Byte-Perfect Utility

Encode any file into a string and decode it back exactly.

Use Base64 payloads with file metadata so the restored file keeps the same bytes, name, and type.

Encode File -> String

Pick any file, enter your key, set max chars per chunk, then generate payload chunks.

Access key Max chars per chunk Encoded payload

Paste one or many payload chunks (or load from .txt), enter the same key, then decode.
