-file.html. Drag the folder (or the loose files inside it) onto the upload slot. The browser sends the contents to the processing service over HTTPS.
- Optional: set a password. If the recipient needs a password-protected archive, switch to zip with password before uploading; the password is forwarded to the archive build so the .zip you download is already protected.
- Download the .zip. When the progress bar finishes, the link points to the packaged archive. That single file is what you attach, upload, or share.
How the server builds the archive
The processing service runs the ZIP build server-side: the upload pipeline accepts the folder contents, the ZipFileService routine bundles them (preserving sub-folder structure), and the resulting archive is written to S3-backed storage. The download URL is then surfaced back to the page. Because the build runs on the server, large folders are handled by the service rather than the browser tab - the only browser-side work is upload, progress display, and the final download. The archive on the server is rotated out after a short retention window, so the link is short-lived; download promptly. Folder structure inside the .zip matches the layout you uploaded, which means the recipient extracts back to the same shape.
Frequently asked questions
Is the tool really free to use?
Yes - no account, no sign-up, no card required. The upload pipeline accepts anonymous sessions; the archive is built, downloaded, and the working copies are cleared from the processing service after a short retention window.
Can I add a password to the archive?
Yes. The companion tool zip with password accepts a password during upload and forwards it to the archive build, so the .zip you download is already password-protected. The recipient needs the same password to extract.
Will my folder structure be preserved?
Yes. The archive build preserves the sub-folder layout, so when the recipient extracts the .zip they get the same folder tree you uploaded - useful for project handovers, photo trips organised by date, or document bundles with section folders.
