Tech & Web Utilities
Encoding, formatting, and text tools for everyday development and content work.
Overview
These are the small, specific utilities that come up constantly in web and content work — formatting JSON so it's readable, generating a QR code, encoding or decoding Base64 and URLs, checking password strength, generating a secure password, or diffing two blocks of text to see what changed. None of them are complicated on their own, but having them all in one place, free, and without installing a package or extension, saves real time.

How to Choose the Right Tool
These tools are largely single-purpose and self-explanatory by name — the main thing to get right is picking the encoding/format that matches what you're actually working with (Base64 vs. URL encoding vs. plain hashing are different operations with different use cases, not interchangeable steps).
At a Glance
| Tool | Use it for |
|---|---|
| JSON Formatter | Making minified or malformed JSON readable and validating its structure |
| Base64 Encode/Decode | Converting binary/text data to and from Base64 for embedding or transport |
| URL Encode/Decode | Safely encoding special characters for use inside a URL |
| Hash Generator | Generating a checksum/hash (e.g., for verifying file integrity) |
| Password Generator | Creating a strong, random password |
| QR Code Generator | Turning a link or text into a scannable QR code |
Common Mistakes to Avoid
- Treating Base64 encoding as encryption — it's a reversible encoding format, not a security measure; anyone can decode it back to the original text.
- Reusing a generated password across multiple accounts — a strong random password only helps if it's unique per account.
- Forgetting that URL-encoding is meant for specific unsafe characters, not the whole URL — encoding an entire URL (including "https://") will break it.
