Every utility you need, in one place.

Strong, random passwords at any length

The strongest passwords are long and unpredictable, so the tool gives you full control over both. Drag the length slider to whatever a site requires — a quick 8-character code, a solid 12-character password, or a future-proof 16-character password — and toggle lowercase, uppercase, numbers, and symbols independently. This random password generator guarantees at least one character from each class you pick, so the result always passes strict complexity rules. Go beyond most generators with minimum digit and symbol counts, an option to avoid sequences like abc or 123, a field to exclude any characters a site rejects, an "exclude look-alikes" toggle for confusable characters like 0/O and 1/l/I, and a Pronounceable mode for easy-to-say passwords. A live strength meter shows the entropy in bits and crack-time across realistic online and offline attack scenarios, turning vague advice about "strong passwords" into a number you can see.

Passphrases, PINs, and memorable options

Not every password should be a wall of symbols. Switch to passphrase mode and it becomes a password generator with words, stringing together random terms from the 7,776-word EFF diceware list to produce something like Forest-Maple-Cobalt-7 — strong enough for a master password yet easy to remember and type. Choose the number of words, the separator, capitalization, and whether to add a number. A dedicated PIN mode produces numeric codes for phones, cards, and locks, and turning symbols off gives you a clean alphanumeric password or Wi-Fi key for routers and sites that reject special characters. Whatever style you choose, it's generated with the same bias-free randomness.

How strong does a password need to be?

As a rule of thumb, eight characters is no longer enough on its own, twelve is a reasonable minimum for everyday accounts, and sixteen or more is the sweet spot security experts now recommend — a random 16-character password has so many possible combinations that brute-forcing it is effectively impossible. Passphrases reach the same level of safety through length rather than symbols: five or six random words are both highly secure and far easier to recall than a scrambled string. Because the generator shows entropy and crack-time live, you don't have to guess — just lengthen the password until the meter reads "very strong" and you'll know it's beyond the reach of offline attacks.

A private, free alternative to built-in generators

Most password generators live inside a product — the ones built into LastPass, Bitwarden, 1Password, Norton, or Chrome only appear once you're signed in. This is a free online password generator that's open to everyone, with no account and no lock-in: mint a password here, then store it in whichever password manager you prefer. It runs entirely client-side, so it keeps working offline and never logs or transmits what it creates, and an optional clipboard auto-clear wipes a copied password after 45 seconds. For bulk work, generate up to 100 unique passwords at once and download them as a text file. However you use it, the golden rules stay the same: make passwords long, and never reuse them across sites.

Custom QR codes with your logo and colors

Make the code your own. As a custom QR code generator, it lets you recolor the dots and background to match your brand, adjust the size and quiet margin, and overlay your own image to produce a QR code with a logo in the center. QR codes carry built-in error correction, so a sensible logo doesn't stop them scanning — and you can raise the error-correction level when you place a larger mark or expect the code to be printed small. A live preview shows exactly how the finished code looks before you download it, so what you design is what you get.

URL, Wi-Fi, vCard, and more

Encode whatever you need: a URL or link, plain text, an email address, an SMS message, a contact card (vCard), or a Wi-Fi login. A Wi-Fi QR code stores the network name, password, and security type, so guests connect by scanning instead of typing — ideal for cafés, offices, events, and guest rooms. A vCard code drops your name, phone, and email straight into someone's contacts after a single scan. Download the result as a crisp vector SVG that scales cleanly to poster or billboard size for print, or a PNG at the resolution you choose for screens and the web.

Static codes that never expire

A static QR code (what this tool makes) stores its data directly, so it's free, never expires, and isn't tracked; the trade-off is that you can't edit it after printing. A dynamic QR code points at a changeable short link and logs scans, but it needs an account and usually a paid plan, and it stops working if that service shuts down or the subscription lapses. For most uses — sharing a link, a menu, contact details, or Wi-Fi — a static code is the better, safer choice, and the only kind that stays genuinely free with no expiration.

A free alternative to Canva, Adobe, and Google

Most QR generators live inside another product — the ones in Canva and Adobe Express only appear once you're signed into their design apps, and Google has no dedicated public QR tool. This is a free QR code generator with no sign up that's open to everyone: make a branded, custom code with a logo, then download it as PNG or SVG at no cost. It runs entirely client-side, so it keeps working offline and never logs or transmits what you create — a fast, private, and genuinely free way to generate every QR code you need.

Character count with and without spaces

Different platforms count differently, so this character counter shows characters including spaces and characters excluding spaces at the same time. When a form caps every keystroke, you have the with-spaces number; when it counts only visible letters, you have the without-spaces number — no guessing which total a site is using. Select part of your text and the stats update for just that selection, handy for checking a single paragraph, heading, or quote without touching the rest of your draft.

Built for essays, SEO, and social limits

Use it as an essay word counter to hit an assignment's word limit exactly, or as an SEO helper to keep meta titles and descriptions in range. Built-in presets flag common limits as you approach them — the 280-character Twitter/X limit, Instagram caption and bio lengths, and SMS message segments — so it doubles as a social media and SMS character counter that warns you before you run over. Because the count is live, you can write right up to a limit and watch the number turn as you cross it.

Keyword density and readability built in

Beyond counting, it helps you improve what you've written. Keyword density shows how often each word and phrase appears relative to your total word count — useful for SEO and for spotting repetition — and it reports both single words and multi-word phrases. The Flesch readability score rates how easy your text is to read on a 0–100 scale, turning a simple counter into a lightweight writing checker you can keep open beside whatever you're drafting.

Live counts, reading time, and selection stats

Everything updates the instant you type or paste, with no button to press. As well as the running word count and character count, you get sentence and paragraph totals and an estimate of how long the text takes to read and to speak aloud — useful for sizing a speech, a script, or a blog post. Highlight any portion and the counts switch to that selection, so you can measure a single heading, paragraph, or quote in place. Your text is auto-saved locally too, which means closing the tab won't lose your draft and reopening the page brings it straight back — all without anything ever leaving your device.

A free alternative to Word, Docs & Grammarly

There's already a word counter buried inside Microsoft Word, Google Docs, Grammarly, and QuillBot — but each means opening a document, signing in, or pasting into a bigger app. This is a standalone word counter tool: one page, no login, instant results, and extras those built-in counters don't show. It works for any language, counting Chinese and Japanese characters individually where word boundaries don't apply, and it auto-saves your text locally so it's still there when you return. For a fast, private, and free count, it's the simpler choice.

Convert HEX, RGB, HSL, HSV, CMYK, and OKLCH

Every field is two-way. Edit the HEX code and the RGB, HSL, HSV, CMYK, and OKLCH values update instantly; change any one of them and the rest follow. That makes it a quick hex to rgb color converter, an rgb to hex tool, an rgb to CMYK converter, and an HSL converter in a single view — paste a hex code from a design file and copy back whichever format your stylesheet, app, or print job expects. It even names the nearest CSS color, so a custom shade is always easy to describe.

Pick a color from an image or your screen

Need the exact color from a photo, logo, or screenshot? The color picker from image lets you upload, drag and drop, or paste a picture, then click any pixel to grab its color — with a magnifier loupe for pixel-perfect accuracy. The image is read locally and never uploaded, so this image color picker works in every browser. Prefer to grab a color elsewhere on screen? The eyedropper samples any pixel in Chrome and Edge, the native color wheel lets you drag to a shade, and a recent colors strip remembers what you've used.

Color schemes, contrast, and accessibility

Turn one color into a whole palette. The tool builds color schemes from the color wheel — complementary, analogous, triadic, tetradic, split-complementary, and monochromatic — so it doubles as a color palette generator. Accessibility is built in: the WCAG contrast checker rates your color against white, black, or any custom background with AA/AAA badges, the tints and shades scale gives you lighter and darker steps, and a color blindness preview shows how your color looks to people with protanopia, deuteranopia, tritanopia, and achromatopsia.

A free alternative to the Google and Adobe color picker

Most color pickers are buried inside something bigger — the Google color picker only appears in a search result, and the Adobe color picker lives inside Photoshop or Illustrator. This is a standalone free color picker and converter that opens in one click, works on any device, and never asks you to sign in. Whether you're a developer matching a brand hex color, a designer fine-tuning an HSL palette, or you just need to convert one code to another, it's a fast, private color picker tool that does the job and keeps your work on your own machine.

GitHub-Flavored Markdown, rendered live

The previewer speaks GitHub-Flavored Markdown (GFM), so tables, task lists, strikethrough, syntax-highlighted code blocks, and autolinks render the way they do in a GitHub README. A generous formatting toolbar adds bold, italic, strikethrough, inline code, headings, lists, task lists, quotes, links, images, tables, and dividers with one click, and keyboard shortcuts (Ctrl+B, Ctrl+I, Ctrl+K, Ctrl+F) work just like a desktop editor. A live word, character, and reading-time count sits in the toolbar, an auto table of contents is built from your headings, and the editor and preview scroll in sync — so this Markdown to HTML preview keeps you oriented even in a long document.

Mermaid diagrams, LaTeX math, and highlighted code

This is where it pulls ahead of most free previewers — and of VS Code's built-in preview, which can't do any of it without extensions. Drop a ```mermaid block and your flowchart or sequence diagram renders live as an SVG that follows light or dark mode. Write inline $E = mc^2$ or a $$…$$ block and the LaTeX math is typeset instantly with KaTeX. Fenced code is colored by highlight.js in a GitHub-style theme. The heavy renderers load only when your document uses them, so plain text stays fast — a Markdown preview with Mermaid support and math that normally means installing an extension or signing up for a web app.

A no-install alternative to the VS Code Markdown preview

If you normally reach for the VS Code Markdown preview (Ctrl+Shift+V) or a vs code markdown preview side-by-side split (Ctrl+K V), this page does the same job without opening an editor or installing anything. The same goes for an atom markdown preview, the vim and nvim markdown-preview plugins, or the built-in zed markdown preview — all give you a rendered split view, and so does this tool, in any browser, with nothing to configure. Paste your Markdown and you have a working markdown preview online in seconds.

Export to PDF, HTML & Markdown — and share with a link

When a document is ready, take it anywhere. Export to PDF prints the rendered page — diagrams, math, and highlighted code included — with no flaky plugins; Download .html saves a self-contained web page; and Download .md keeps the source. Copy the clean rendered HTML, or copy it as rich text to paste fully formatted into Gmail, Google Docs, or Notion. And Share encodes the whole document into the link itself, so sending it needs no account and no server — nothing is uploaded, a privacy win cloud editors like StackEdit and HackMD can't match.

Private by design, fast by default

Previewing Markdown you didn't write shouldn't be risky, so the tool sanitizes the rendered HTML with DOMPurify, stripping script tags, inline event handlers, and javascript: URLs. Everything runs in your browser: open an existing .md, .markdown, or .txt file, paste or drag in an image to embed it, switch to fullscreen or find & replace, and your draft is auto-saved locally so closing the tab won't lose your work. No sign-up, no upload, no tracking — for drafting docs, previewing a README before you push it to GitHub, rendering Mermaid and math, or converting Markdown to clean HTML and PDF, it does the whole job in one fast, private page.
