Free file transfer across your devices.

No—not to a JITPOMI cloud drive. SEYFR prepares a local shareable copy on the sender's device and saves the received files on the receiver's device. It transfers directly when possible. If that is not possible, a relay forwards the live transfer while its contents remain end-to-end encrypted. SEYFR does not create a hosted copy for later download. Read the SEYFR Privacy Policy.

No. You can send nearby or across the internet—for example, from a home computer to a phone using cellular data in another country. SEYFR finds a direct path when possible. If the networks block one, an end-to-end encrypted relay forwards the transfer instead. No router setup is required. See how SEYFR connects devices. See what happens when your network changes →

Yes. Your file is encrypted from the sending device to the receiving device, including when the transfer needs a relay. SEYFR checks downloaded data as it arrives so transfer errors can be detected, then saves it to your chosen destination. Share the QR code or transfer ticket only with the person who should receive the file. See the security details.

You choose what SEYFR handles. On the sending device, select the file or folder you want to share. The receiving platform supplies the available save location or options; iPhone and iPad offer Save to Photos or Save to Files in On My iPhone > Seyfr. SEYFR also checks every received folder path and rejects any path that tries to escape the permitted destination. Your operating system's file permissions still apply. See how the destination lock works.

No. Neither person needs a SEYFR account, email signup, phone number, or password. Both people need a compatible SEYFR app: one person selects the file, and the other scans or pastes the transfer ticket. Get SEYFR for your devices.

SEYFR does not set a fixed transfer-size cap. The practical limit comes from available storage, device and operating-system limits, and whether the connection stays available. Speed depends on both devices and their networks. See how to send a large video.

No. SEYFR sends the file you selected without resizing it, compressing it, or changing its format. The operating system controls which file representation is supplied to SEYFR. See how to transfer photos without cloud storage.

SEYFR is free to use today with no fixed application transfer-size cap or ad walls. Device, operating-system, storage, filesystem, and network limits still apply. If you find SEYFR useful, please consider making a donation to support our development. To improve connection availability across more network conditions, we plan to scale the service by purchasing a dedicated, private encrypted relay server. To support these ongoing relay and infrastructure hosting costs, we plan to introduce paid premium features in a future version (Version 3). Any future pricing or packaging will be explained before it applies.

Use SEYFR when you want to transfer the selected file, not add it to a conversation. Some messaging workflows may compress media, impose limits, or retain a chat copy. SEYFR does not intentionally recompress or convert the representation supplied by your device, requires no account, and does not upload it to a JITPOMI cloud drive. Get SEYFR for your devices.
