Folder structure is preserved inside the ZIP
How Folder Structure is Preserved
Click Add Folder to select an entire directory — the browser reads all files with their relative paths (e.g. src/utils/helper.ts) and stores them at those exact paths inside the ZIP. When extracted, your original folder structure is fully recreated.

Understanding Multi-Folder ZIP Creation
What is a Multi-Folder ZIP Creator?
A multi-folder zip creator bundles multiple directories and their contents into a single ZIP archive while preserving the complete directory hierarchy. Unlike a basic ZIP tool that flattens all files into the archive root, the multi-folder zip creator stores each file at its exact relative path — so a file at src/utils/helper.ts is stored at that same path inside the ZIP. When extracted, your original folder structure is fully recreated. This is essential for distributing projects, sharing build outputs, and archiving organised file collections.
How Our Multi-Folder ZIP Creator Works
- Add Folders and Files:Click "Add Folder" to select an entire directory — the browser reads all files with their relative paths using the
webkitdirectoryAPI. Click "Add Files" to add individual files, or drag and drop files directly. You can add multiple folders and files in any combination. - Instant Browser-Based Processing:Click "Create ZIP with Folder Structure" and the multi-folder zip creator builds a ZIP archive using fflate with DEFLATE level 9 compression. Each file is stored at its exact relative path. A progress bar tracks each file as it is added. Your files never leave your device.
- Download Your ZIP:Once complete, a result card shows the file count, folder count, archive size, and compression ratio. Click "Download" to save your ZIP instantly. Extract it on any OS to restore the original folder structure.
What Gets Stored in the ZIP Archive
- Full Relative Paths: Every file is stored with its complete relative path (e.g.
project/src/index.ts), recreating the exact folder hierarchy on extraction. - All File Types: The multi-folder zip creator accepts any file format — source code, images, documents, binaries, and configuration files are all bundled without modification.
- DEFLATE Level 9 Compression: Every file in the archive is compressed at the maximum DEFLATE level, producing the smallest possible ZIP output for your file set.
- Multiple Root Folders: You can add several top-level directories and they all appear as separate root folders inside the ZIP — ideal for bundling related but separate project directories together.
Browser Compatibility for Folder Selection
The Add Folder button uses the webkitdirectory attribute, which is supported in all modern browsers including Chrome, Firefox, Edge, and Safari. On mobile browsers, folder selection may not be available — use the Add Files button or drag and drop individual files instead. The ZIP archive itself is universally compatible and extracts correctly on Windows, macOS, Linux, and all major archive tools.

Frequently Asked Questions About Multi-Folder ZIP Creator
A multi-folder zip creator bundles multiple directories and their contents into a single ZIP archive while preserving the complete directory hierarchy. Unlike a basic ZIP tool, the multi-folder zip creator stores each file at its exact relative path so your original folder structure is fully recreated when extracted. It runs entirely in your browser using fflate — no server upload required.
When you click "Add Folder", the browser reads all files with their relative paths using the webkitdirectory API. For example, a file at src/utils/helper.ts is stored at that exact path inside the ZIP. When you extract the archive, the folder structure is recreated exactly as it existed on your device.
Yes, completely. The multi-folder zip creator runs entirely in your browser using the fflate library. Your files are never uploaded to any server and never leave your device.

Yes. You can click "Add Folder" multiple times to add several separate directories, and they will all appear as separate root folders inside the ZIP. You can also mix folders and individual files in the same archive. The file tree panel shows all added content grouped by top-level folder before you create the ZIP.
The multi-folder zip creator uses DEFLATE level 9 — the maximum compression setting. Text files, source code, HTML, CSS, JSON, and log files typically achieve 60–90% size reduction. Binary files like images, audio, and video are already compressed and show minimal additional reduction.
The "Add Folder" button uses the webkitdirectory API which may not be available on all mobile browsers. On mobile, use the "Add Files" button to select individual files or drag and drop files into the drop zone. The resulting ZIP archive is fully compatible with all mobile extraction apps.
Since all processing runs in your browser, the practical limit depends on your device RAM. Most modern devices handle archives up to several hundred MB without issues. Very large folder trees (1 GB+) may be slow or cause memory warnings depending on your browser and available RAM.
On Windows, right-click the ZIP and select "Extract All" — Windows Explorer recreates the folder structure automatically. On macOS, double-click the ZIP to extract with Archive Utility. On Linux, run: unzip archive.zip. All major archive tools including 7-Zip, WinRAR, and The Unarchiver fully support the folder structure stored in the ZIP.
