Word Cloud Generator

Word Cloud Generator

Paste text or a weighted word list and get a downloadable word cloud, rendered entirely in your browser — nothing is uploaded.

Input modes

• Analyze text: paste any article or notes. English words are counted case-insensitively; Chinese runs are segmented with the browser's built-in ICU dictionary (Intl.Segmenter), so real words like 中国 come out instead of fragments. Add custom phrases to force multi-word terms (for example 机器学习), and extra stop words to hide noisy tokens.
• Word list: one entry per line as word, weight. The weight is optional — word weight, word: weight, and bare words all work. Lines starting with # are comments. This mode is a good target for data exported from other tools.

Layout and appearance

• Shapes: circle, square, and star. Words are placed along a spiral from the center, biggest first, with a small padding between neighbors.
• Size scale: logarithmic, square-root, or linear mapping from word weight to font size — use sqrt or log when a few dominant words would otherwise flatten the rest.
• Rotation ratio, four color palettes, transparent / white / dark background, and sans or mono fonts.
• Image mask: enable it and pick a PNG cutout to fill its transparency, or a dark-on-white silhouette image (logo, map, animal shape). Words then only occupy the image's area. The threshold slider controls how much of the image counts.

Output

The preview paints at 2x resolution; Download PNG saves the 1920×1200 image. Shuffle layout re-places the same words with a new random seed for a different arrangement. The status line shows how many words were placed, how many were dropped (did not fit), and the render time.

Everything runs locally: your text and mask images never leave the browser.
