QR Code Generator — frequently asked questions
Do these QR codes expire?+
No. The QR code encodes your content directly — there is no redirect or tracking link — so it works forever and offline.
Is my data tracked?+
No. The code is generated in your browser and the content is never sent to a server. There is no analytics on the code.
PNG or SVG?+
PNG for putting into a document or email. SVG for print or anywhere it needs to scale to a large size without blurring.
How much text fits in a QR code?+
Up to a few thousand characters, but smaller is better — long content makes a dense code that is harder to scan. For links, keep the URL short.
你們會把我的檔案上傳到伺服器嗎？+
不會——這裡的每個工具都完全在你的裝置上處理檔案，不會向伺服器上傳任何內容。唯一的例外是 AI 工具，它們會把擷取的文字（而非檔案本身）傳送給 Claude 來完成工作。
有檔案大小限制嗎？+
我們沒有人為設下限制，但由於處理過程在你的瀏覽器中進行，非常大的檔案（超過 500MB 或 1000 頁）會受你裝置記憶體的限制，而非我們的限制。
