Encode & Decode

Converts any plain text or string input into Base64-encoded output, ready for embedding in JSON, emails, or data URIs.

Converts any uploaded file — images, PDFs, binaries — into a Base64-encoded ASCII string ready to embed in JSON, CSS, or HTML.

Takes a Base64-encoded string and decodes it back to the original plain text or binary content instantly.

Encodes plain text into Base32 format, producing an uppercase alphanumeric string safe for case-insensitive environments.

Reads a file's binary content and outputs its Base32 representation, useful for encoding small files in case-insensitive systems.

Decodes a Base32-encoded string back to its original text, reversing the 8-character-to-5-bit grouping used by the standard.

Percent-encodes special characters in a URL or query string so it can be safely transmitted over HTTP without misinterpretation.

Converts percent-encoded URL sequences back to readable text, turning %20 and similar escape codes into their original characters.

Escapes special characters like angle brackets and ampersands into HTML entities so the text renders literally in a browser.

Converts HTML entities such as &, <, and > back into their corresponding plaintext characters for reading or editing.

Transforms plain text into its binary (base-2) representation, outputting each character as an 8-bit sequence of 0s and 1s.

Reads a sequence of binary digits and converts the 8-bit groups back to the corresponding ASCII text characters.

Converts plain text to hexadecimal, representing each character as its two-digit hex code for debugging or data inspection.

Turns a hexadecimal string back into readable ASCII text by parsing each two-character hex pair as a single character.
