How it works
Three steps from a folder to a finished archive.
There is no upload queue and no sign-up. The archive is assembled in a worker inside the tab you already have open.
- 01
Add files or a folder
Drop files in, choose individual files, or select a whole folder. Relative paths are kept so nested files stay in their folders.
- 02
Create the archive
Compression is automatic. The result is a standard ZIP archive that opens in everyday ZIP tools.
- 03
Create and download
The archive is built in a Web Worker inside this tab. The result compares input and output bytes before you save it.
Features
A focused ZIP creator, not a file manager.
Add what you need, pick a level, and get a standard archive. No installation, no account, and no copies left on a server.
Folder paths intact
Nested files keep their relative folders instead of landing in one flat list.
Honest, byte-level results
Sizes are measured from the actual bytes you add and the archive you receive. No rounded-up savings claims.
Cancel a running job
Compression runs in a Web Worker. Cancel stops the work without downloading a partial archive.
No upload endpoint
There is no file server and no analytics in the tool. The only network request is the page itself.
Nothing installed
No desktop app, browser extension, or account. The tool runs in the tab you already have open.

Guide
Create a ZIP file online: files, folders, and downloads.
A ZIP creator combines separate files into one archive. This guide covers multiple files, folder structure, mobile use, and the difference between creating and compressing a ZIP.
Create a ZIP from multiple files
Use Choose files or drop several files onto the tool. Each file becomes an entry in one archive, and the original names are kept. If two selected files share a name, the tool adds a number so nothing is overwritten. You can remove an item before building the archive. When the list is ready, select Create ZIP. Compression is automatic, and the worker assembles the archive in the tab; there is no upload queue and no server copy.
Create a ZIP file from a folder
Choose a folder to include its files and nested directories. Relative paths are preserved, so images/cover.png stays inside images/ instead of being flattened. Empty directories selected through a folder picker are not included. If you need an empty folder in the archive, add a placeholder file or build the ZIP with a desktop tool. Folder support depends on the browser exposing a directory picker; on phones, the file picker may only allow individual files.
Download and open the archive
After the archive is built, the result panel shows the input size, output size, file count, and the archive name. Select Download ZIP to save it. The output uses standard DEFLATE compression and opens in Windows Explorer, macOS Archive Utility, 7-Zip, and most upload forms. If the archive is larger than the files you added, that is normal for small or already-compressed inputs; ZIP adds headers and a central directory.
Create a ZIP file on Android or iPhone
The creator works in modern mobile browsers. Files are read on the device and the archive is generated locally, so nothing is uploaded. Mobile file pickers may limit folder selection, and large archives can exceed available memory. For a big job, use a desktop browser. For a few documents or photos, the phone is usually fine.
ZIP Creator vs ZIP Compressor
These are two different jobs. The ZIP Creator takes separate files or folders and combines them into a new archive. The ZIP Compressor takes an existing .zip and rebuilds it at a different compression level to try to make it smaller. Creating an archive does not guarantee a smaller total size, and compressing one does not add new files. Use the creator when you need one file to send; use the compressor when you already have a ZIP that is too large.
File types and limits
Any file type can go into a ZIP: documents, images, audio, video, code, and folders. The tool accepts up to 1 GB of input in total, 512 MB per file, and 100,000 entries. Archive names are limited to 80 characters and paths to 512 characters. These limits keep the archive in browser memory. Password protection is not available, and the output does not use ZIP64.
Troubleshooting
If the Create ZIP button does not appear, add at least one file or folder. If a file is rejected, check the per-file and total limits. If the browser cannot read a folder, try selecting its files individually. If the worker stops, close other tabs and try a smaller set. If the archive will not open, confirm the download finished and that your ZIP tool supports standard DEFLATE archives. The tool never uploads files, so a network error will not affect an archive that was already generated.

Loading the page fetches its HTML, CSS, JavaScript, fonts, and icon. Those requests do not contain your files. As with any website, the hosting provider may process standard connection logs for the page request itself; the tool does not send your content anywhere.
FAQ
Questions before you start.
Still unsure about a limit or a result? Start with the answer here, then try the tool with a small sample.
How do I create a ZIP file online for free?
Open the ZIP Creator, add files with Choose files or by dropping them onto the tool, then select Create ZIP. Wait for the archive to finish and select Download ZIP. There is no account, payment, or upload step.
Can I combine multiple files into one ZIP?
Yes. Add as many files as you need, up to the total size and entry limits. Each file becomes a separate entry in one archive. If two selected files share the same name, the tool adds a number so nothing is overwritten.
Can I create a ZIP file from a folder?
Yes. Use “Choose a folder” or drop a folder onto the tool. The browser walks the folder and keeps relative paths inside the ZIP, so nested files stay in their folders. Empty directories selected through a folder picker are not included.
Can I make a ZIP file on Android or iPhone?
Yes. The creator runs in modern mobile browsers, and files are processed on the device rather than uploaded. Mobile file pickers may limit folder selection, and large archives can exceed available memory. For a big job, use a desktop browser.
Does creating a ZIP file always reduce file size?
No. ZIP can shrink text, code, and other repeatable data, but photos, video, audio, and already-compressed files may barely change or can grow slightly because the archive adds headers. The result panel reports the real input and output sizes instead of promising a saving.
Are my files uploaded to a server?
No. The archive is built inside your browser with JavaScript and a Web Worker. Selecting files, compressing, and downloading all happen on your device. No file content is sent to YunoNext.
Can I choose the ZIP archive name?
Yes. Enter a name in the Archive name field before creating the ZIP. The .zip extension is added automatically, and invalid filename characters are removed. The name is limited to 80 characters.
Can I create a password-protected ZIP?
No. The tool cannot create encrypted archives. If you need a password, create the ZIP here and then encrypt it with a desktop archive tool such as 7-Zip or WinRAR.
What are the file limits?
An archive can contain up to 1 GB of input, with a 512 MB limit per file and 100,000 entries. The limits exist because the browser holds the archive in memory.
Will the ZIP open on Windows and macOS?
Yes. The output is a standard ZIP with DEFLATE compression and no ZIP64 extension. That keeps it compatible with Windows Explorer, macOS Archive Utility, 7-Zip, and common third-party tools.

Already have a ZIP that could be smaller?
