Usage guide
Send an image through a link that reveals it once
Send a diagram, reference photo, or visual instruction that the recipient only needs to inspect one time.
Check the image and upload size
JPG, PNG, GIF, and WebP are supported. Guest and Free uploads are limited to 1 MB; Pro allows 10 MB. Conversion can change the original image.
Set a password and create the link
Choose the image and a separate password. Unlocking the link yourself before sending it can use its single reveal.
The recipient unlocks and views it
After the image is successfully revealed once, additional reveals through the same link are blocked.
What this tool protects
Screenshots and photographs taken with another device cannot be blocked. One-time access does not mean the original image and every copy are immediately deleted.
One-time image tool
When a one-time image link helps
Use a view-once link when the recipient needs to inspect an image once and you do not want the same LOCK.PUB link to keep reopening it.
Keep the image out of chat history
Place a link in the conversation instead of attaching the image itself to the message thread.
Separate the link and password
Share the image link through one channel and deliver its password another way when the image is sensitive.
One-time image or ordinary photo message?
LOCK.PUB places the image behind a separate password and blocks another view through the link after the first successful unlock.

One-time image questions
What happens after the image is viewed once?
After the first successful password unlock displays the image, LOCK.PUB blocks later attempts to view it through that link.
Is the encrypted image deleted after viewing?
This tool promises one-time access, not deletion. The link stops revealing the image after the first successful view.
Can the recipient take a screenshot?
Yes. No browser-based view-once tool can reliably prevent a recipient from capturing the screen or photographing it with another device.
Which image formats can I upload?
You can upload JPG, PNG, GIF, or WebP. Guest and Free accounts accept images up to 1 MB, while Pro accounts accept up to 10 MB.
