Free Online Data Tools for Developers

Encode Base64, format JSON, calculate hashes and convert files with free browser tools. Choose a task, enter your data and copy or download the result.

Choose a task. Bring your data.

Serialize brings ready-to-use data tools together. Each page already defines the operation: paste text or open a file, adjust the relevant options and run it. There is no workflow to build and no account to create.

Read an encoded payload

Decode Base64, hex or URL escapes to inspect the underlying text or bytes. If the result is compressed data, continue with the matching decompressor.

Make structured data readable

Format JSON, inspect its structure, or convert CSV and YAML. Start with a published example to check delimiters and value types before using your own data.

Your input stays out of the catalogue

Tools run in your browser. Inputs and results are not published or saved in page URLs. HTTP and DNS tools send only the requests you choose to run. Star useful tools to keep them in this browser’s favorites.
