FAQ

Yes — completely free, no sign-up, no watermark, and no export limits. Generated posters can be posted in any scenario such as home, shop, or exhibition.

No. The entire site is static; the QR code and poster are generated by JavaScript inside your browser, so the password is never sent to any server. Saved designs live only in this browser's localStorage and you can clear them at any time.

Three common reasons: the SSID or password has a typo (watch capitalization and full/half-width characters); the wrong security type is selected (home routers usually need WPA/WPA2); or some older Android cameras cannot read WiFi codes — use the system scanner or WeChat scan. On iOS the network must be in range and enabled.

Yes. To keep scannability, set error correction to Q or H, keep the logo under a quarter of the code area, and enable the white backing pad. Always test-scan the exported file.

For wall posters or reception signs, A5 or A4 at 300 DPI is recommended; desk tents 100×150mm; laminated cards can use the business-card size. Print at actual size (no scaling), and keep the QR at least 3×3cm — larger if people scan from farther away.

Yes. Tick "Hidden network" under WiFi info → advanced options; the payload includes H:true so the system actively searches for the hidden network when scanning.

The standard WiFi QR format does not support full enterprise EAP parameters, and compatibility across systems is poor. We suggest using the custom text/link mode to point the QR to an internal onboarding page.

SVG is a vector format that stays sharp when scaled, good for designers or print shops to re-edit; PDF is ready to print or send to a printer, with page size matching your paper settings. For WeChat or wall posting, PNG is enough.

Yes. The page does not depend on external scripts; after the first open the browser caches resources, so generation and export still work offline.

Yes. Name and save the current config under "My Designs" and load it anytime; you can also export a JSON config file to import on other devices or browsers.

Yes. Content you generate belongs to you and can be posted and distributed in commercial venues. However, do not generate QR codes containing others' brands, infringing content, or illegal use.

To keep the site free, we integrate third-party ads (Google AdSense). Ads are provided by third parties and unrelated to 365Lab. You can install an ad-blocker or manage personalized-ad preferences in Google's ad settings.
