Can someone else see the password I generate?

No. The Password Generator uses the browser's Web Crypto API. The value only exists in your tab's memory until you copy it somewhere safe.

Are the QR codes I generate trackable?

No. SwiftTooly's QR codes encode your raw URL directly. There's no redirect through our domain and no scan analytics — anyone who scans goes straight to the destination.

Which UUID versions are supported?

RFC-4122 version 4 (random) by default, with the option to generate version 7 (time-ordered) for database-friendly inserts.

Do the generated values expire?

No. Static QR codes, passwords and UUIDs never expire — they last as long as you need them.

Free Online Generators

Create QR codes, passwords and UUIDs that never leave your device.

Your files never leave your device. No upload. No sign-up.

Generators are the last category where uploading your input makes any sense — yet most free generators online still send your URL, password seed or UUID request to a server. SwiftTooly generates QR codes, passwords and UUIDs directly inside your browser using the Web Crypto API and well-known libraries. The output appears in the same tab that requested it, with no detour through anyone else's infrastructure.

Why use SwiftTooly's generators

Cryptographic randomness

Passwords and UUIDs come from crypto.getRandomValues — true browser-grade entropy.

Never logged

Generated values are not stored, transmitted or replayed. Refresh and they're gone.

Customizable output

Choose QR size and color, password length and character set, UUID format and bulk count.

No watermarks

QR codes are clean PNGs — no branding pixel, no scan-tracking redirect.

Browser-based vs upload-to-server

SwiftTooly (browser)

QR codes, passwords and UUIDs are generated by JavaScript inside the tab. Nothing about the value or how often you generate it leaves your device.

Typical upload-to-server tools

Server-side generators see every URL you encode and every password you produce, often log them, and sometimes route QR scans through their own tracker.
