Online URL Validator
Validate URLs, including common HTTP and HTTPS formats.
About this validator
This tool helps identify malformed URLs before they reach forms, APIs, integrations, or databases.
The check focuses on syntax and does not verify whether the destination exists, responds, or is safe.
Best practices
- Decide whether your use case requires absolute URLs or accepts relative ones.
- Normalize links before persisting or comparing data.
- Perform availability checks on the backend when you need to test real access.
Important notice
This tool validates only URL structure. It does not guarantee availability, reputation, or safety.
