Frequently asked questions

Are your web utilities really free?
Yes, all six web utilities are fully free, with no watermark on favicons or QR codes and no signup required. The site is funded by Google AdSense advertising displayed in the margins, with no usage limit.
Is my data sent to your servers?
No. Every utility runs client-side in your browser. Generated passwords, converted colors or validated emails are never transmitted nor stored. The password generator uses crypto.getRandomValues for cryptographic entropy.
How do I generate a truly secure password?
Use the Password Generator, pick 16 characters or more with uppercase, digits and symbols. Generation is cryptographic (crypto.getRandomValues) and the password never leaves your browser, making it ideal for sensitive accounts.
Do the web utilities work on mobile?
Yes, every utility is responsive. You can generate a QR code, copy a password or test a color from your phone, then send the result via message or email without installing any app.

Why use our Web Utilities?

Building and maintaining a website or an online presence requires a varied toolbox. Generating a favicon optimized for different devices, creating a printable QR code, picking a coherent color palette, securing access with strong passwords, or validating an email address before a campaign — these operations come up constantly in everyday digital work.

Typical use cases are varied: a developer generating a multi-format favicon before a deployment, a shop owner creating a QR code that points to an online menu, a designer converting a HEX color to RGB for an export, a system admin generating a 24-character password, a marketer validating a list of emails before a campaign, or a developer detecting the screen resolution of a visitor.

These utilities target a broad audience: web developers, UI/UX designers, digital marketers, e-commerce owners, bloggers, freelancers and anyone managing a website, a blog or a professional account. The interface puts speed of use and clarity of results first.

SmartGap differentiators: every utility is free, with no watermark on favicons or QR codes and no signup. Passwords and computations run in your browser using crypto.getRandomValues, which guarantees that no sensitive data ever leaves your device.
