Are MyToolsBag's QR codes free to use commercially?

Yes. QR codes generated with MyToolsBag are free for personal and commercial use with no attribution required.

How much data can a single QR code hold?

At the highest capacity: about 2,953 bytes of raw binary, 4,296 alphanumeric characters or 7,089 pure digits. Long URLs work best when shortened first — smaller codes scan faster.

Should I download PNG or SVG?

SVG scales to any size without blurring — best for print and large formats. PNG is fine for on-screen use and social posts where a fixed pixel size works.

What resolution do I need for print?

At least 300 DPI. Better still, use the SVG and let your print software rasterize at the exact final size to keep the pattern razor-sharp.

Does changing the color affect scanning?

Yes. Keep strong contrast — a dark pattern on a light background — and avoid inverting the code (light on dark) since many scanners still struggle with inverted codes.

How do I test a QR code before printing thousands?

Scan it with two different phones (iOS Camera app and an Android device) from the expected distance. If both scan on the first try in normal light, you're safe to print.

How do I create a WiFi QR code?

Choose the WiFi type, enter your network name (SSID), password and security type (WPA/WPA2 for most routers), then download the code. Scanning it prompts phones to join the network automatically — no typing the password.

Is it safe to put my WiFi password in a QR code?

The code is generated entirely in your browser, so the password is never sent to MyToolsBag. Anyone who can see the printed code can join the network though — use a guest network for public spaces.

WiFi QR Code Generator

Pick the WiFi type above to create a WiFi QR code your guests can scan to join your network — no typing a 20-character password out loud. Enter the network name (SSID), the password and the security type (WPA/WPA2 for almost every modern router, or "None" for an open network), then download the code as PNG or SVG.

Scanning it opens a "Join network?" prompt on both iOS and Android. Print it for a café counter, an Airbnb welcome sheet, an office reception desk or the back of a router. The code is static and never expires, and because it's generated entirely in your browser your WiFi password is never sent anywhere. Change the password later and you'll simply need to generate a fresh code.

Frequently asked questions

Are these QR codes free to use commercially?

Yes. QR codes generated with MyToolsBag are free to use for personal and commercial projects with no attribution required.

Do the QR codes expire?

No. Static QR codes never expire — the data is encoded directly into the pattern, so they work forever as long as the linked content is still online.

What size and format should I download?

Use SVG for print (infinite scaling) and PNG for web and screens. For print at large sizes, generate at 1000px or export as SVG.

Can I add a logo without breaking the QR code?

Yes — set error correction to H (High) before adding a logo. High correction lets the code stay scannable even when up to ~30% is obscured.
