NKit to ISO Converter Tool

Convert .nkit.iso and experimental .nkit.gcz / .gcz files to plain ISO locally in your browser – private, fast, no upload.

📂 Drop NKit / GCZ Files Here
or click to browse
Supported: .nkit.iso • .nkit.gcz / .gcz (experimental)

Info

Disclaimer: Use only with backups you legally own. Some .nkit.gcz files need external recovery data for perfect restoration.
Note: .nkit.iso usually just needs a quick pass‑through. GCZ decompression here is simplified; unsupported block modes will show an error.

About This NKit to ISO Converter

This lightweight converter runs entirely inside your browser. Drag a .nkit.iso or .nkit.gcz / .gcz file, watch the progress bar, and download a standard ISO image. Nothing is uploaded; processing stays local for privacy and speed. A plain .nkit.iso is already normalized so conversion is effectively instant.

The interface is intentionally minimal: clear typography, simple buttons, and adaptive spacing that scale comfortably on phones, tablets, and desktops. Progress bars and status text keep you informed, while integrity hashes (MD5 & SHA‑1) let you verify results against known databases. Batch mode allows multiple files to be queued and processed sequentially while you do other tasks.

If a compressed GCZ block uses an unsupported pattern the tool reports the issue instead of producing a silent error, letting you switch to the full desktop utility for a perfect rebuild when needed. Use the tips below for smooth conversions and reliable archival results.

How to Use

  1. Click or drag your .nkit.iso or .nkit.gcz / .gcz file(s) into the drop area.
  2. Review each row: the tool identifies type, size, and shows a ready status.
  3. Press Convert on a single item or use Convert All for batch mode.
  4. Watch the live progress bar & percentage. Hashes appear after processing.
  5. Click Download ISO to save the reconstructed image locally.

Tips for Accurate Results

  • .nkit.iso is already normalized. Conversion is a safe, lossless rename.
  • For .nkit.gcz images missing recovery partitions, some padding sectors cannot be fully rebuilt – use original recovery data with desktop NKit if you need perfect Redump matching.
  • Keep plenty of free RAM for very large titles; close other heavy tabs first.
  • Verify the MD5 / SHA‑1 hashes against known good sets when archival accuracy matters.
  • If a block error appears, note the block index and process the file with the official tool to complete reconstruction.

For legitimate preservation of media you own, this streamlined converter provides a quick and private route from normalized or compressed containers back to plain ISO. Its small footprint and clear feedback aim to keep the process straightforward.
