Route
/mp4/decrypt
Canonical noun-first path on cryptvert.com.
Why teams protect MP4 videos
People use this route when they need to encrypt MP4 files online and want the browser to handle the workflow without a separate hosted locker.
When Cryptvert is better than native protection
Video files usually lack strong native password options. Cryptvert is better when you want to protect the whole MP4 before it travels outside your team.
Best for
- Demo videos shared with prospects or clients
- Internal training clips moved across departments
- Screen recordings or QA captures that expose sensitive product details
Not for
- Video transcoding, trimming, or editing
- Streaming playback inside the encrypted package
- Very mixed media bundles that belong on the generic /file route
Common use cases
- Vault product demos before external review
- Protect screen recordings during bug-report handoffs
- Encrypt training clips stored in shared drives
Mistakes to avoid
- Expecting the route to change codec, bitrate, or container
- Using the MP4 page for MOV footage that belongs on /mov/encrypt
- Forgetting that larger videos can take longer to process client-side
Quick checklist
- Confirm the video is .mp4 or .m4v
- Keep the tab open during client-side processing
- Download the .vault package after encryption finishes
- Share the passphrase separately from the file delivery

Visible FAQ
What does the MP4 decrypt route actually do?
Cryptvert decrypts a .vault package that originally contained a MP4 video and restores that file locally on your device.
Does Cryptvert transcode MP4 videos?
No. Cryptvert does not transcode MP4 files. It wraps the original video file and restores that same file after decryption.
Can this page accept M4V files too?
Yes. The MP4 route accepts both .mp4 and .m4v video files.
Why use a vault for video files?
Teams often use it to keep demos, reviews, and recordings out of open file shares while still using a simple browser-based workflow.
