FileVeil vs
Password-Protected ZIP

A password-protected ZIP is better than nothing. But when you send one, the person on the other end can already see what is inside before they type a single character of your password.

What a password-protected ZIP actually does

A password-protected ZIP file bundles one or more files into a single archive and encrypts the file contents so they cannot be read without the password. It is a practical tool and widely supported across every operating system and device.

When you send a password-protected ZIP to someone, they need the password to open and extract the files inside. Without it, the contents are unreadable.

That is what most people think is happening. And in terms of the file contents, they are right.

But the archive is not a sealed box. It is more like a labeled box with a lock on it.

The problem most people do not notice

In many ZIP implementations, the file names inside the archive are stored in the archive structure itself, not inside the encrypted contents. This means that someone who receives your ZIP can often see the list of file names before entering any password.

A ZIP file named "project.zip" that contains files named "Q3_Financial_Report.xlsx", "Board_Meeting_Notes.pdf", and "Salary_Data.csv" has already revealed a significant amount of information before the password is even requested.

The same is true for file sizes, which can hint at the nature of the content. And the ZIP file itself announces its purpose: it is obviously an archive, obviously password-protected, obviously containing something someone wanted to protect.

What is visible before the password

In many ZIP implementations: file names, file count, file sizes, and file types. The password protects the contents. It does not hide what those contents are.

How FileVeil is different

FileVeil takes a different approach entirely. Hide any file inside another file. That is the core of what it does. And when you do, nothing about the hidden files is visible. Not the names. Not the types. Not the sizes. Not even the fact that anything is hidden at all.

Instead of creating an archive, FileVeil takes your files and hides them inside an ordinary-looking file: a photo, a PDF, a video clip, an audio file. That cover file is what you send. The recipient sees a photo. They open the photo. The photo looks exactly like a photo.

The hidden files are encrypted with AES-256-GCM before being embedded inside the cover. So even if someone knew to look inside, they would need the correct key to read anything. The cover file name is set by you and reveals nothing. You could call it "vacation.jpg" and send it to anyone.

What is visible when you send a FileVeil file

Only the cover file. A photo looks like a photo. A PDF looks like a PDF. The hidden file names, types, sizes, and count are completely invisible to anyone without FileVeil and the correct key.

Which one to use

A password-protected ZIP is a reasonable choice when you need to bundle files for someone who needs to unpack them easily, and when the file names themselves are not sensitive. It is familiar, universally supported, and works without any additional tools in most cases.

FileVeil is the right choice when the file names are sensitive, when you want the recipient to see only what you choose for them to see, or when you want the transfer to look completely ordinary. A photo sent through any messaging platform. A PDF attached to an email. No ZIP. No archive. No signal that anything is being protected.

The question is not just "are the contents protected?" The question is "what does this file tell someone before they even open it?"

Free to try

"A ZIP tells people something is locked. A photo, a video, a PDF, an audio file tells people nothing at all."

Frequently asked questions

What is the difference between FileVeil and a password-protected ZIP?
A password-protected ZIP encrypts the file contents but still shows the file names to anyone who opens the archive. FileVeil hides your files inside an ordinary-looking file. A photo, a PDF, a video. No one can see the file names, the file types, or even that anything is hidden inside.
Can people see file names inside a password-protected ZIP?
In many ZIP implementations, yes. File names are stored in the archive structure and can be visible before the archive is decrypted. This means someone who receives your ZIP can see what files are inside before entering the password.
Does FileVeil show file names when you send it?
No. When you send a FileVeil file, the recipient sees only the cover file. A photo, a PDF, or whatever you chose. The names and types of the hidden files are completely invisible. The cover file name is set by you and reveals nothing about what is inside.
Is FileVeil safer than a password-protected ZIP?
They protect in different ways. A ZIP with strong encryption protects file contents. FileVeil protects file contents with AES-256-GCM encryption and also hides the existence of the hidden files entirely. The cover file looks like an ordinary photo, PDF, or video. Nothing about it suggests anything is hidden inside.
Do I need to install anything to use FileVeil?
No. FileVeil runs entirely in your browser. Nothing is installed, nothing is uploaded. The recipient also does not need to install anything. They open fileveil.com in their browser, load the file, enter the key, and extract.
Can FileVeil bundle multiple files like a ZIP?
Yes. FileVeil Pro supports unlimited files inside a single cover file, up to 500MB total. Pro+ supports up to 2GB. The files come out individually when extracted. No additional unpacking step needed.
