Newest edit wins, or you choose
If you edited the same note on two devices, the newest edit is kept. Review each one side by side, pick the other version, or keep both.
For JW Library on more than one device
Your notes and highlights, on every device.
JW Library keeps your study data separately on each phone, tablet and computer. JWL Merger combines the backups from all of them into one, so every device ends up with the same notes, highlights, bookmarks, tags and playlists.

The demo uses example backups. Nothing leaves this page.
Why you need it
JW Library does not sync your notes between devices
A note you write on your phone stays on your phone. Highlights made on the tablet at the meeting never reach your computer. Over the years every device collects a different part of your personal study.
JWL Merger brings those parts together. Add the backups from every device, including old ones, and restore one complete backup everywhere.

How it works
Three steps, a few minutes
You only need a web browser. Use any one device to do the merge.
- Step 1
Back up each device
In JW Library on every phone, tablet and computer, create a backup and save it somewhere you can reach, like iCloud Drive, Google Drive or OneDrive.
Settings › Backup and Restore › Create a backup - Step 2
Merge them in your browser
Open JWL Merger, choose all the backups at once and tap Merge. A preview shows what each device will gain before anything is saved.
Choose backups › Merge backups - Step 3
Restore it everywhere
Save the merged backup, send it to your other devices, and restore it in JW Library. Every device now has the same study data.

Features
Careful with every note you have written
Built around how JW Library actually stores your study data, so notes stay attached to the right verse, article and paragraph.
No duplicates
Notes typed twice, identical highlights, and repeated audio and video are kept once. Overlapping highlights of the same colour can be combined too.
Safety checks before saving
Every note and highlight from every backup must be in the result, and the database must pass an integrity check. If anything fails, nothing is saved.
Bring back old backups
Add backups from an old phone or from years ago. Notes you thought were lost come back alongside today's.
Choose what to merge
Leave out notes, highlights, bookmarks, tags, favourites, filled-in answers or playlists if you only want part of your data combined.
Undo for 7 days
Keep your original backups on your device for a week, so you can go back to any of them if something is not right.
Send it with a QR code
Scan a code on your other device and the merged backup opens there, ready to restore. Or send it with Beam-It, directly between devices.
Clean up one backup
Add a single backup to remove the duplicate audio and video items that build up in playlists over time.
List of your publications
Optionally get a list of every publication you have notes or highlights in, with a jw.org link to download each one again.
Health check for every backup
Each backup is checked as you add it. A damaged one is refused, and you are told if one is empty, added twice or much older than your newest.
Main backup for bookmarks
The newest backup is picked as your main one and its bookmarks are the ones kept. Choose another, or combine the bookmarks of every backup.
See what is new, one by one
Before saving, open the list of new items grouped by device and publication, and search every note in the merged backup.
Works without internet
After the first visit the app opens and merges with no connection, and you can add it to your Home Screen like an app.
One folder for your backups
On a computer with Chrome or Edge, choose the folder where you keep backups once, then add them all with one button.
Monthly reminder
Add a repeating reminder to your calendar, so you back up and merge again before your devices drift apart.
Privacy
Your personal study stays on your device
JWL Merger opens and merges your backups inside your own browser. There is no account and no server that stores your notes.
- Backups are never uploadedThe merge runs entirely on the phone, tablet or computer you use.
- QR sharing is locked and temporaryIf you choose Send with a QR code, the file is locked on your device first. Only that code can unlock it, and the copy is deleted after one hour.
- Nothing saved until you say soThe preview shows every change first. Your original backups are never changed.
- No account, no trackingThere is no sign-up. The site only counts visits anonymously.

Does JW Library sync notes between devices?
No. JW Library keeps your notes, highlights and bookmarks separately on each device. To get the same ones everywhere, make a backup on each device, merge them into one, and restore that one backup on every device.
How do I move my notes to a new phone?
Make a backup on the old device and on the new one, add both to JWL Merger and tap Merge backups. Restore the merged backup on the new device. Nothing that was already on it is lost.
Is it safe? Are my notes uploaded?
Your backups are opened and merged on your own device, in your browser. They are never uploaded, except a locked copy if you choose Send with a QR code, which is deleted after one hour. Before saving, JWL Merger checks that every note and highlight from every backup is included.
Does it cost anything? Do I need to install it?
It is free, with no account. It works in any web browser on iPhone, iPad, Android, Mac or Windows. There is also an offline Windows version and a Mac app.
What if I edited the same note on two devices?
The newest edit is kept. After merging you can review each one side by side, choose the other version, or keep both as separate notes.
Can I undo a merge?
Yes. Keep your original backups until you have checked your notes. JWL Merger can also keep the originals on your device for 7 days, so you can restore one of them if something is not right.
Get every note back in one place
Add all your backups, old and new, from every device. It takes a few minutes and costs nothing.
