Create ZIP File Online — Free ZIP Archiver
Create a ZIP archive from multiple files online. Drag and drop files, then download as a single .zip. Free, browser-based.
Bundling multiple files into a single ZIP archive makes them easier to share via email, upload to cloud storage, or attach to a support ticket. This tool lets you drag and drop any number of files, preview the list, remove individual files, and then create a ZIP archive instantly in your browser using JSZip. The total size of all files combined must be under 100MB. Your files are never uploaded to any server — everything happens locally.
How to use
- Drag and drop files onto the upload area, or click 'Add Files' to open the file picker. You can add files multiple times to build up your list.
- Review the file list. Click the × next to any file to remove it before creating the archive.
- Click 'Create ZIP' and the archive downloads automatically to your computer.
FAQ
What file types can I add to the ZIP?
Any file type is supported — documents, images, videos, executables, archives, and so on. There is no restriction on the type of files you can include in the ZIP archive. The only restriction is the total combined size, which must be under 100MB.
What compression method is used?
The tool uses DEFLATE compression, which is the standard compression algorithm used in ZIP archives. Text-based files (documents, code, CSV, JSON, XML) compress significantly. Binary files that are already compressed (JPEG images, MP3 audio, existing ZIP archives) will not compress further and may appear at nearly their original size in the archive.
Can I add files from different folders?
Yes. Each file is added to the root level of the ZIP archive regardless of which folder it came from on your computer. If you add two files with the same name from different folders, the second file will overwrite the first in the archive. Rename files before adding them if you need to include files with identical names.
Is there a limit on the number of files I can include?
There is no limit on the number of files, only on the total combined size (100MB). You can add hundreds of small files. The browser processes the compression in memory, so very large numbers of files with a large combined size may use significant RAM.
What is the name of the downloaded ZIP file?
The downloaded file is named 'archive.zip'. There is currently no option to customise the output filename in this tool. If you need a specific name, rename the file after downloading it.
Are my files uploaded to a server?
No. All compression is done entirely in your browser using the JSZip library. Your files are never sent to any server. This makes the tool suitable for compressing confidential documents, source code, or any sensitive files.
