Posted on vicspot.com — All tools run 100% in your browser. Zero data sent to any server.
As developers, we constantly switch between 10+ different tabs just to do basic tasks — format some JSON here, generate a password there, convert a hex color somewhere else. It's frustrating and slow.
I built
Counts words, characters (with and without spaces), sentences, paragraphs, and reading time — all in real time as you type.
When you need it:
- Checking if your blog post hits the 1,500-word SEO sweet spot
- Staying within Twitter's 280-character limit before posting
- Meeting essay word count requirements for academic submissions
- Estimating reading time for Medium or Substack articles
Paste text → instant results. No button click needed.
2. Text Case Converter
Generates placeholder text by words, sentences, or paragraphs. Choose count from 1 to 50, toggle the classic "Lorem ipsum..." opening phrase.
When you need it:
- Filling Figma or Adobe XD wireframes with realistic-looking text
- Populating a new WordPress theme demo before real content is ready
- Testing how your layout handles different paragraph lengths
4. String Reverse Tool
Beautifies, minifies, and validates JSON. Shows type info, key count, and byte size on validation. Clear error messages with exact parse errors.
When you need it:
- Debugging a compressed API response that's impossible to read as a single line
- Minifying a JSON config file for a production build
- Validating JSON before committing it to a config file
- Quickly checking if a JSON string is syntactically valid
# Before (unreadable):
{"name":"Alice","age":30,"skills":["JavaScript","Python","Go"]}
# After Beautify:
{
"name": "Alice",
"age": 30,
"skills": [
"JavaScript",
"Python",
"Go"
]
}
Common errors it catches: trailing commas, single quotes instead of double quotes, unquoted keys, comments (which JSON doesn't support), and invalid values like undefined or NaN.
6. Base64 Encoder / Decoder
Percent-encodes strings for safe use in URLs or decodes encoded URLs back to readable form.
When you need it:
- Building API query parameters that contain special characters
- Encoding a redirect URL that's embedded inside another URL as a parameter
- Decoding a percent-encoded URL from a log file to understand what was requested
- Debugging form submission values in GET requests
Before: https://example.com/search?q=hello world&filter=a&b
After: https%3A%2F%2Fexample.com%2Fsearch%3Fq%3Dhello%20world%26filter%3Da%26b
8. HTML Entity Encoder / Decoder
Generates MD5 checksums for any text string. Updates in real time as you type — no button click needed.
When you need it:
- Verifying a downloaded file's integrity by comparing checksums
- Generating cache keys from variable-length strings
- Deduplicating files by comparing their MD5 hashes
- Testing your own MD5 implementation against a known output
Input: "Hello, World!"
Output: 65a8e27d8879283831b664bd8b7f0ad4
⚠️ MD5 is not suitable for password hashing. Use bcrypt, Argon2, or scrypt instead. MD5 is fine for file checksums and non-security use cases.
🎨 CSS & Design Tools
10. Pixel ↔ REM Converter
Converts between HEX, RGB, HSL, and CMYK. Includes a visual color picker with live preview.
When you need it:
- A designer gives you a HEX code but your CSS uses HSL custom properties
- Converting a brand color from CMYK (print) to HEX (web)
- Generating color variations by adjusting HSL lightness and saturation
- Checking what a HEX color actually looks like before using it
/* Same color, all formats: */
HEX: #3498db
RGB: rgb(52, 152, 219)
HSL: hsl(204, 70%, 53%)
CMYK: cmyk(76%, 31%, 0%, 14%)
