How to create a ZIP file online

  1. Add your files

    Drop any files onto the tool, click to browse, or paste them from your clipboard. Every file type is accepted, and the archive starts building the moment files land.

  2. Pick a compression level

    Choose Store for the fastest bundle, Balanced for a good mix of size and speed, or Maximum for the smallest archive.

  3. Check the archive size

    The output shows how many files went in and the size of the finished .zip. Add or remove files and it rebuilds automatically.

  4. Download the .zip

    Click Download .zip to save the archive to your device, ready to email, upload, or store.

Why use this tool

Any file type

Documents, images, audio, code, spreadsheets, or a mix of all of them go into the same archive. There is no restriction on what you can bundle.

Three compression levels

Store copies files in with no compression for speed, Balanced trades size against time, and Maximum squeezes the archive as small as it will go.

Duplicate names kept apart

Two files that share a name are numbered automatically, so nothing is silently overwritten inside the archive.

Rebuilds with every change

There is no build button. Adding a file, removing one, or switching the compression level regenerates the .zip on its own.

Private by construction

The archive is assembled on your device, so contracts, source code, and personal files are never uploaded.

Free without a catch

No account, no watermark, and no cap on the number of files beyond what your browser memory allows.

About this tool

This tool bundles any set of files into a single .zip archive without anything leaving your browser. Drop documents, photos, audio, or code in any combination, and the archive is assembled on your device the moment the files land. There is no build button: adding a file, removing one, or changing the compression level rebuilds the .zip automatically, and the output reports the finished size before you download.

A ZIP archive is the simplest way to hand someone many files at once. Instead of attaching a dozen loose items to an email, or dragging a folder that a chat app refuses, you get one tidy file to send, upload, or store. Store keeps the original bytes for the quickest bundle, Balanced applies moderate compression, and Maximum works hardest to shrink text-heavy content like logs and source files. Already-compressed formats such as JPG, MP4, and PNG will not shrink much further, so Store is often the fastest sensible choice for those.

Because everything runs on your device, sensitive material like signed contracts, private keys, and personal photos stays where it is. Very large sets are held in memory while the archive is built, so extremely big collections can strain a browser; splitting them into a few smaller archives helps. When the files you want to bundle are documents, images to PDF can combine pictures into one PDF first, and merge PDF joins separate PDFs before you add them. To confirm a downloaded archive matches what you sent, run it through the file hash generator.

Frequently asked questions

How do I create a ZIP file?
Drop the files you want to bundle onto the tool, or click to browse. They are combined into a single .zip archive the moment you add them. Pick a compression level, then download the archive.
What types of files can I add?
Any type. Documents, images, audio, video, spreadsheets, and code can all go into the same archive, on their own or mixed together. Nothing is off limits.
What does the compression level do?
Store bundles files with no compression for the fastest result. Balanced applies moderate compression for a good mix of size and speed. Maximum squeezes the archive as small as it will go, which takes longer and helps most with text-heavy files. Photos and videos are already compressed and will not shrink much.
What happens if two files have the same name?
They are kept apart automatically. The second file with a shared name is numbered, so both end up in the archive and neither is overwritten.
Are my files uploaded anywhere?
No. The archive is built entirely in your browser. Your files are never uploaded, never stored, and never leave your device.
Is there a limit on file size or count?
There is no fixed limit, but every file and the finished archive are held in memory while it is built. Very large collections can run a browser out of memory, so splitting them into a few smaller archives is safer.
