You upload a video, grab the link, send it to a friend — and three weeks later they click it and get a "file expired" page. Or worse: nobody told you links could die, and an important share quietly went dark. Link lifespan is one of the most overlooked parts of video sharing, and every platform plays by different rules.

Here is what actually determines how long your video links live, and how to pick a service that matches how long you need them to work.

Why links expire at all

Storage and bandwidth cost money. Platforms that offer free sharing recover those costs by recycling old files: if nobody has watched a clip in months, keeping it costs more than deleting it. Expiry also protects uploaders — old links floating around the internet can outlive the purpose you shared them for.

The three retention models

Temporary links (hours to a week)

Transfer-style services (WeTransfer and similar) are built for one-shot delivery: the link works until it is downloaded a set number of times or a timer runs out, often around seven days. Perfect for sending a file once; useless as a permanent reference.

Activity-based retention

Some sharing sites keep files only while they stay "warm" — downloaded or viewed within a rolling window. A clip watched weekly lives indefinitely; a clip ignored for 30–90 days quietly disappears. You will rarely see this stated clearly; it surfaces as random dead links later.

Permanent hosting

Platforms designed for publishing rather than delivery keep links alive as long as the account is in good standing. Video-focused hosts like s.pub, which transcode uploads into adaptive streams and serve permanent watch pages, sit in this category — the link you share today is the link that works next year.

How to match retention to your use case

Quick share with a friend

Temporary links are fine — the video is watched once and forgotten. Just do not reuse the link later and expect it to work.

Portfolio or resume reel

This is where expiry hurts people. A demo video linked from a resume or email signature must outlive the job hunt — months at minimum. Use permanent hosting only, and test the link quarterly.

Client delivery

Somewhere in between: the client needs days to weeks, but the raw cut should not live forever. Temporary links are actually the responsible default here — set them to expire after the review window closes.

Making links last: practical habits

Read the retention policy before relying on a link

If a service does not clearly say links are permanent, assume they are not. Search their help pages for "expiry" and "retention" before committing.

Keep the original file

The one rule that makes expiry harmless: the platform is a delivery layer, never an archive. Whatever you share, keep the master on your own storage.

Prefer links with an expiry you control

The safest links are the ones whose lifetime you decide — expiring shares for sensitive material, permanent pages for public work. Services that expose this choice, including the link-first watch pages on s.pub, put you in control instead of a hidden cleanup job.

The short version

Temporary links serve one-time delivery, activity-based retention serves active content, and permanent hosting serves anything you will reference again. Know which one you are creating before you hit send — and the "file expired" surprise never happens to you again.
