How to choose and use browser-based tools
A small browser tool can save time when you need one clear result: a word count, a different text style, readable JSON or a random password. Choosing the right tool also means understanding how it counts, converts and handles your input.
Pick a tool for the task
Checking a draft
Use Word Counter for word targets and live counts. A paragraph is a block separated by blank lines, while a line is separated by a line break. An emoji may contain several Unicode code points while appearing as one character, so use the count that matches your writing requirement.
Changing text style
Use Text Case Converter for uppercase, sentence case or names for code. For example, HTTPServer version2Value becomes http_server_version2_value in snake_case. Review names and acronyms after changing writing styles; automatic capitalization does not know which words are proper names.
Reading or checking JSON
Use JSON Formatter to format or validate a payload. The formatter preserves exact number tokens, so an identifier such as 9007199254740993 remains unchanged. A duplicate property warning deserves attention: different applications can interpret repeated property names differently.
Generating a password or passphrase
Password Generator creates random character sequences. Passphrase Generator creates word sequences, with six EFF-list words as its default. Generate a fresh result rather than copying a published example, and save it in your password manager.
Check the result before using it
- Read the tool’s rules and limits. Formatting a code name does not guarantee a valid identifier in every language.
- Compare the original and output. Look for lost characters, unexpected spacing or warnings.
- Use a small representative example before processing a larger draft or file.
- For work with exact identifiers or number values, confirm that formatting preserves the original tokens.
Check how data is handled
The five tools linked above process their inputs in your browser and do not submit their drafts or generated values. This is a property of those reviewed tools, not a promise about every service on the site.
Other tools may use external services, and some website pages load advertising or third-party assets. Page requests are counted for the admin overview. Contact messages are sent to the website. Read the relevant tool’s guidance and the privacy policy before entering confidential information.
Common questions
Do I need to install software?
The linked tools run in a modern browser. Their functionality still requires JavaScript and support for the browser features used by each tool.
Can I use the tools offline?
Some operations run locally after the page has loaded, but the website is not an installed offline app. Opening or reloading a page may require a connection, and external-service tools require network access.
Why do two word counters give different results?
Tools can use different definitions of a word or character. Check how each handles punctuation, languages, numbers and emoji, then follow the counting rules required for your task.
Will a formatted JSON file be smaller?
Readable indentation usually adds whitespace. Compact output removes unnecessary whitespace while keeping the JSON tokens. Choose the output style that fits the next step.
