Up to 2 GB. There is no password recovery. Encrypted files open only with this tool. Nothing is uploaded.
The key is derived with Argon2id (64 MiB, 3 passes) from a random salt; the file is sealed in 1 MiB AES-256-GCM chunks whose nonces and authenticated data bind each chunk’s position and the end of the file.
A 20 MB PDF encrypted with a six-word passphrase becomes report.pdf.pze, about 400 bytes larger, which only that passphrase can open.
