## What this tool does
Open a zip and pull out just the files you need — by name or extension, no software install.

## Typical user problems
- Someone sent a zip with everything and you need only part of it — and installing an archive tool for one extraction is overkill. Upload, filter by keyword, download the matching files.
- A 200 MB project archive and you need the three PDFs inside. Downloading and installing an unzipper for three files is the wrong tool for the job.
