Toolora

Everyday utilities in one place

Free browser tools to format JSON, SQL, and XML, decode JWTs, convert YAML and CSV, generate QR and barcodes, check passwords, and run calculators. Search below or pick a category. Most utilities process input on this device — no signup. Currency conversion is the exception: it reads a public exchange-rate feed, not your identity.

JSON 6 tools

Format, minify, validate, compare, generate sample JSON, and turn a payload into TypeScript interfaces. These pages share a persist key where noted so you can Convert to a sibling without re-pasting. Invalid JSON is reported, not silently “fixed.”

Developer 19 tools

JWT inspect and sign, SQL/XML/HTML/CSS/JS formatters, YAML and CSV conversion, cron builder and explainer, regex tester, hashes, HMAC, timestamps, URL parser, and number bases. Built for pasted snippets, not for connecting to your production database.

Encoding 12 tools

Base64 and hex, HTML entities, URL encode/decode, color conversion, Markdown preview and HTML export, QR codes, barcodes, and image-as-data-URI. Encoding is not encryption — the pages say so when it matters.

Text 25 tools

Case family (including Title Case at the shipped /tools/capitalize path), slugify, word and character counts, sort, reverse, line numbers, find/replace, regex, diff, lorem, typing speed, and random pickers. Cleanup stays in the tab.

Password 3 tools

Generate a random password, score a candidate locally, hash or verify bcrypt, and mint UUID v4/v7 or ULID. Strength is a heuristic, not a breach database. Do not test production passwords on a shared machine.

Image 4 tools

Compress JPEG/PNG/WebP, resize with optional aspect lock, convert format, crop with a rectangle, or embed a small file as Base64. Pixels are read in the browser; there is no folder batch upload.

Calculators 15 tools

Percent and discount math, units, currency (public mid-market rates), age and working days, GPA, BMI, loan and compound interest, tip and margin, scientific keypad. Formulas and limits are on each article page.

Date / Time 5 tools

Time zone conversion with IANA names, Unix timestamp parse, stopwatch and laps, countdown, and Pomodoro. Timers are for this tab, not a server crontab — use Cron Builder for five-field schedules.

Popular tools

Start with the utilities people open most often — JSON Formatter, SQL Formatter, Base64, JWT Decoder, Password Generator, QR codes, and YAML ↔ JSON. Open any card for a live workspace with how-to copy and FAQ. The full directory is on All tools, grouped by category, with written guides at /guides.

JSON Formatter

Pretty-print JSON with indentation, optional key sorting, and minify. The result updates as you type.

SQL Formatter

Pretty-print SQL with clauses on their own lines. The result updates as you type.

Base64 Encode

Encode text to Base64 (UTF-8 safe). Type or paste below — the result updates as you type.

JSON → TypeScript

Generate TypeScript interfaces from a JSON object or array. The result updates as you type.

QR Code Generator

Create a QR code from a URL, text, Wi-Fi network, or contact details. The code updates as you type — nothing is uploaded.

JWT Decoder

Decode a JWT header and payload in your browser as you type. The signature is displayed but not verified. Invalid tokens are not saved.

Password Generator

Generate strong random passwords instantly in your browser. Free, private, and no signup required.

YAML ↔ JSON Converter

Convert YAML documents to JSON, or JSON values to YAML. The result updates as you type.

View all tools

Fast by default

Open a tool and type: formatters, converters, and most generators update as you go. There is no account wall for v1 utilities. You are not waiting on a queue or a paste-bin upload for JSON, SQL, or a JWT inspect.

Private by design

v1 utilities process data in this tab. JSON, tokens, passwords you generate, and images you compress are not posted to Toolora’s servers for those tools. Close the tab to drop the paste. Currency conversion fetches a public mid-market rate for the pair you choose.

Built for real work

The catalog covers JSON and YAML, JWT encode/decode, HMAC and bcrypt, SQL/XML/HTML formatters, URL and Base64, Markdown, QR and barcodes, case and slug tools, calculators, local image edits, CSS helpers, and timers — not a single “Swiss army” blob with no instructions.

How to find a tool

Use the search field on this page (or Ctrl+K / Cmd+K on the catalog) to match a name, description, or category — json, jwt, yaml, qr, bcrypt, slug, and similar queries work. Category cards open /tools/json, /tools/developer, /tools/encoding, /tools/text, /tools/password, /tools/image, /tools/calculator, /tools/time, and /tools/css. Each tool URL is stable: we do not rename a shipped /tools/{slug}.

Inside a tool, paste or type in the workspace. Article pages show a live result, privacy notes, examples, and FAQ. Written walks for the whole catalog are on /guides. Bookmark a tool URL if you return to the same workspace often — there is nothing to install.

What is in the catalog

JSON tools format, minify, validate, compare, and turn samples into TypeScript. Developer tools cover SQL and XML, YAML and CSV, cron, regex, hashes, HMAC, JWTs, timestamps, and number bases. Encoding covers Base64, hex, HTML entities, URLs, colors, Markdown, QR, and barcodes. Text tools change case, slugify, count, clean, diff, and pick random values. Calculators and date tools sit beside local image and CSS helpers. Open All tools when you want the full grouped directory instead of this homepage snapshot.

This homepage is a snapshot, not the full grouped catalog. The eight popular cards are the same live workspaces as All tools — not screenshots or demos. If you already know a slug, search instead of scrolling. If you are exploring, open a category then a card: each tool page has its own how-to, examples, and FAQ, so you are not reading one recycled paragraph on every URL. English is unprefixed; Vietnamese uses the same slugs under /vi/.

Why browser-based tools?

Many one-off utility sites ask you to paste sensitive snippets into a server form. Toolora focuses on client-side processing for v1 tools: JSON formatting, encoding, hashing, Markdown preview, image compress/resize, and similar utilities run in your browser. That means faster results, fewer round-trips, and a clearer privacy story for everyday debugging and writing. You can star favorites on this device without an account; sign in to sync them across browsers. Starring is optional and is not required to run a tool.

Prefer a guided walkthrough? Read the how-to guides or check the FAQ and Privacy Policy for how tools run locally, themes, and common questions.

Tip: Light mode is the default. Switch to Dark anytime from the palette icon in the header. English is unprefixed; Vietnamese lives under /vi/ with the same tool and guide slugs.
