QR File Transfer怎么用
- Select File or Text on the sender: choose a file up to 5 MiB, or enter text and click Generate QR codes.
- Scan the entry QR on another device to open the lightweight receiver directly. No address entry or Receive tab is required.
- Enable the receiver camera and grant permission, then click Start sending on the sender and keep all animated QR codes in view.
- Wait for reception and verification to finish, then save the file. Received text is shown directly and can be copied or downloaded as TXT. Editing text stops the old transfer; generate new codes before sending again.

- Files are limited to 5 MiB. Text has the same 5 MiB limit measured in UTF-8 bytes, not characters. Speed depends on QR size, camera, lighting, and device performance; 100 KB/s is not guaranteed.
- The entry QR only opens the page. Enable its camera and keep scanning to receive data. Prepare offline reception on the receiving device while online first: an unprepared first visit cannot load the page without a connection.
- Received text preserves Chinese characters, emoji, line breaks, and spaces. Links do not open automatically and HTML is not executed. The tool does not provide encryption or sender authentication; use a trusted setting.

File and text encoding, camera processing, and reconstruction run in the current browser. Transfer contents are not uploaded to FreeTool. The initial load needs a connection. Complete offline preparation on the receiving device while online to use its dedicated receiver offline; prepare again if the browser clears its cache. QR codes are not encryption: anyone who can film the screen may receive the content.
