Create ZIP
Drop your files — or a whole folder — and they come out as a single ZIP archive, ready to attach to an email or set aside. The files never leave your device.
Your file stays on your device: nothing is uploaded
How it works
Drag in a folder and the structure is preserved, and two files with the same name in different folders stay two distinct files. With “Automatic” only what is worth compressing gets compressed: photos, video and audio are already compressed inside, and redoing it would cost waiting for nothing; text, CSV and source code shrink a lot. PDFs do get compressed: mostly-text ones often shrink by half or more, scans stay about the same, and trying costs next to nothing. If two files end up with the same name the second is renamed, and we tell you: nothing is silently overwritten.
Frequently asked questions
- Can I put a whole folder into the ZIP?
- Yes, drag it onto the page: every file inside goes in, including those in subfolders, with their paths. The button for picking files, on the other hand, selects individual files only. Empty folders don’t make it into the archive, since there’s nothing in them to add.
- How many files and megabytes can go into one archive?
- Up to 500 files, 150 MB in total; a single file can use the full 150 MB. For bigger collections, make several archives, for example one per folder.
- Why is the ZIP almost as big as the original files?
- Because many formats are already compressed inside: photos, video, audio, and even Word, Excel and PowerPoint documents, which are archives themselves. For a lighter archive, shrink the files first: “Compress images” for photos, “Compress PDF” for PDF documents.
- Can I protect the ZIP with a password?
- No, the archive comes out without a password. If what you need to protect is a confidential PDF, you can put the password on the document itself with “Protect PDF” before adding it: it stays protected even after someone extracts it.
