Developer Tools

TextGround's developer tools cover the everyday tasks that developers encounter: formatting messy JSON before committing it, encoding a string for a URL, generating a hash to verify a file, or producing a UUID for a new database row. Every tool runs instantly in your browser — paste input, get output, no round-trip to a server.

All tools process data locally. Nothing you paste is sent to TextGround's servers.

Frequently Asked Questions

Is Base64 encoding the same as encryption?

No. Base64 is an encoding scheme for transporting binary data as text — anyone can decode it immediately. It provides no confidentiality. Use a hash (SHA-256) for integrity checks and bcrypt for password storage.

Which hash should I use for passwords?

Use bcrypt (or Argon2/scrypt) for passwords — these are intentionally slow, salted key-derivation functions designed for password storage. MD5 and SHA are fast hashes for checksums and data integrity; they are not safe for password storage because they can be brute-forced rapidly.

Do these tools send my code or data to a server?

No. All formatting, encoding, hashing, and generation runs in your browser tab. Nothing you paste or type is transmitted to TextGround's servers.

What is the difference between URL encode and Base64 encode?

URL encoding (percent-encoding) converts characters that are not safe in a URL into a %XX hex escape — used in query strings and paths. Base64 encoding converts binary data (or any bytes) into a safe ASCII string — used in data URIs, email attachments, and API tokens. They solve different problems.
