Text Tools

13 tools

Case conversion, whitespace cleanup, duplicate removal, counting, reversing, diffing, extracting, splitting, Markdown and accents — the full text workbench.

CASE

Case Converter

UPPERCASE, lowercase, Title Case, Sentence case and tOGGLE — applied live as you type.

Convert now → CLEANUP

Remove Extra Spaces

Collapse double spaces, trim line edges, strip tabs and blank lines in one pass.

Clean now → DEDUPE

Remove Duplicate Lines

Keep the first occurrence of every line — case-insensitive matching optional.

Sort Lines Alphabetically

Alphabetize A–Z or Z–A, or flip the whole line order — locale-aware sorting.

Sort now → WRAP

Add Prefix & Suffix

Wrap every line in quotes, commas, tags or markers — skip-empty option included.

Wrap now → COUNT

Character Counter

Live counts for characters, words, lines, sentences and paragraphs as you type.

Count now → REVERSE

Reverse Text

Flip characters, mirror words, or reverse line order — three modes, live output.

Reverse now → DIFF

Text Difference Checker

Compare two texts line by line — removals in red, additions in green.

Compare now → EXTRACT

Extract URLs & Numbers

Pull URLs, phone numbers, decimals or digits out of any messy text.

Extract now → SPLIT

Split Text

Break comma, pipe or custom-delimited strings into one clean item per line.

Split now → MD ↔ HTML

Markdown to HTML Converter

Two-way conversion: Markdown to clean HTML tags and back — drafts stay local.

Convert now → ASCII

Remove Accents

café becomes cafe, Straße becomes Strasse — Unicode-correct diacritic stripping.

Strip now → FILLER

Random Text Generator

Fresh lorem ipsum style paragraphs for mockups, layouts and CMS testing.

Developer & Encoding Tools

11 tools

Hashing, encoding, unique IDs and network math — the developer utilities you Google twice a week, computed locally.

MD5

MD5 Hash Generator

Instant 32-character digests, computed locally — uppercase and lowercase output.

Hash now → SHA256/512

SHA256 Hash Generator

Modern secure hashing — switch between SHA-256 and SHA-512 in one dropdown.

Hash now → PASSWORDS

Bcrypt Hash Generator

Properly salted password hashes with adjustable rounds — plus a verify panel.

Hash now → BASE64

Base64 Encoder & Decoder

UTF-8 safe encoding — emoji, Chinese and accented characters round-trip perfectly.

Encode now → PERCENT

URL Encoder & Decoder

Percent-encode text for query strings, or decode the %20 garble back to readable.

Encode now → UUID

UUID Generator

Cryptographically random UUID v4 values — one at a time or in bulk up to 100.

Generate now → MAC

MAC Address Generator

Random MACs with vendor prefix and local-bit control, plus a 4-format parser.

Generate now → NETWORK

Subnet Calculator

Network, mask, wildcard, broadcast and host range from any IPv4 + CIDR.

Calculate now → IP ↔ DEC

IP to Decimal Converter

IPv4 to decimal, hex and binary — and stored decimals back to dotted form.

Convert now → BASES

Binary Converter

Any base in, all bases out: binary, octal, decimal and hexadecimal side by side.

How It Works — Three Easy Steps

No manual, no install, no account. Paste, click, copy.

  1. Pick your tool. Text workbench or developer utilities — each tool does one job and shows how it does it.
  2. Paste your text or values. Sensible defaults are pre-filled, live previews update as you type, and nothing is ever sent anywhere.
  3. Copy the result. One-click copy buttons on every tool — done in seconds.

Frequently Asked Questions

Are these text and developer tools free?

Yes. All 24 tools are completely free with no trial, no account, and no usage limits. They run directly in your browser.

Is my text uploaded to a server?

No. Every operation — hashing, encoding, converting, comparing — runs locally in your browser. Your text never leaves your device.

Are the generated hashes and UUIDs safe for production?

Yes. Hashes come from a standard crypto library and UUIDs from your browser's cryptographic random source — the same quality production systems use.

Why Local Processing Matters

  • Privacy by architecture. Passwords, draft content, and internal data can't leak from a server that never receives them.
  • Speed. No upload round-trips — results appear the moment you click.
  • Availability. The tools work offline once the page has loaded.

Pick a Tool, Paste, Done
