Any files, or a folder
Your files stay on your device
How to use it
Drop files here to zip them up, or drop in a zip to see what’s inside and take files out. Nothing to install, and your files stay private.
To make a zip: drop your files (or a whole folder) onto the box above and click Zip. Folders keep their structure inside the zip.
To open a zip: drop it in to see every file inside with its size. Save just the one you need, or all of them.
Zipping photos, videos, or PDFs? They’re already squeezed, so zipping won’t make them much smaller — pick “store only” to bundle them faster. Text, spreadsheets, and code shrink a lot.
No upload wait and no size limits — unlike online zip sites, your files never leave your device.
FAQ
How do I zip files without installing anything?
Drop them here and click Zip. Your zip downloads straight away.
Is there a size or file limit?
No limit from us. Very large sets just depend on your device’s memory.
Can I open a password-protected zip?
No, sorry — that’s not possible in a browser yet.
Does it open RAR or 7z files?
No, only zip files.
Why is my zip the same size as my files?
Photos, videos, and PDFs are already compressed. Text and code files shrink much more.
Can I zip a whole folder?
Yes. Drag the folder in and its structure is kept.
How it worksFor the curious
Compression and extraction use fflate on a background thread, so large archives do not freeze the page. Limits are your device’s memory, since files are held in memory while the archive is built.
Password-protected zips cannot be opened: zip decryption needs a step no browser API provides. Only zip is supported — rar, 7z, and tar.gz use different container formats. Both cases are detected and explained.
JPEG, PNG, MP4, and PDF compress internally, so deflating them again costs time for almost no saving.
