FAQ Frequently Asked Questions

What encoding methods are available?
The tool supports ROT13, ROT47, Caesar Cipher (with custom shift values), Atbash cipher, Base64 encoding, and text reversal. Each method serves different purposes from simple obfuscation to data encoding.
Can I decode text if I do not know the encoding method?
The tool provides real-time preview for all methods, making it easy to try different decoding options until you find readable text. Most common encoding methods can be identified through trial and the preview feature.
Is this suitable for actual security or encryption?
No, these are encoding and simple cipher methods, not secure encryption. They are suitable for puzzles, basic obfuscation, or educational purposes, but should never be used to protect sensitive information.
What file formats can I upload?
The tool supports text files, CSV, and other common text-based formats through drag-and-drop upload. This makes it easy to process existing files without copy-pasting large amounts of text.
Does it keep a history of my encoding operations?
Yes, the tool maintains a local processing history so you can quickly revisit recent encoding/decoding operations. This history is stored locally in your browser and never shared or transmitted.
