Create a ZIP file
Add any number of files and bundle them into a single .zip archive. Everything runs in your browser. Your files never leave your device.
About creating a ZIP
Each file you add becomes an entry in one .zip archive, packed with standard DEFLATE compression. Files with the same name are kept separate by appending a number, so nothing is overwritten. The result is a single ZIP you can share, email, or archive.
Does it shrink my files?
Sometimes. Text and other uncompressed data get smaller; already-compressed files like JPG, PNG, MP4, and MP3 stay roughly the same size, because they are already packed as tightly as ZIP can manage. For those, the ZIP mainly groups many files into one tidy download.
Is it private?
Yes. The archiver is a JavaScript library running on your own machine. Nothing is uploaded, stored, or seen by us. There is no server to send files to.
Frequently asked questions
- What files can I put in the ZIP?
- Any files. Add as many as you like, of any type, and they are bundled together into a single .zip archive in the order you add them.
- Will the ZIP make my files smaller?
- It depends on the files. Text, documents, and other uncompressed data shrink with ZIP's deflate compression. Already-compressed files — JPG, PNG, MP4, MP3, and most office documents — won't shrink meaningfully, because they are already packed. For those, a ZIP is mainly a way to group many files into one download.
- Are my files uploaded to a server?
- No. The archiver is a JavaScript library running on your own machine. Nothing is uploaded, stored, or seen by us, because there is no server to send files to.
- Is it free, and do I need an account?
- It is free with no watermarks, no daily caps, and no sign-up. Add your files, create the ZIP, and download it.
