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.
你们会把我的文件上传到服务器吗？+
不会——这里的每个工具都完全在你的设备上处理文件，不会向服务器上传任何内容。唯一的例外是 AI 工具，它们会把提取的文本（而非文件本身）发送给 Claude 来完成工作。
有文件大小限制吗？+
我们没有人为设置限制，但由于处理过程在你的浏览器中进行，非常大的文件（超过 500MB 或 1000 页）会受到你设备内存的限制，而非我们的限制。
