How to Hide Files So They Are
Even Harder to Find

By FileVeil Team · July 11, 2026 · 6 min read

Most people never inspect a photo beyond opening it. They see the image, they move on. But some situations are different. And for those, there is a level of hiding that goes further than the standard.

What standard hiding already does

When you hide a file inside a cover file with FileVeil, several things happen at once. The hidden file is encrypted before it goes in. So even if someone found it, they could not read it without your key. The cover file still opens normally, displaying exactly as expected. Nothing about the outside file looks unusual.

For the vast majority of situations, this is more than enough. Someone picking up your phone, browsing your files, or receiving the cover file through a messaging app has no reason to suspect anything is hidden inside. They see a photo. They open the photo. The photo looks like a photo.

Hidden and encrypted. For most people, for most situations, that combination is the end of the conversation.

Already private by default

Standard FileVeil hiding encrypts your files with AES-256-GCM and embeds them inside the cover. The cover still opens normally. What is inside is invisible and unreadable without the correct key.

What Stealth Mode adds

Standard hiding already keeps the cover file working normally. A photo opens as a photo. A PDF reads as a PDF. What is inside stays invisible and encrypted. For everyday use, that is everything you need.

Stealth Mode takes it one step further. The cover file not only looks normal. It carries the hidden content in a way that is harder to distinguish from a file that has nothing inside at all. The difference is not visible to someone casually browsing your files. It matters in situations where the inspection goes beyond casual.

Nothing about how you use it changes. Pick a cover file, add the files you want to hide, set a key, download the result. Stealth Mode is a toggle. It changes how the hiding is done, not what you do.

Available on Pro+

Stealth Mode is a FileVeil Pro+ feature. It works with JPG, PNG, MP3, and PDF cover files. For other file types, FileVeil uses standard hiding, which already keeps your files completely private and the cover file working normally.

Any file can be hidden

There are no restrictions on what you hide inside the cover. Documents, photos, videos, spreadsheets, audio, archives, code, anything. The cover file format is what determines whether Stealth Mode is available, not the files inside.

If you are hiding files for personal storage, sharing with someone you trust, or keeping documents private from casual access, standard hiding is the right choice. It is private, it is fast, and it works on any cover file.

Stealth Mode is for situations where you want that extra step. When the question is not just "is this private?" but "how private can this be?"

How to enable Stealth Mode

01

Open FileVeil and go to Hide mode

Go to fileveil.com and make sure you are on the Hide tab. Stealth Mode is a hiding option and is not available in Extract mode.

02

Enable Stealth Mode in the options panel

Find Stealth Mode and toggle it on. Choose a JPG, PNG, MP3, or PDF as your cover file. These are the formats Stealth Mode supports.

03

Add the files you want to hide

Select the files to embed inside the cover. Any file type works as the hidden content. Only the cover file format matters for Stealth Mode.

04

Set a key (optional, but recommended)

Add a password. Even with Stealth Mode, a key ensures that if someone did find the hidden content, they still could not read it without the correct password.

05

Download and use as normal

The result looks exactly like the original cover file. Store it, share it, or send it through any platform. Extracting works the same way as always. Open FileVeil, load the file, enter the key.

When Stealth Mode matters

Standard hiding is enough for most people most of the time. Stealth Mode is for situations where that is not the right measure.

🏠
Family archives
Passport copies, insurance documents, property records hidden inside family photos for long-term storage. Stealth Mode keeps them even less noticeable over time.
✈️
Traveling with document backups
Carrying backup copies of a visa, hotel confirmation, or ID inside ordinary travel photos. Less likely to draw attention, whatever the situation at the destination.
📋
Personal contracts and records
A signed agreement, a financial record, a private correspondence. Stored in a cover file that gives no indication anything is inside.
🎨
Creative work before release
Drafts, unreleased projects, source files hidden inside something ordinary while the work is still in progress. Nothing to see until you decide otherwise.
💼
Professional and sensitive use
Carrying client files, source material, or private correspondence in situations where discretion matters at every level, not just to a casual observer.
🛡️
When you want the highest level
Some people want the strongest hiding available, regardless of whether their situation strictly requires it. Stealth Mode is that option.
"Standard hiding makes the file look normal. Stealth Mode makes it look like nothing was ever done to it at all."
