Sending several files
A single attachment is easier for the recipient to handle and stops one getting lost along the way.

What it is for
A ZIP file groups several files into one, preserving their names and folder structure. It is the universal format for sending sets of files: every operating system opens it without installing anything.
The main reason to use it is not so much saving space as grouping. Many web forms accept a single attachment, email clients get awkward with twenty loose files, and a download that arrives as one package is far harder to leave incomplete than fifteen separate downloads.
How much compression you get depends on the content. Text documents and spreadsheets shrink considerably, while photos, videos and PDFs are already compressed and barely reduce: in those cases the ZIP is for grouping, not for slimming.
How it works
- Drag the files you want to group into the upload area.
- Review the list and remove any if you made a mistake.
- Click "Process" and download a single .zip file with everything inside.
When to use it
Forms with one attachment
When a procedure accepts one file but asks for several documents, a ZIP is the standard solution.
Backups and archiving
Grouping a finished project’s documents into a ZIP keeps the folder tidy and everything together.
Practical tips
- Check the file names before compressing: they are preserved inside the ZIP, and renaming afterwards means redoing it.
- Confirm the recipient accepts ZIP files first. Some corporate mail filters block them for security.
- If the files are photos or videos, the ZIP will barely reduce the size. To make them smaller you have to compress the images first.
- The practical limit is your browser’s memory, not the tool. With very large sets it is better to make several ZIPs.
Frequently asked questions
Is there a file count or size limit?
There's no limit set by the tool itself; the real limit depends on the memory available in your own browser.
Do the original file names get kept?
Yes, each file keeps its exact name inside the resulting ZIP.
