A free ZIP file converter and extractor
FileCraft is a free ZIP file converter that works in your browser with nothing to install.

Archives are processed client-side on your device, so your files are never uploaded.
Frequently asked questions
How do I zip a folder online?
Drag the folder into the box above, or press Add a folder and select it. Its subfolders and files keep their structure inside the ZIP.
Why didn't my photos or videos get much smaller?
JPG, PNG, MP4 and similar formats are already compressed, so zipping can't shrink them much. Text, documents, spreadsheets and code usually compress well.
Is there a file size limit?
There's no fixed limit. Because everything runs in your browser, the practical limit is your device's memory: a few gigabytes on most computers, less on phones.
Can I password-protect the ZIP?
Not currently. The ZIP files created here are standard, unencrypted archives.
Are my files uploaded to a server?
No. Conversion runs entirely in your browser via client-side JavaScript, on your own device. Your files never touch a remote server and nothing is stored, so it's a secure, private, no-upload tool for personal photos and confidential data, and it keeps working on slow connections.
