Match the encoding to the receiving system
Tool Factory groups Base-N, URL, character, and escape operations into one connected collection. Canonical routes, task labels, and related links help users select the required representation without treating encoding as encryption.
| Method | Purpose | Important boundary |
|---|---|---|
| Base16, Base32, or Base64 | Represents binary data with a restricted text alphabet. | Alphabet, padding, and variant rules must match the receiver. |
| Percent-encoding | Represents octets inside a URI component. | Reserved delimiters have structural meaning and need component-aware handling. |
| Character encoding | Maps Unicode text to bytes or decodes bytes into text. | The sender and receiver must agree on the encoding and error policy. |
| Unicode normalization | Converts equivalent character sequences into a selected normalized form. | It does not make different words or scripts equivalent. |
| Encryption | Protects confidentiality with cryptographic keys. | It is a security operation, not an encoding method. |
How to complete this task
- Identify the receiving field. Determine whether the destination expects text, bytes, a URL component, or a named Base-N format.
- Confirm the exact variant. Check alphabets, padding, line breaks, byte order, and character encoding requirements.
- Use a small known sample. Encode and decode a short value whose expected bytes are known.
- Process the real input. Run one transformation and preserve the original until verification succeeds.
- Verify a round trip. Decode the result and compare bytes when the workflow must be reversible.
Common use cases
Binary data in a text field
Use the exact Base-N variant required by the protocol or file format.
Values inside URLs
Encode only the target component so URI separators retain their structural purpose.
Legacy text import
Decode bytes with the correct character encoding before cleaning or converting the text.
Evidence and standards
- RFC 4648: RFC 4648 defines Base16, Base32, Base64, padding, canonical behavior, and URL-safe Base64.
- RFC 3986: RFC 3986 defines URI syntax and percent-encoding for octets that conflict with component rules.
- WHATWG Encoding Standard: The web encoding standard defines browser decoding behavior and supported legacy encoding labels.
- RFC 3629: RFC 3629 defines UTF-8 as a transformation format for Unicode characters.
- Unicode Standard Annex 15: Unicode Standard Annex 15 defines the NFC, NFD, NFKC, and NFKD normalization forms.
Important limits
- Encoding does not hide confidential data from anyone who knows the format.
- A successful decode does not prove that the content is safe or authentic.
- Changing character encodings can replace or corrupt characters when the source encoding is wrong.
