Generate beautiful, scannable QR codes and barcodes in seconds. Custom colors, embedded logos, vCard, WiFi, and bulk CSV processing — every code is built in your browser, so your URLs, passwords, and contact info never reach a server.
Most QR generators upload your text or WiFi password to a server before drawing the code. OhMyQR doesn't. Every QR and barcode is rendered locally in the browser tab you already have open. There is no signup, no watermark, no usage cap, and the code is yours forever — there's no expiring redirect that someone else controls.
Pick the dot shape, corner style, and colors. Drop in a logo for branded codes. Upload a CSV and get back a ZIP of up to 1,000 QR codes or barcodes — perfect for product labels, ticket batches, table cards, or any inventory workflow.
Sensitive data — WiFi passwords, contact details, internal URLs — is processed entirely in your browser. Nothing is sent to ohmyqr.app. You can verify this by opening your browser's Network tab while you generate a code: there are no outbound requests for the content you type.
