Text, tables and images
Turn web pages and tables into Markdown, images into other formats, generate random strings, GUIDs and numbers, and format LinkedIn posts.
HTML to Markdown
Paste a copied web page - a Copilot page, a docs article, an email - or fetch a public URL, and get clean Markdown back with citation markers and interface chrome stripped out.
Markdown table editor
Paste a table from Excel, CSV, JSON, HTML, SQL, LaTeX, XML, MySQL output or a wiki, fix it in a grid, and take clean Markdown out.
Image converter
Convert images between PNG, JPEG, WebP and AVIF, with quality, resizing and a background for transparency. Runs in the browser - nothing is uploaded.
Random strings
Generate up to 10,000 random strings from digits, letters, symbols or your own characters, optionally all unique.
GUID generator
Generate random v4 or time-ordered v7 GUIDs, formatted the way your code or database expects.
Random numbers
Draw random whole numbers from a range, with repeats or each one unique like a lottery.
LinkedIn text formatter
Add bold, italic, underline and lists to a LinkedIn post, preview where 'see more' cuts it off, and copy it across.
Send to Markdown
A one-click bookmark for pages this app cannot fetch itself, because they only exist inside your signed-in browser session.
