Generate random whole numbers in any range, with or without repeats: dice rolls, lottery picks, and PINs, using your browser's cryptographic randomness.

Your number
—
Set a range and press Generate.
The smallest and largest numbers allowed, or one of the presets: a dice roll, two dice, 1–100, lottery 6 of 49, or a 4-digit PIN.
Generate up to 10,000 numbers at once, with or without repeats, sorted or in draw order.
Press Generate (or Again) and copy the numbers.
They come from your browser's cryptographic random number generator (crypto.getRandomValues), the same source used for passwords and keys, with rejection sampling so every number is exactly equally likely.
Each number can be drawn at most once, like drawing balls from a lottery machine, so you can't ask for more numbers than the range contains.
No. Everything runs in your browser.
Time
Add and subtract hours and minutes, find the time after or before a duration, or the time between two clock times, including overnight.
Health
Calculate your body mass index in metric or US units, see your WHO weight category on a scale, and the healthy weight range for your height.
Random
Pick random names or options from a list, shuffle a list into random order, or split it into random groups or teams, fairly.
PDF & Documents · Convert
Convert PDF pages to JPG, PNG, or WebP images right in your browser. Pick the resolution, convert every page or a range, and download them one by one or as a ZIP.
PDF & Documents · Convert
Extract selectable text from a PDF, page by page, and download it as a plain .txt file — no OCR, so it reads the PDF's own text layer.
PDF & Documents · Convert
Convert a PDF to Markdown: font size is used to guess headings, and bullet or numbered lines are kept as list items.
