Pick random letters — single or batch.
Random Letter Generator picks one or more letters from A–Z using a cryptographically secure random source in your browser. Teachers use it for classroom games, designers use it for placeholder labels, and writers use it for prompt-based exercises. Choose how many letters to generate, whether to allow repeats, and copy the result with a single tap.
Open the page, enter the input you want to check, and the result appears immediately above — there is nothing to install, no account to create, and no popup to dismiss. Every Toolzer utility is designed to give you the answer on the first screen and let you copy or share it in one click. If the result looks unexpected, run the test a second time: transient network conditions, browser extensions, and corporate proxies can all affect single-shot measurements, and a fresh run usually confirms whether the issue is real or a one-off blip.
Every tool on Toolzer is built to work on desktop and mobile, including the latest versions of Chrome, Edge, Firefox, Safari, and Brave. Results are rendered directly in your browser whenever possible, so the page stays responsive even on slow connections. When a server lookup is required — for example to query public DNS, WHOIS, or geolocation databases — the request is proxied through Toolzer's edge so the third-party service never sees your IP address.
Toolzer is a privacy-first toolbox: the page is served as a static, minified bundle with long-lived cache headers, so repeat visits are essentially free for both you and our servers. Inputs you type — text to format, passwords to generate, URLs to inspect — stay on your device unless an explicit server lookup is required. We do not sell data, we do not run third-party advertising trackers, and we do not require an account to use any tool on the site.
It uses the browser's crypto.getRandomValues API, which is suitable for non-cryptographic randomness like games, prompts, and draws.
Yes — switch the case toggle to lowercase or mixed before generating.
Up to 100 in a single batch, which covers most classroom and brainstorming use cases.
No. Every utility on Toolzer is free, anonymous, and works in any modern browser without registration. You will never see a paywall or a forced sign-up flow — the goal is to give you the answer on the first screen and let you move on.
Yes. Whenever the tool can produce an answer entirely in the browser — password generation, JSON formatting, regex testing, hashing, text counting — the data never leaves your device. When a server lookup is unavoidable (DNS, WHOIS, geolocation), the request is proxied through Toolzer's edge so the upstream service never sees your real IP address.
Yes. The interface is fully responsive and works on iOS Safari, Android Chrome, Samsung Internet, and every other up-to-date mobile browser. You can pin the page to your home screen for one-tap access.
Yes. Every Toolzer page has a clean, permanent URL you can bookmark, share, or paste into a ticket. Results are generated client-side on each visit, so the link always shows fresh data instead of a stale screenshot.
