> Lock any file on your iPhone with an AES-256 password before you send it: a protected ZIP for any file type, or a locked PDF. Nothing is uploaded.

To password protect a file on iPhone before sharing it, pack it into a password-protected ZIP, or, if it is a PDF, lock the PDF itself with a password. Both take a minute in Safari with Filevale, and the encryption happens on your phone, so the file is never uploaded. This guide covers both routes, what the person on the other end needs, and the options iOS already gives you.

## Why the Files app alone isn't enough

The Files app can compress files into a ZIP, but it can't add a password to it. Messages, Mail and AirDrop send a file exactly as it is, so anyone who gets hold of it can open it. To lock the file itself, you need to encrypt it before you share it.

## Lock any file in a password-protected ZIP

[Open Password-Protect ZIP](https://filevale.com/zip-with-password/)

This works for any type of file: photos, videos, Word or Excel files, scans, or several files at once.

1. Open [Password-Protect ZIP](/zip-with-password/) in Safari and tap the drop area to choose the files you want to pack.
2. Enter the password.
3. Tap **Encrypt**. The button shows how many files will go into the ZIP.
4. Download the ZIP and share it from your phone as usual.

The files are encrypted with AES-256 inside your browser. The password and the files never leave your device, and Filevale never sees or stores the password.

The easiest route on iPhone is the free [Filevale for iPhone](/go/ios?src=guide) app, which has the same kind of tools working on-device. The browser tool above is the no-install alternative.

## Lock a PDF with its own password

If the file is a PDF, you can protect the PDF directly instead of wrapping it in a ZIP. The recipient then opens it like any other PDF and is asked for the password.

1. Open [Password Protect PDF](/password-protect-pdf/) and choose your PDF. You can add several at once.
2. Enter the new password, then tap **Protect**.
3. Download the locked PDF and share it.

The PDF is encrypted with AES-256 on your device. Without the password nobody can open it. For more on locking and later unlocking PDFs, see [how to make a password protected PDF](/guides/password-protected-pdf/).

## What the recipient needs to open it

A protected PDF opens in normal PDF readers once the password is typed. A protected ZIP is different: it uses the WinZip AES format, which the built-in Windows and macOS ZIP openers can't open. The recipient can use 7-Zip or WinRAR on Windows, The Unarchiver or Keka on Mac, most file managers on Android, or Filevale's [Unzip Files](/unzip/) tool in any browser, including on another iPhone.

Send the password a different way than the file. If the ZIP goes by email, share the password by text message or say it on a call. Anyone who has both the file and the password can open it.

## Built-in iPhone options

- **Notes** can lock individual notes with a password or Face ID. That protects them on your phone, not a file you send to someone else.
- **Pages, Numbers and Keynote** can add a password to a document. The recipient needs an app that opens those formats, so a PDF or ZIP is often easier to share.

## Clean the file before you lock it

A password stops strangers from opening the file, but the people you send it to still see everything inside, including hidden metadata. [Remove Metadata](/remove-metadata/) strips GPS location and camera details from photos and videos, and author and company from PDF, Word, Excel and PowerPoint files. Run it first, then encrypt the clean copy. For other ways to send files without a public link, see [sharing files privately from iPhone](/guides/share-files-privately-from-iphone-without-a-public-link/).

## Frequently asked questions

### What if I forget the password?

It can't be recovered. AES-256 has no back door, and Filevale never sees or stores the password, so write it down somewhere safe before you share the file.

### Is my file uploaded when I encrypt it?

No. Both Password-Protect ZIP and Password Protect PDF run entirely in your browser, so the file and the password stay on your iPhone. That makes them suitable for IDs, contracts and other confidential files.

### Can I protect several files with one password?

Yes. Password-Protect ZIP accepts several files at once and packs them into one encrypted ZIP with a single password. If you only need to bundle files without a password, [Create ZIP](/create-zip/) makes a plain ZIP, with the password left optional.
