Encrypt PNG Files Online in Your Browser

Why teams protect PNG images

People use this route when they want to encrypt PNG files online and keep design assets out of generic file-sharing workflows.

When Cryptvert is better than native protection

PNG files do not have a native password standard. Cryptvert is better when you want to secure screenshots, logos, and transparent assets without converting them to another format.

Best for

• Design teams sharing logos or UI exports with clients
• Screenshots that reveal internal tooling or account data
• Brand assets sent to contractors or external vendors

Not for

• Asset optimization or image conversion
• Collaborative design review inside the vault package
• Cases where the file is actually JPG, WEBP, or SVG

Common use cases

• Vault screenshots before posting them in external systems
• Protect brand assets during contractor handoffs
• Encrypt lossless design exports prior to archival

Mistakes to avoid

• Assuming the route changes PNG transparency or compression
• Using the PNG page for vector files that belong on /svg/encrypt
• Skipping a separate password channel when sharing the result

What does the PNG encrypt route actually do?

Cryptvert wraps the original PNG image inside an encrypted .vault package in your browser. It does not apply a native PNG password format to the file itself.

Does Cryptvert preserve PNG transparency?

Yes. The original PNG file is preserved inside the vault, so transparency and image fidelity stay with the source file.

Can I use this for screenshots and logo exports?

Yes. PNG screenshots, logos, and other lossless image assets are common use cases for this route.

Does decryption return the original PNG?

Yes. The decrypt route restores the same PNG file you wrapped during encryption.
