Word Counter, Case Converter and Base64: A Practical Guide to Everyday Text Tools
Most of us handle small text jobs every day: checking whether a paragraph fits a limit, fixing a headline typed in capitals, or making sense of a block of code someone pasted into a chat. None of these jobs deserves a heavy application. A few small browser tools do them in seconds, and when the tools run locally, your text never has to leave your device.
Counting words, characters and reading time
A word counter splits your text on whitespace and counts the pieces, which matches how most word processors count. Good counters also report characters with and without spaces, sentences and an estimated reading time. That mix of numbers matters because different places measure length differently.
| Content | Typical target |
|---|---|
| Meta description | About 150–160 characters |
| Tweet or X post | 280 characters |
| Blog post | Often 800–2,000 words, depending on the topic |
| College essay | Usually 250–650 words, set by the application |
| Speaking time | Roughly 130–160 spoken words per minute |
The speaking-time rule is useful for talks: a five-minute speech is around 650 to 800 words. Paste your script into the word counter and you will know in a moment whether to cut or expand.
Changing case without retyping
A case converter rewrites text in another style. Everyone knows UPPERCASE and lowercase, but the other styles are where it saves real time.
- Title Case for headlines and document titles.
- Sentence case to repair text that was typed with caps lock on.
- camelCase and snake_case for variable and column names in code and spreadsheets.
- kebab-case for URLs and file names, where hyphens are easier for search engines and people to read than underscores or spaces.
Base64: what it is and when you meet it
Base64 turns any data into plain ASCII letters, digits and a few symbols. It is not encryption and gives no secrecy at all; anyone can decode it. Its job is transport: it lets binary data travel through systems that only accept text, such as JSON fields, email attachments and data URLs.
You will meet it when you read a data URL in CSS, inspect a token or an API response, or embed a small image directly in HTML. The Base64 tab converts in both directions, so you can decode a suspicious-looking string to see what it contains before you trust it.
Making JSON readable
JSON from an API is often minified onto one line. A formatter adds consistent indentation and line breaks, and it validates the syntax at the same time, so a missing comma or a stray quote shows up straight away. For bigger jobs such as minifying or converting to CSV, use the dedicated JSON Formatter & Validator.
A simple cleanup routine for any text
- Paste the text into the counter to see where you stand against the limit.
- Fix the case if the style is wrong.
- Remove accidental double spaces and blank lines.
- Count again, then copy the result into your document or code.
Privacy when you paste text online
Text often contains names, addresses, contracts or source code. Before you paste it into any web page, check whether the tool processes it on your device or sends it to a server. The tools on this page run in your browser using JavaScript, so nothing you type is uploaded. A quick test: load the page, disconnect from the internet, and see whether it still works.

Frequently asked questions
Is my text uploaded anywhere?
No. The text tools run entirely in your browser, so nothing you type is sent to a server.
How is word count calculated?
The text is split on whitespace and the pieces are counted, which matches most word processors. Hyphenated words count as one.
Is Base64 a way to hide information?
No. Base64 is an encoding, not encryption. Anyone can decode it, so never use it to protect passwords or private data.
Why would I format JSON?
Minified JSON on one line is hard to read. A formatter indents it and checks the syntax, which makes errors and structure easy to see.
Which case style should I use for file names?
Lowercase with hyphens, such as my-report-2026.pdf, is the safest choice for web use and works on every operating system.
