Word Cloud Generator

A word cloud draws the words of a text at sizes that match how often they appear, so the main themes of survey answers, customer reviews, a speech or an essay stand out at a glance. Paste text and the tool counts the words for you, or paste your own “word, weight” list. The layout, colours and image are made in your browser; nothing is uploaded.

How to use this tool

1. Paste your text, or switch to “word, weight” lines such as “service, 42”.
2. Leave out common words (the, and, of…) and any words you add to the exclude box.
3. Pick a maximum number of words, a shape, word direction, colours, background and font.
4. Press Calculate, then download the PNG image or the SVG vector file. Change the layout seed for a new arrangement.

Formula

Font size = largest size × √(count ÷ highest count), never below the minimum size

The square root keeps the most frequent word from dwarfing everything else: a word used a quarter as often is drawn half as big. The largest size is 20% of the image’s shorter side for clouds of up to 30 words and shrinks (to no less than 8%) for bigger clouds; if the words would still cover more than half of the shape, every size is scaled down by the same factor. Words are placed from the most frequent outwards along an Archimedean spiral from the centre; each word’s letter shapes are checked on a 4-pixel grid so words can nest closely without overlapping. Words are found with the browser’s word segmenter, which also splits Korean, Japanese and Chinese text.

Example

With the input lines apple, 10, banana, 6 and cherry, 3 on an 800 × 533 image, the largest size is 107 px (20% of 533), so apple is drawn at 107 px, banana at 107 × √0.6 ≈ 83 px and cherry at 107 × √0.3 ≈ 59 px, all three placed around the centre.
