A short companion for Zip Builder: when it is useful, what it expects, and what to check before using the result.

What it does

Pick a handful of files and get one zip back, without installing anything. The archive is assembled in the page from the bytes already on your disk, so nothing is uploaded, and a compression level lets you trade a little time for a smaller download.

Use the tool

Open Zip Builder, add the input the tool asks for, run it, and check the output before using it elsewhere.

Input and output

  • Input: text.
  • Output: text.
  • Category: Web.

Privacy and processing

Processing happens locally in your browser. This tool does not upload the input to ilham.dev.

Questions

Why do two files with the same name both survive?

A zip cannot hold two entries under one name, so the second becomes name-1, then name-2 and so on. That keeps both files instead of quietly losing one.

Which compression level should I use?

The balanced level suits almost everything. Store only is quicker and is the right choice for files that are already compressed, such as a JPEG or another zip, where no level can help.

Is there a size limit?

Only what your device's memory allows, since the archive is built in the page. A few hundred megabytes of photographs is fine on a desktop and heavy on a phone.
