How do I make a word cloud from text online?

Paste or upload your text into AnyTool Word Cloud Generator and a word cloud is drawn instantly, with each word sized by how often it appears. Choose a colour scheme, font, shape and rotation, then download the result as a PNG image or a crisp SVG vector. Everything runs in your browser, so your text is never uploaded.

  • Word size scales with frequency using an area-proportional (square-root) mapping
  • Hand-rolled spiral layout with bounding-box collision avoidance — no overlaps, no d3-cloud
  • Controls for max words, minimum frequency, stop-word removal, case and word length
  • Colour schemes, fonts, shapes (rectangle, wide, tall, square, circle mask) and rotation
  • Download as PNG or scalable SVG; seeded re-roll for reproducible layouts — 100% client-side

What is

Word Cloud

A word cloud (or tag cloud) is a visualisation in which words from a text are displayed at sizes proportional to how frequently they occur, so the most common terms stand out and reveal a document’s main themes at a glance.

Frequently Asked Questions

No upload happens. The cloud is built entirely in your browser, so your text never leaves your device and the tool works offline.

All tokenising, frequency counting, layout and rendering run locally in your browser using JavaScript and a canvas. Nothing is sent to a server, there is no tracking, and the page works offline after the first load — so you can safely visualise confidential surveys, feedback or drafts.

Each word is sized by how often it appears, scaled between a minimum and maximum font size so the most frequent words look largest.

AnyTool counts how many times each word occurs, then maps that count to a font size between your chosen smallest and largest sizes. It uses a square-root (area-proportional) scale, which is the convention good word clouds follow, so a word that appears four times looks about twice the area of one that appears once rather than four times the height.

Yes. You can download a high-resolution PNG or a true SVG vector built from the same placement, which stays sharp at any size.

The PNG export renders the canvas at twice the on-screen resolution for crisp images, while the SVG export rebuilds the exact same word placement as scalable vector text — ideal for posters, slides and print where you need it razor-sharp at large sizes.

Turn on “Remove stop-words” to drop common English filler words, and raise the minimum frequency or word length to hide rare or short words.

The generator can strip a built-in list of English stop-words such as the, and, of and to so the cloud highlights meaningful terms. You can also set a minimum number of occurrences, a minimum word length, ignore case to merge variants, and cap the total number of words shown.

Detailed Explanation

Methodology

How the Word Cloud Generator Works

AnyTool Word Cloud Generator builds the cloud entirely in the browser. It tokenises the text with a Unicode-aware regular expression, counts word frequencies, applies filters (case folding, stop-word removal, minimum frequency and length, and a maximum word cap), then maps each frequency to a font size using a square-root, area-proportional scale. Words are placed largest-first along a hand-rolled Archimedean or rectangular spiral, testing each candidate position against the bounding boxes of already-placed words so nothing overlaps.

  • Frequency counts reuse the same Unicode tokenizer as the Word Counter
  • Font size scales with the square root of frequency (area-proportional)
  • Placement uses an Archimedean or rectangular spiral with bounding-box collision tests
  • No d3-cloud and no external CDN — the layout is hand-rolled and runs locally
  • A seeded random generator makes every re-roll reproducible from the same seed
How It Works

Customisation and Export

The generator offers colour schemes, system font families, rotation modes (horizontal, vertical, mixed 90 degrees, or random tilt) with a rotation-percentage slider, and canvas shapes including a circular mask that confines words to an ellipse. Backgrounds can be transparent, white, cream, dark or navy. The result downloads as a high-resolution PNG rendered at twice the on-screen scale, or as an SVG rebuilt from the identical placement so it remains crisp at any size.

  • Eight colour palettes plus six font families to match any brand or slide deck
  • Rotation modes with an adjustable share of rotated words
  • Five shapes: rectangle, wide, tall, square and a circle mask
  • PNG export at 2× resolution; SVG export as scalable vector text
  • Adjustable font-size range, spacing and word cap
Privacy & Security

Privacy and Offline Use

Because every step — counting, layout and rendering — happens in the browser, the text never reaches a server, there is no account or tracking, and the page works offline after first load. Word clouds are popular for summarising survey responses, customer feedback, reviews, essays and presentations, and keeping that data on-device matters when it is confidential.
