About Zip Files

The quickest way to send ten attachments as one is to zip them into a single file online, right here in your browser. It also helps when a form accepts a single upload and you have a stack of scans. The ZIP is built on your device and the files are never uploaded, so it's quick even on a slow connection and nothing is left on a server afterwards.

Add files in as many rounds as you like, remove any you picked by mistake and name the ZIP before you download it. Files that compress well, like TXT, CSV, logs or BMP images, get smaller. Photos, videos, PDFs and DOCX files are already compressed, so they're stored as they are. Names are saved in UTF-8, so any language survives, and each file keeps its original date.

How to use Zip Files

  1. 1
    Choose your files

    Click Choose files or drop them on the page. They stay on your device the whole time.

  2. 2
    Add or remove files

    Use Add files to zip files from other folders too, and the × next to a file to take it off the list.

  3. 3
    Name the ZIP

    Type a name in the ZIP name box. With a single file, it's filled in with that file's name.

  4. 4
    Create and save

    Click Create ZIP. Your browser builds the archive, downloads it and shows the final size.

Why use Cubfile for this

  • Nothing leaves your device

    Your browser reads and packs the files. No upload, no copy on a server, no waiting in a queue.

  • Doesn't use your daily tasks

    Browser tools don't count toward the free daily limit, so you can make as many ZIPs as you need.

  • Compression where it helps

    Plain text and other compressible files shrink, while JPG, MP4, PDF and similar formats are stored as-is to save time.

  • Clean names and dates

    File names are saved in UTF-8, dates are kept, and a second report.pdf becomes report (2).pdf instead of overwriting the first.

FAQ

Zip Files: questions and answers

Are my files uploaded when I zip files here?
No. The ZIP is made entirely in your browser, and the files never leave your device.
How many files can I put in one ZIP?
There's no set number; the only cap is 2 GB in total per ZIP. Because everything happens in your browser, it doesn't use up your free tasks for the day either. If the finished ZIP is too big to email, Split ZIP breaks it into volumes that fit email limits.
Will zipping make my photos smaller?
Barely. JPG, PNG, HEIC and MP4 files are already compressed, so they go into the ZIP as they are. Text files, CSV exports, logs and uncompressed images shrink the most. To make the photos themselves smaller, Compress Image shrinks JPG and PNG files with no visible loss.
How do I zip files from different folders?
Choose files from the first folder, then click Add files and pick more from the next one. They all end up side by side in the same ZIP.
Can I add a password to the ZIP?
Not with this tool. To lock the archive, use Password Protect ZIP, which creates an AES-256 encrypted ZIP.
Share Zip Files with a friendIt runs in any browser, and they can try it without signing up.
