Questions
- Are my files uploaded anywhere?
- No. The file is read from your disk by the browser and processed in this tab using JavaScript and WebAssembly. Nothing is transmitted, which you can verify by opening your browser's network panel or by disconnecting from the internet — the tool keeps working.
- How do I make a WiFi QR code?
- Enter WIFI:T:WPA;S:YourNetwork;P:YourPassword;; as the content. Phones recognise the format and offer to join the network directly.
- Which error correction level should I choose?
- M is fine for screens. Go to Q or H if the code will be printed, stuck on something that might get scuffed, or have a logo placed over the middle — higher levels can lose up to 30% of the code and still scan.
- Why download SVG?
- It is vector, so it stays perfectly sharp at any size. A PNG scaled up to poster size will show soft edges that make scanning less reliable.
