Canva can make QR codes, but the generator lives inside the Canva editor, so you need a Canva account and a design open just to get a code. A browser-based QR generator needs no account and no editor: it encodes your link directly into a static code with no added branding, and the code never expires.
Canva offers two flavors of QR code: a basic app that generates a standard static code, and a newer dynamic QR feature whose codes route through Canva so the destination can be changed later; by Canva’s own help pages the dynamic codes carry a Canva logo by default on most plans, with logo removal tied to higher tiers. Either way you are signing in and working inside a design editor. A standalone static generator skips all of that: your URL is encoded straight into the QR image, in your browser, with nothing in the middle.
A static local code is the better fit when you want a plain, permanent code for a flyer, menu, business card or slide: no logo you did not choose, no account, and no dependence on a third-party redirect staying live. The destination link is also never sent anywhere, since the code is generated on your device. To be fair, if you expect to change the destination after printing, a dynamic code is genuinely the feature you are signing up for.
No. The code is a plain, standard QR that encodes your link directly, with no branding added.
No. The generator works immediately in your browser with no sign-up.
No. A static code encodes the link permanently, which is why it never expires. If you need an editable destination, that requires a dynamic QR service.
