A mixed bag of everyday text jobs — counting, comparing, converting and generating. What they share is that all of them are done locally, which matters more than it sounds for two of them in particular: a password generator that sends its output over the network is not a password generator, and a document you are diffing may be confidential.
Which one do you want?
| If you are… | Use |
|---|---|
| Word or character count, reading time | Word Counter — live as you type. |
| A strong password | Password Generator — generated in your browser using the OS random number source. |
| A QR code for a link, wifi or text | QR Code Generator. |
| A long link made short | URL Shortener — the one tool here that does use a server, because shortening requires one. |
| Changing case, or naming conventions in code | Case Converter — camelCase, snake_case, Title Case and more. |
| Spotting what changed between two drafts | Diff Checker — line by line. |
| Unix timestamps | Timestamp Converter. |
Password length beats complexity: a long passphrase is far harder to crack than a short string of symbols you cannot remember. Generate it here, store it in a password manager, and never reuse it.
Small things that cause large problems
- Length beats complexity in a password. Each extra character multiplies the search space; swapping a for @ merely adds one guess to a list attackers already have. A long passphrase kept in a password manager beats a short unmemorable string of symbols.
- Word count depends on what counts as a word. Hyphenated compounds, numbers, and em-dashes are handled differently by different tools, so two counters can disagree by a few percent on the same text. Match the tool your submission is checked with.
- Naming conventions are not interchangeable. camelCase, snake_case, kebab-case and PascalCase carry meaning about where a name is used. Converting between them mechanically breaks acronyms unless the tool preserves them.
- Diffing works on what changed, not on what moved. A paragraph relocated intact often shows as one deletion and one insertion. Reading a diff means knowing what the algorithm is actually looking at.
Frequently asked questions
Are generated passwords safe to use?
Yes. They are produced by your browser's cryptographic random number generator, never transmitted, and never stored. Copy it straight into your password manager.
Does the word counter match Microsoft Word?
Very closely. Small differences appear around hyphenated words and numbers, where different tools make different judgement calls.
Why does the URL shortener behave differently from the other tools?
Because it has to. A short link cannot redirect anywhere unless the destination is stored on a server — it is the single exception on the site, and the privacy policy sets out exactly what is kept and for how long.
