Password Generator

Generate a strong random password in your browser. You pick length and character sets; nothing is sent to PdfPeaks. Copy it into a password manager.

Runs in your browser — nothing is uploaded. Print or copy the result; there is no PDF export on calculators.

This generator draws a random string from the sets you enable: lowercase, uppercase, digits, and symbols. It uses the browser’s cryptographic random source. PdfPeaks never sees the result. Copy it into a password manager; this tab will not remember it after you leave. To put a password on a PDF, use Protect PDF instead.

Last verified 2026-08-29 — Uses crypto.getRandomValues only. No Math.random fallback. Length 8–64, default 20.

Guide

Free Password Generator — Random, In Your Browser

PdfPeaks Password Generator builds a random string from the character sets you enable: lowercase, uppercase, digits, and symbols. Length is a slider you control. The generator uses the browser’s cryptographic random source when it is available, not Math.random. The password is never sent to PdfPeaks; there is no account and no log. Use it when a site rejects a weak password or when you need a throwaway for a shared test account. Store the result in a password manager — this page does not save it after you leave.

How It Works

Length

Longer is stronger; 16+ is a sensible default.

Sets

Mix cases, digits, and symbols unless the site forbids them.

Generate

Each click is a new random draw in this tab.

Copy

Paste into the signup form or a password manager.

Common Use Cases

  • New accounts: One unique password per site.
  • Shared lab logins: Generate, share out of band, rotate later.
  • Passphrases: This tool is random characters, not a word list.
  • PDF lock: To encrypt a PDF, use Protect PDF instead.
  • Count a policy: Pair with Word & Character Counter if a form has a length cap.

Tips for Best Results

We cannot see what you generate. If you need to remove a password from a PDF you own, that is Unlock PDF.

Frequently Asked Questions

No. Generation happens in your browser. We do not log it.

When the browser provides crypto.getRandomValues, that is used. If it is missing, generation is refused rather than falling back to a weak RNG.

Sixteen or more characters with mixed sets is a reasonable default unless the site forbids it.

This only creates a string. Use Protect PDF to put a password on a file.

Enable at least one character set, keep length in range, and use a modern browser with a secure context (HTTPS).
