Add files to a ZIP

Select any file types. You can add more files in several rounds.

How to create a ZIP archive

  1. Add individual files or select a folder.
  2. Review and arrange the file list.
  3. Choose a filename and compression level.
  4. Create the ZIP, review the result, then save it.

Compression results

Text, CSV, XML and source code usually shrink well. JPG, MP4, PDF and other already-compressed files may show little additional reduction.

Privacy

The archive is created in your browser. Selected files are not uploaded by this tool.

How to use it well

About this create ZIP file online

Settings, real-world decisions, release checks and limitations.

Create a ZIP archive from selected files or an entire folder. Folder paths can be preserved so related project files stay organized when the archive is opened later.

Compression works best on text, CSV, XML and other repetitive data. Photos, video, audio and many PDFs are already compressed, so ZIP may package them without greatly reducing total size.

Common uses

  • Send several documents as one attachment
  • Package a project folder
  • Create a backup archive
  • Keep related form files together

Important limitations

  • Folder selection support varies by browser
  • Large archives depend on device memory
  • Already-compressed files may show little size reduction

Troubleshooting

The ZIP is not smaller

Many source files may already be compressed; ZIP can still be useful for packaging.

Folder selection is missing

Use individual file selection or a desktop browser that supports directory input.

A recipient cannot find files

Use simple folder names and avoid excessively deep nesting.

Create ZIP FAQ

Does ZIP always reduce size?

No. It always packages files, but already-compressed formats may barely shrink.

Can I add a complete folder?

Yes in browsers that support folder selection.

Are original files changed?

No. A new archive is created.

Can I password-protect the ZIP?

The current tool does not add encryption.

What filename should I use?

Use a short descriptive name with a date or version when helpful.
