Is the QR Code generated on the server?

No. Generation happens in the browser. None of the content is sent to an Ontoom server.

Which content types can I use?

URL, free text, Wi-Fi, email, phone and WhatsApp, with color, margin and error correction options.

Which error correction level should I choose?

Medium (15%) is usually enough. Use High or Maximum if the QR will be printed on material that may scratch or cover parts of the code.

Can I download PNG and SVG?

Yes. PNG is ideal for quick sharing; SVG scales better for print.

How is it different from dynamic QR?

A static QR embeds the final content. A dynamic one points to an intermediate page with status (active, paused or expired) before redirecting.

Important: Test the QR Code before printing or publishing. Sensitive content stays only in your browser.

Need a campaign with editable destination and status? Dynamic QR Code.

Online QR Code generator

Create QR Codes in the browser for URL, text, Wi-Fi, email, phone and WhatsApp. Customize colors and margin, choose error correction and download as PNG or SVG — no account and no content upload.

QR Code for Wi-Fi, WhatsApp and URL

URL opens the link on scan. Wi-Fi builds the network payload so the phone can connect without typing the password. WhatsApp opens the app with the number (and optional message). Pick the right type in the generator above.

How to generate and download

Choose the content type and fill in the fields.
Adjust colors, margin and error correction if needed.
Download as PNG (sharing) or SVG (print/scale).
For campaigns with status, use the dynamic QR.

PNG vs SVG

PNG is handy for chats, slides and social. SVG stays sharp at any size — better for posters, packaging and print.
