Certifying many things at once

A month-end, a photo campaign or a whole archive. What deserves a seal and what does not.

Updated on 13/08/2026

When people discover what certifying is for, the temptation is to seal everything. And although technically possible, it is rarely the best idea: certifying makes sense where a dispute over date or content could arise, and across most of an archive that dispute will never happen.

What is worth it

Worth sealingUsually unnecessary
What proves you gave notice in timeInternal working documentation
Field photos and evidenceDrafts and working versions
What supports a claimWhat already comes signed and dated by a third party
What may disappear at sourceCopies of something already sealed

Important

The last row on the right saves the most. Certifying a copy of something already certified adds nothing: the proof is in the original and travels with it.

When batching makes sense

  1. 1

    At the close of a period

    End of site, end of season, file closure. All together, same date.

  2. 2

    After a day in the field

    The day's photos and reports, on return, in a single batch.

  3. 3

    Before something changes

    If you know a website, catalogue or price is about to change.

  4. 4

    And on receiving an alert or a claim

    Whatever exists at that moment, sealed now: from then on everything gets disputed.

Watch out

What makes no sense is sealing the whole historical archive "just in case". Seal what could end in dispute; the rest only consumes and adds noise around what matters.

How to know it worked

That third point usually settles the question of whether it pays: the evidence does not expire with your relationship with the platform.

Worth knowing

Each certification is an action and consumes. Hence the list above: it is not a technical restriction, it is that sealing what nobody will dispute is money buying nothing.

Can I certify something old?

Yes, but it fixes today's date, not the original one. For old material it proves less than it seems.

What if the file changes afterwards?

It stops verifying, which is exactly the point.

Is it needed for what is already signed here?

No: the signature carries its own evidence.
