Send a 10 GB File Online: Size and Browser Checks

A 10 GB video can fit in a HexaTransfer transfer, but check its exact size and the receiving browser first. The current allowance is 50 GiB, or 53,687,091,200 bytes across all selected files. A decimal 10 GB file contains 10,000,000,000 bytes; the units are different.

Check what actually fits

The allowance applies to the combined size, not to each file separately. A video with project sources, subtitles and still images can exceed the allowance even if the video alone fits. Check file properties and the total shown in the tool. There is also a limit of 1,000 files.

If the total is too large, prepare separate, clearly named deliveries or reduce the export size if the recipient agrees. A ZIP may do little to shrink an already compressed video. A single archive is mainly useful for preserving a folder structure.

The essential check: saving to disk

To receive a file this large, the browser must support direct-to-disk saving through File System Access / showSaveFilePicker. Without it, HexaTransfer refuses to download any file above 512 MiB. Downloading all files as a ZIP is also blocked when its estimated size, including archive headers, exceeds that threshold.

This guard avoids trying to hold a huge download in memory. Having more RAM does not remove it. Ask the recipient to check their browser and try a non-sensitive file before the delivery; a recent browser does not guarantee this capability on every operating system.

Check free space at the chosen destination too. If the recipient needs to extract an archive, allow space for both the archive and its extracted contents. Downloading a set of small files individually can avoid the in-memory ZIP limit; it cannot make a single 10 GB file fit that limit.

Send the video or archive

1. Open the tool, add the file and check the total.
2. Choose the availability period in whole days using the selector, set a password in the options if needed, then start uploading. No account or email address is requested.
3. Keep the tab open and the device awake until the final confirmation. Completion time depends on factors including upload bandwidth and device performance; there is no fixed delivery time.
4. Copy the complete link and tell the recipient its expiry date.
5. On receipt, choose the save location offered by the browser and wait for saving to finish before opening the file.

Files are encrypted in the browser with AES-256-GCM. The key sits after # in the link and is not sent to HexaTransfer. Do not shorten the link by removing that part or post it in a public space.

Plan for a failed or late delivery

Network requests may be retried while the tab remains open. Uploading cannot resume after closing or reloading the page. Keep the original so you can start again if needed.

Choose 1–30 days, with 14 days by default, from transfer creation rather than the first download. The final screen shows the exact date. A download limit set during upload can end access earlier. A temporary transfer link is not a backup.

See the general upload walkthrough or WeTransfer alternatives by size and deadline.
