Text tools earn their keep when they remove friction from writing, studying, shipping APIs, and small-business admin. You should not need a full IDE to pretty-print JSON, a crypto library install to hash a string, or a desktop publisher to turn notes into a PDF. This hub gathers GoToolsOnline’s keep-list text and developer utilities that we actively maintain for English-speaking users in the US, UK, Australia, Canada, and Europe.
Keep-list tools linked from here: Word & Character Counter, JSON Formatter/Validator, Base64 Encode/Decode, Hash Generator, Password Generator, Regex Tester, Text to PDF, and Invoice Generator. Related reading on the site includes the word-counter tool page itself at /tools/word-counter when you want the full guide beside the live counter.
Writing and academic limits
Admissions essays, scholarship statements, LinkedIn about sections, and X/Twitter drafts all enforce different ceilings. Word Counter reports words, characters, and related counts so you can trim with intent instead of guessing. Paste the final paragraph into the counter before you submit to a portal that silently truncates.
When a professor or editor wants a PDF of plain notes, convert with Text to PDF rather than screenshotting a Word window. If you later need that PDF merged with a cover sheet, jump to Merge PDFs on the PDF hub.
Developer and data chores
JSON Formatter pretty-prints and validates payloads before you paste them into tickets, config repos, or support chats. Invalid JSON fails fast with an error instead of a silent parse bug in production. Pair it with Base64 when you are debugging data URIs, basic auth header experiments on local fixtures, or embedded small assets in JSON (keep secrets out of public pastes).
Hash Generator helps with checksum-style checks (for example confirming two downloads match) using common algorithms such as MD5 and SHA-256. Hashes are one-way: they verify integrity; they do not encrypt content for confidentiality.
Regex Tester is for building and checking patterns against sample strings before you drop them into application code, log pipelines, or find-and-replace jobs. Start with small fixtures that include edge cases (empty strings, Unicode, newlines) so you do not discover mismatches only in production.
Security hygiene for everyday accounts
Use Password Generator to create long, random passwords for new accounts, then store them in a password manager. Prefer length and uniqueness over clever substitutions on a single dictionary word. The generator is a convenience utility—not a full identity platform—and generated values appear in your browser session like any other form field, so avoid using it on a shared screen during a live stream.
Small-business text output
Invoice Generator helps freelancers and micro-businesses produce a clean invoice PDF-style document without standing up accounting software for a one-off bill. Double-check tax lines and bank details before you send. For multi-page packs (invoice + terms), create the invoice first, then use PDF merge tools if you already have terms as PDF.
Browser-side vs request-scoped processing
Many pure text utilities (counting, formatting, encoding, hashing, regex against pasted samples, password generation) are designed to run in your browser so the text you paste need not be stored as a server-side archive. File-oriented neighbors such as Text to PDF still follow the site’s upload model: processed for the request over HTTPS and discarded afterward. Read each tool’s on-page copy for the accurate mode—we intentionally avoid absolute “never uploaded” claims for tools that must send a file to produce a download.
Suggested pairings
Draft → Word Counter → Text to PDF → optional Compress PDF. API debug → JSON Formatter → Base64 → Hash Generator. Pattern building → Regex Tester with fixtures saved in your notes. New account setup → Password Generator into your manager. Client billing → Invoice Generator.
Cross-hub links stay on keep-list pages only: PDF cluster at PDF tools, visuals at Image tools, QR/color/thumbnails at Media tools. That keeps this text pillar focused on copy, data, and lightweight developer chores rather than diluting into unrelated utilities.
Classroom, hiring, and documentation patterns
Teachers and teaching assistants often need quick counts for assignment caps and clean PDFs of feedback notes—Word Counter plus Text to PDF covers that path without a full office install on a lab computer. Hiring managers comparing cover letters can skim character counts when a form field is strict. Engineers documenting APIs should keep a validated JSON example beside prose so onboarding docs stay copy-paste accurate.
When you hash release artifacts, record both the algorithm and the digest in the same README line so future you does not guess whether a string is MD5 or SHA-256. When you test regex for input validation, include deliberately hostile samples (extremely long strings, emoji, RTL marks) so patterns fail closed in ways you expect.
Invoice Generator users should treat the tool as a document starter: verify legal entity name, address, and tax registration against your own records. For recurring clients, export consistently named files and archive them with your bookkeeping—not only in browser downloads.
Tips for trustworthy results
Do not paste production secrets into public computers or shared demos. Clear the form when you finish on a borrowed laptop. For regex, prefer readable patterns with comments in your codebase even if the tester holds a compact form. For JSON, keep a canonical pretty-printed copy in version control and minify only at the build or transport layer when required.
These keep-list tools are free, login-free, and ad-supported. We do not invent benchmarks or testimonials on this page—just practical guidance you can verify by using the tools yourself.

FAQ
- Are text tools really free?
- Yes. Keep-list text and developer tools are free with no account required.
- Is my text stored?
- Most paste-based text utilities run in your browser for the session. File-based tools process uploads for the request over HTTPS and discard them afterward.
- What can I do with the word counter?
- Count words, characters, and related metrics for essays, meta descriptions, and social limits.
- Does the JSON formatter validate?
- Yes. It pretty-prints and reports invalid JSON so you can fix errors before shipping payloads.
- Is the password generator safe to use?
- It creates random passwords locally in the tool UI. Prefer a password manager for storage, and avoid generating passwords on a shared live display.
