Explore categoryHow developer tools fit together
This is the smallest cluster on the site and it covers three everyday jobs: making JSON readable, moving data between text and Base64, and generating credentials that are actually random. All three run entirely in your browser, which is the point when the payload you are debugging contains real customer data or a live token.
One distinction is worth stating clearly because it causes real security mistakes. Base64 is an encoding, not encryption. Anything encoded in Base64 can be decoded by anyone, instantly, with no key. It exists to move binary data safely through text channels, not to protect it. If something needs to stay secret, it needs actual encryption.
The password generator uses the browser's cryptographic random number source rather than ordinary pseudo-randomness, and it never transmits or stores what it produces. Nothing generated here is logged, so a password only exists where you paste it.
Which developer tool do you need?
A JSON payload is unreadable or you suspect a syntax error
Format, minify, and validate with line and column feedback, plus a searchable tree view and key sorting.
JSON FormatterYou need to encode or decode Base64
Both directions in one place, for text, data URIs, config values, and tokens you need to inspect.
Base64 Encode & DecodeYou need a strong password or passphrase
Cryptographically random output with length, character set, and ambiguity controls, plus a strength estimate.
Password Generator
What these tools are, and what they are not
| Tool | What it is | Common misconception |
|---|---|---|
| Base64 Encode & Decode | A reversible text encoding for moving binary data through text channels | That it protects data. It does not: anyone can decode it with no key |
| JSON Formatter | A formatter and syntax validator | That it validates against a schema. It checks syntax, not whether fields are correct |
| Password Generator | A cryptographically random generator that runs locally | That generated passwords are stored or recoverable. Nothing is kept anywhere |
Common questions about developer tools
Is Base64 a form of encryption?
No, and treating it as one is a real security mistake. Base64 is a reversible encoding with no key: anyone holding the string can decode it instantly. Use it to transport data through text-only channels, never to keep a secret.
Is it safe to paste a real API payload or token here?
The processing itself is safe, because everything runs in your browser and nothing is transmitted or logged. The usual caution still applies to your own screen and clipboard, but the data never reaches a server.
Are the generated passwords random enough to use?
Yes. They come from the browser's cryptographic random source, not from ordinary pseudo-random numbers, and the tool shows an entropy estimate so you can judge the strength rather than guess at it.
Does the JSON formatter check my data against a schema?
No. It validates syntax and reports where the parse fails. Whether the right fields are present with the right types is a schema question, which is a separate concern.
Can I decrypt an MD5 or SHA hash?
No, and no tool can. Hashes are one-way by design: they are not encryption and there is no key that reverses them. What lookup services actually do is compare against precomputed lists of common inputs.
Why are there only three developer tools?
Because we publish tools that are tested and complete rather than filling the category out. The cluster is being expanded deliberately, and the tool status page lists what is live today.
