## Guides and help pages

- [Compare byte sequences and keep valid work on a refusal](https://help.smartfact.ai/octetbench/guides/compare-and-refuse): Find one changed byte and see why malformed input cannot silently overwrite the current buffer.
- [Decode Base64 and read the text](https://help.smartfact.ai/octetbench/guides/decode-base64): Separate the byte representation from text encoding when reading an encoded order reference.
- [Make and undo an explicit byte edit](https://help.smartfact.ai/octetbench/guides/edit-bytes): Replace one byte, restore the original buffer and download its exact binary contents.
- [See characters and their exact bytes](https://help.smartfact.ai/octetbench/guides/hidden-characters): Inspect a UTF-8 character and Windows line ending without allowing the browser to normalise the original bytes.
