PGP Encrypt
Encrypt a file using a PGP public key. Outputs ASCII-armored or binary ciphertext.
About PGP Encrypt
PGP Encrypt locks a file with someone's OpenPGP public key, so only the holder of the matching private key can open it. Use it when you need to send a document, archive, or secret to a specific recipient over email or any untrusted channel. It runs in your browser, so the plaintext is never uploaded anywhere during encryption.

Common uses
- Encrypt a sensitive contract or spreadsheet before emailing it to a colleague who published their PGP public key
- Send credentials or a config file to a recipient who can only be reached over an untrusted channel
- Produce ASCII-armored ciphertext you can paste directly into the body of an email or a ticket
- Encrypt a backup so it can sit in cloud storage that you don't fully trust
- Share a file with a journalist or maintainer who lists a PGP key for confidential tips
- Generate binary PGP output for a system that ingests raw .gpg files rather than armored text
Frequently asked questions
What kind of files can I encrypt?
Any file at all — the tool accepts every type, so documents, images, archives, and binaries all work the same way.
What's the difference between ASCII-armored and binary output?
ASCII-armored is text you can copy and paste (good for email bodies); binary is a compact .gpg-style file. Pick whichever the recipient's workflow expects.
Do I need the recipient's private key?
No — you encrypt with their public key, which they share openly. Only they can decrypt, using the private key they keep secret.
Is my file uploaded to encrypt it?
No. Encryption runs locally in your browser, so the original plaintext never leaves your device.
Can the recipient open this with standard PGP tools?
Yes. The output is standard OpenPGP, so GnuPG, Mailvelope, and other compliant tools can decrypt it.
