Generate UUID v4/v7 in batches and detect UUID versions.
Hash & File Checksum
Calculate MD5, SHA-1, SHA-256, SHA-384, or SHA-512 for text and files.
URL Parser & Builder
Inspect URL components, edit query parameters, and rebuild a normalized URL.
Cron Generator & Preview

Match the tool to your development task
Use JSON or SQL formatting to inspect data and queries. Base64 and URL encoding represent text for transport; URL Parser separates paths, parameters, and fragments.
JWT decoding shows token fields; HS256 verification requires an existing secret. Hash tools compare digests, and Cron preview shows schedules in a selected timezone. Check results against the rules of your application.
Before you choose a tool
- Base64 is an encoding and does not keep content confidential.
- Readable JWT content does not prove a valid signature or authorization.
- Some basic encoders send input to this server; see each page’s privacy details.
