Frequently Asked Questions Before Reaching Out
Many common questions and pairing situations can be resolved immediately:
Why cannot my two devices connect or pair?
Make sure both devices have active internet access to exchange initial WebRTC handshake signals. If you are on an office, campus, or public Wi-Fi network with client isolation enabled, pairing may be blocked; trying a mobile hotspot or entering the 6-letter pairing code manually often establishes the link.
Are files uploaded or stored on any server?
Never. iFileSender utilizes peer-to-peer WebRTC DataChannels. Files stream directly between your devices without intermediate cloud storage, hard drive caching, or server inspections.
Is there any file size limit or compression?
There are no artificial file size limits and zero compression. High-resolution photos, 4K videos, zip files, and documents transfer in 100% original quality chunked through browser memory.
Can I transfer files between iPhone and PC without cables?
Yes! Simply open ifilesender.com on both your iPhone and PC browser, scan the pairing QR code, and send photos or videos directly without iTunes or third-party software.
Your email is used only to reply to your inquiry. We never send unsolicited newsletters or marketing material.
