FAQ
Frequently asked questions
Do these tools send my input to a server?
The current tools are implemented client-side and do not require a backend for their core operations.

No. Base64 is an encoding format, not encryption. Anyone who has the encoded value can decode it.
Can I use these tools for testing work?
Yes. They are intended for common development and QA tasks such as formatting API data, generating test data and checking HTTP values.
