Tools.

A small set of utilities that run entirely in your browser. Nothing is uploaded to a server — your backup never leaves your device.

There's just one tool for now: a migrator for legacy 1.x backups. If you're already on 2.x, you don't need anything here.

Backup UpgraderLegacy

Converts a 1.x backup into a 2.x-compatible library and lists the plugins you'll need to reinstall.

EOL

LNReader 1.x reached end of life. This migrator is kept around for users still restoring old backups — most people can skip it.

More tools may land here over time.

Step 01 — Upload

Drop your backup.json here

or click to browse — max 50 MB

How it works

Reads your 1.x export and maps old plugin IDs to their 2.x equivalents.

Rebuilds the library file — novels, chapters, categories and progress carry over.

Download the 2.x file and reinstall the listed plugins, then restore in-app.

Step 02 — Result

Upload a 1.x backup.json and the converted library plus plugin list will appear here.
