FileVeil FAQ

Question 1

Can anyone see what's hidden inside my file?

Accepted Answer

No. All processing happens entirely on your device, nothing is ever uploaded to any server. If you use an encryption key, your hidden content is locked with AES-256-GCM encryption before files are hidden inside the cover file. Without your key, the content is mathematically unreadable, even to us.

Question 2

Does FileVeil store my files or encryption keys?

Accepted Answer

Never. FileVeil has no servers that handle your files. Your encryption key is derived locally in your browser and is never transmitted anywhere. We have no technical ability to access your files or keys, by design.

Question 3

Is it possible to detect that a file contains hidden content?

Accepted Answer

In standard mode, a careful byte-level analysis could potentially reveal anomalies. With Stealth Mode (Pro+), hidden data is stored inside the file's own structure, making the output indistinguishable from an ordinary file to common inspection tools. The cover file opens, plays, and behaves completely normally.

Question 4

What encryption standard does FileVeil use?

Accepted Answer

FileVeil uses AES-256-GCM, the same standard used by governments, financial institutions, and security professionals worldwide. Pro+ users can enable Strong Encryption mode, which uses 300,000 PBKDF2 iterations for key derivation, 3× the standard, making brute-force attacks significantly harder.

Question 5

Does FileVeil collect any personal data?

Accepted Answer

We collect only what's necessary to run the service: your email address for account access, and payment details to activate your plan. We only collect essential account information, such as your email and account tier, and we never share your data with third parties except to process payments.

Question 6

Is FileVeil safe to use on shared or public devices?

Accepted Answer

FileVeil itself does not store files or keys between sessions. All processing happens locally in your browser, with files handled in-memory rather than being written directly to disk. However, on shared devices we recommend using a private browsing window and clearing it after use, as your operating system may cache files you work with locally.

Question 7

What exactly is steganography?

Accepted Answer

Steganography is the art of hiding information inside another file so that the existence of the hidden content is not apparent. Unlike encryption alone, which makes content unreadable but visible, steganography makes the hidden content invisible. FileVeil combines both: your files are hidden and encrypted.

Question 8

What file types can I use as a cover file?

Accepted Answer

FileVeil supports a wide range of cover file formats: images (JPEG, PNG, WEBP, BMP, GIF, AVIF, HEIC, TIFF), videos (MP4, MOV, AVI, MKV, WEBM, FLV, WMV), audio (MP3, WAV, FLAC, AAC, OGG, M4A, OPUS), documents (PDF, DOCX, XLSX, PPTX, EPUB), archives (ZIP, RAR, 7Z, TAR, GZ, BZ2), design files (PSD, AI, FIG, SKETCH, XCF), and system files (EXE, APK, ISO, DMG, DEB). The cover file continues to open and function normally after hiding files inside it.

Question 9

What can I hide inside the cover file?

Accepted Answer

Any file type. There are no format restrictions for files being hidden. Documents, spreadsheets, photos, videos, audio, archives, code files, or anything else. Free and Pro users can hide multiple files of the same type at once. Pro+ users can hide any combination of file types inside a single cover file. Pro and Pro+ users can also hide entire folders in a single operation.

Question 10

Will the cover file still open and play normally after hiding files inside it?

Accepted Answer

Yes. The output file is fully functional. An image still displays, a video still plays, an audio file still sounds the same. To anyone without FileVeil, it is simply the original file, nothing more.

Question 11

What happens to the file size after hiding files inside the cover file?

Accepted Answer

The output file will be slightly larger, roughly the size of the cover file plus the size of the embedded payload. This is expected and unavoidable. The approximate final size is shown to you before you download.

Question 12

Will hidden files survive if someone edits or compresses the cover file?

Accepted Answer

It depends on how the file is modified. Standard mode appends hidden data to the file; aggressive tools that re-encode or strip trailing data may remove it. Stealth Mode (Pro+) stores hidden data inside the file's own structure, making it more resilient to common edits. For maximum safety, avoid re-encoding or compressing the cover file after hiding files inside it.

Question 13

Can I hide files inside a cover file that already has hidden content?

Accepted Answer

Yes. This is the Multi-layer feature, available to Pro+ users. Each layer is independently encrypted and requires its own extraction pass. You can build multiple independent secrets inside the same cover file.

Question 14

Can I send FileVeil files to someone else?

Accepted Answer

Yes. For best results, send the file as a document or attachment rather than as a photo or media file. Some messaging apps and social platforms automatically compress, convert, or re-encode images, videos, and audio files, which may remove hidden content. To preserve hidden content, send the file without modification and avoid platforms that automatically alter files during transfer.

Question 15

How do I use FileVeil offline?

Accepted Answer

Offline access is available for Pro and Pro+ users. To use FileVeil offline, you must sign in at least once while connected to the internet. Once signed in, your session is saved on your device so you can continue using FileVeil without an internet connection.

Question 16

What's the difference between Free, Pro, and Pro+?

Accepted Answer

Free gives you 0.2 MB to try the core hide and extract features with AES-256-GCM encryption, no account required. Pro unlocks 500 MB file sizes and adds custom keys, batch file hiding, and offline mode. Pro+ goes up to 2 GB and adds every advanced privacy feature: Stealth Mode, Metadata Removal, Strong Encryption, Multi-layer file hiding, camera capture, and the ability to fully restore the cover file to its original state. One-time payment for both, no subscriptions, ever.

Question 17

Are payments truly one-time? No hidden fees?

Accepted Answer

Yes. You pay once and own it permanently. There are no monthly fees, no annual renewals, no feature gates that unlock over time. The price you see is the full price forever.

Question 18

What payment methods are accepted?

Accepted Answer

We accept credit and debit cards (Visa, Mastercard, Amex), PayPal, Apple Pay, Google Pay, and other local payment methods depending on your country. Payments are processed securely by Paddle, our Merchant of Record. Your plan is activated automatically the moment payment is confirmed.

Question 19

Can I get a refund?

Accepted Answer

Payments are non-refundable once plan access has been granted, as the features are immediately available upon activation. Please review the plan features carefully before purchasing. If you have questions before buying, contact us at support@fileveil.com.

Question 20

Can I upgrade from Pro to Pro+ later?

Accepted Answer

Yes. Simply purchase Pro+ and your plan upgrades immediately. Your account always reflects your latest purchase.

Question 21

Is there a free trial for Pro or Pro+?

Accepted Answer

There is no time-limited trial, but the Free plan lets you try the core functionality without any account or payment. This lets you verify that FileVeil works as expected on your device before committing to a paid plan.

Question 22

Do I need to install anything?

Accepted Answer

No installation required. FileVeil runs entirely in your browser using standard web technologies. You can also install it as a Progressive Web App (PWA) by tapping Add to Home Screen on mobile or Install in your desktop browser.

Question 23

Which browsers are supported?

Accepted Answer

FileVeil works on any modern browser that supports the Web Crypto API: Chrome, Firefox, Safari, Edge, Brave, Opera, and their mobile equivalents. We recommend keeping your browser updated for the best experience.

Question 24

Can I use FileVeil on mobile?

Accepted Answer

Yes. FileVeil is fully responsive and works on iOS and Android. Pro+ users can also use the camera directly within the app to capture photos and videos as cover files without saving them to the device first.

Question 25

Can I extract a veiled file on a different device from where I hid files inside it?

Accepted Answer

Yes. Transfer the veiled file to any device, open FileVeil in a browser, and extract. The file format is device-agnostic. If you used an encryption key, you'll need to enter that same key to unlock the content.

Question 26

Does FileVeil work offline?

Accepted Answer

Pro and Pro+ users can use FileVeil fully offline after installing it as a PWA. The Free plan requires an internet connection for account verification. File processing itself never requires internet, it's always local.
