10 Free Browser-Based Text Tools Every Developer Should Bookmark

As developers, we constantly deal with text transformation tasks —
encoding a string, cleaning up CSV data, converting between formats.
Most of us either Google a Stack Overflow answer, write a throwaway
script, or paste sensitive data into some sketchy online tool.

There's a better way.

I've been using TextTooling.com for these
tasks. Everything runs 100% in the browser — no data is sent to any
server. Here are the tools I reach for most often:

1. URL Encoder / Decoder

Stop manually escaping query string parameters. Paste your string,
get the encoded version instantly.

2. Base64 Encoder / Decoder

Useful when debugging JWTs, API payloads, or image data URIs.

3. HTML to Text Converter

Strip all HTML tags from a string — great for cleaning scraped content
or sanitizing user input before logging.

4. Remove Duplicate Lines

Pasting a list of IDs or values and need to deduplicate?
This handles it in one click.

5. Sort Lines

Alphabetically sort any list — useful for normalizing imports,
config values, or enum entries.

6. Whitespace Remover

Trim extra spaces, tabs, and blank lines from messy text or
copy-pasted content from PDFs and docs.

7. Word / Character Counter

Quick sanity check on string lengths before hitting API limits
(OpenAI, Twitter, SMS gateways).

8. Comma to Column / Column to Comma

Convert CSV data to a vertical list and back. Saves time when
preparing SQL IN clauses or Excel imports.

10. Remove Line Breaks

Paste a paragraph from a PDF that came in with hard line breaks
after every 80 characters. One click fixes it.

Why browser-based matters

Most online tools send your input to a backend server. That's fine
for public data, but not ideal when you're pasting:

  • API keys or tokens (even partial ones)
  • Customer data or PII
  • Internal config values
  • Proprietary code snippets

With client-side tools, the data never leaves your machine.
No logs, no storage, no risk.
