About Generators
Generate passwords, QR codes and HTML email signatures. The password and QR code generators run entirely in your browser. The email signature generator is different: it hosts the photo and logo you upload so that the signature keeps working in email clients.
2 of 3 tools here run entirely in your browser.
Passwords
Choose a length from 4 to 128 characters and which character sets to include: uppercase, lowercase, digits and symbols. A strength indicator shows how strong the result is, and you copy it with one click. It uses the Web Crypto API, and the password never leaves your device.
QR codes
Enter any text or URL and the QR code updates as you type. Download it as a PNG. A QR code can hold up to about 4,296 alphanumeric characters, but longer text makes a denser code that is harder to scan.
Email signatures
Fill in your details, add a photo and logo, optional social links and a call-to-action button, then pick one of 10 templates and copy the signature or its HTML into your email client. The output is table-based HTML with inline styles, the format that survives being pasted into signature editors. A free account only adds the ability to save signatures for later.
Frequently asked questions
Are the generated passwords sent anywhere?
No. The password generator runs in your browser and uses crypto.getRandomValues, so the password never leaves your device.
Do the generators need an account?
No. All three are free to use without signing up. A free account only lets you save email signatures.
What can I put in a QR code?
Any plain text, URL, email address, phone number or Wi-Fi credentials.
Is my uploaded signature photo deleted afterwards?
No. Signature photos and logos are not temporary, because email clients keep loading the image from its hosted URL for as long as you use the signature.
