Create text, URL, or Wi‑Fi QR codes entirely in your browser with a live preview and PNG or SVG download. Payloads stay on your device — the QR library is served same-origin from ConvertWiseHub static files, and nothing is uploaded for generation. Prefer plain text only (no HTML or scripts), keep text under 1,200 characters for reliable scanning, and avoid generating Wi‑Fi passwords on shared screens.
Yes. Codes are generated in your browser. The QR library loads from ConvertWiseHub’s own static files (same-origin). Your text, URL, or Wi‑Fi fields are not uploaded to ConvertWiseHub servers for generation.
Text / URL mode accepts plain strings and links up to 1,200 characters. Wi‑Fi mode builds a standard WIFI: payload from SSID, optional password, and encryption (WPA/WPA2, WEP, or None). HTML, scripts, and file uploads are not supported.
PNG is ideal for slides, messages, and print at a fixed pixel size. SVG scales cleanly in design tools and vector layouts. Both use the same high-contrast black-on-white modules.
Long payloads make denser modules that are harder to scan from a distance or on low-quality screens. Keeping text under 1,200 characters and using a larger size (512 or 1024) improves reliability.
Higher levels add redundancy so a damaged or partially covered code can still scan, at the cost of denser modules. M is a balanced default; use H when codes may be printed small or marked up.
No. ConvertWiseHub does not create short links, track scans, or rewrite destinations. The code encodes exactly the text or Wi‑Fi string you enter — there is no server-side redirect or scan analytics.
