ZIP archive maker
Pack files into a ZIP or unpack one.
Drop the files you want to pack
or click to choose. Up to 200 MB per file.
We add the .zip extension for you.
Your browser does the packing and the files are never uploaded. Photos, video and music are only stored in the archive: they are already compressed, and another pass would not shrink them, only make you wait.
- Runs right in your browser
- Free, no sign-up
More about ZIP archive maker
How to pack files into a ZIP
Drop in the files, name the archive and download it. Packing runs in your browser, so nothing is uploaded: contracts, photos and exports all stay on your computer. One ZIP is easier to send than fifteen attachments, and mail servers prefer it too.
How to open an archive
Switch to unpacking and drop a ZIP in. You get the list of what is inside and can pull out a single file without unpacking everything. Useful when someone sends a 200 MB archive and you need one PDF out of it.
Frequently asked questions
Will a ZIP make my photos smaller?
Barely. JPEG, PNG, MP4 and MP3 are already compressed, so a ZIP saves a few per cent at best. It shines on text, spreadsheets and documents, where it can halve the size or better. For photos, use the image compression tool instead.
Can the archive be password-protected?
Not here. Encrypted ZIPs need a desktop program; this tool neither creates nor opens them.
How many files can it handle at once?
Dozens without a problem. Everything is packed in memory, so with several gigabytes the browser can run out of room; in that case pack the files in two or three batches.
Will the archive open on Windows?
Yes. It is an ordinary ZIP that Windows, macOS and Linux all open with no extra software.
