WhatsApp backup for import and export: every supplier chat in one encrypted file
Supplier chats, foreign-language voice notes, specs and invoices live in WhatsApp. Keep them in one password-encrypted, searchable file with Kaption.
Kaption AI·Updated October 11, 2026
If you buy or sell across borders, WhatsApp is probably where the trade actually happens. The factory sends photos of the first production run, the buyer confirms the colour in a voice note in Portuguese, the forwarder shares the bill of lading as a PDF, and the price change you agreed on lives in a message from last March.
That record matters when a shipment arrives wrong, a supplier remembers the deal differently, or a new colleague takes over an account. This post explains how to keep the whole history in one password-encrypted file you can search and open on any computer, and what that file can and cannot do.

Why a trade business needs its own copy of WhatsApp
A typical import or export desk has, all in WhatsApp:
Supplier and buyer chats across several countries and time zones, some going back years.
Voice notes in other languages, often the clearest statement of what was promised.
Specs and quotes: carton sizes, materials, MOQ, payment terms.
Invoices, packing lists and shipping documents sent as PDFs.
Photos and videos of goods: samples, finished batches, damage on arrival.
All of it sits on one phone and one WhatsApp account. WhatsApp's own backup is there to move chats to a new phone, but you can't open it on a computer or search it. If the phone goes, or the account does, the history of every deal goes with it.
One password-encrypted file, in a folder you pick
Kaption is an extension for WhatsApp Web in Chrome and Edge, and a desktop app for Mac and Windows. Its Backups feature keeps one encrypted backup file of your WhatsApp chats in a folder you pick.
Password-encrypted. The file is locked with a password you choose, at least 10 characters. Nobody, not even Kaption, can open it without your password, and Kaption's servers never receive the file or the password.
Wherever you want it. Put the folder inside Google Drive, iCloud Drive or OneDrive and that service syncs the file like any other. An external drive works too. Kaption doesn't connect to those services; it only writes the file.
Kept up to date. On paid plans, Kaption adds what changed every hour. Nothing changed, nothing written.
Inside the file: every chat in the account, with messages, contacts, groups and labels; transcripts of voice notes made with Kaption; small profile pictures; and messages that were later deleted, marked "Deleted in WhatsApp". On paid plans it also holds the media: the photos of goods, videos, voice notes and documents.
Search across suppliers, languages and years
You open a backup in Kaption's viewer, read-only, in a new tab that looks like WhatsApp. Search covers every chat and every transcript in the file at once.
Find a spec. Search "carton" or a product code and see every chat where it came up, across all your suppliers.
Find what was said in a voice note. Voice notes transcribed with Kaption are searchable by their text, so you can find the supplier's spoken confirmation without listening to a dozen recordings. Search with the words in the language the voice note was spoken in.
Find the paperwork. Filter to chats with media, then open invoices, photos and videos as previews.
Other filters show only groups or only chats with transcripts. Everything is decrypted in memory on your computer; nothing is uploaded.
Open it on any computer
The backup is a single file. Copy it, keep it on a drive, or let your cloud folder sync it, and you can open it in Kaption on any computer with its password: the laptop you travel with, the office desktop, or a colleague's machine when you hand over an account (only if you choose to share the password).
On the Kaption desktop app the viewer can remember a backup's password with Touch ID or the system keychain, so you don't type it every time on your own computer.
What it doesn't do
It's view-only. Kaption doesn't restore chats into WhatsApp or move them to a new phone.
The password can't be recovered. Forget it and the backup can't be opened.
Some things aren't included: notes, reminders and AI summaries.
It needs a little attention. In Chrome or Edge, after a browser restart, the extension may ask you to allow access to the backup folder again.
It's not a legal record-keeping system. It gives you your own encrypted copy of what was said. Whether that is enough for a dispute, customs or an audit depends on your country's rules and your advisers.
Where it works, and on which plan
Kaption extension in Chrome and Edge: hourly backups, export and viewer.
Kaption desktop app for Mac and Windows: Backups in the left rail; the Windows app is an early beta. See the desktop app.
Safari has no Kaption extension.
The Free plan can export a one-off backup with messages and transcripts and open it in the viewer. Media and hourly backups are part of paid plans.

FAQ
Can I search voice notes in Chinese, Turkish or Italian?
You search their transcripts. Voice notes transcribed with Kaption are stored in the backup as text, so search with words in the language the supplier spoke.
Can I open the backup on a computer abroad?
Yes. The backup is one file. Open it in Kaption on any computer, with its password.
Are invoices and photos of goods included?
On paid plans, media is included: photos, videos, voice notes and documents. On the Free plan, an exported backup includes messages and transcripts.
Does Kaption store my supplier chats on its servers?
No. The file is written to the folder you pick, and Kaption's servers never receive the file or the password.
Can I restore the chats to WhatsApp if I lose my phone?
No. Kaption backups are view-only. They let you read and search your history, not put it back into WhatsApp.
