No file upload

This operation runs with browser APIs. Nirmion receives catalogue requests, not the selected source bytes.

Original stays unchanged

The converter creates a separately named output. It never writes back into the source file.

Bounded work

Up to 20 files, 25 MB per file and 50 MB combined. Folder trees and password encryption are not included.

Plain-language method

How the archive is assembled

Nirmion reads the selected bytes, resolves duplicate portable names, compresses entries with DEFLATE, and writes a standard ZIP. Source files are not changed.

01
Choose a valid source
Choose only files you are authorised to package. Selection order does not create folders.
02
Review the conversion choices
Fast uses less compression work; Smallest spends more browser time. Archive name is cleaned for common operating systems.
03
Inspect the separate result
You receive one .zip file containing all selected entries with collision-safe names.

Useful when

Practical jobs this tool handles

Send a small project handoff as one attachment.
Group reports and supporting files for storage.
Package browser-generated assets before sharing.

Before converting

Check the package

Keep the tab open while compression runs.
Open the finished ZIP and confirm every expected entry.
Use a dedicated encrypted archive tool when a password is required.

Know the boundary

Not an encrypted archive

This tool does not add a password or hide filenames. Compression reduces repetition; it is not a security control.

Quick answers

Questions before you convert

The archive follows a deliberately simple ZIP contract.

Are folders preserved?

No. Browser-selected files are placed at the archive root in this release.

What happens to duplicate names?

A numeric suffix is added so no selected file silently replaces another.

Does smallest always make a much smaller ZIP?

No. Photos, video, PDFs, and existing archives are often already compressed.
