Proof that a photo came from a verified device and hasn't changed since.
Proofwide certifies photos at the moment they are taken, on a device verified as genuine at that exact moment. Anyone who receives the image can check both facts in seconds, even after it has been forwarded, shared, downloaded or re-compressed.

What it does
One certificate, two guarantees.
Captured on a verified device
A certificate is only issued when the photo is taken inside the Proofwide app on a genuine, unmodified device, checked at the moment of capture. Files imported from elsewhere, screenshots and emulators are never certified.
Certified at capture
Certification happens the moment the shutter fires, before anyone has a chance to edit the image.
Checked by anyone
Recipients check an image in seconds, in the Proofwide app or on our verification page. No account is needed.
Shows where it changed
If an image has been edited, Proofwide marks the altered areas, so a reviewer sees exactly what to question.
Holds up after sharing
Messaging apps, email and web uploads resize and re-compress files as a matter of course. The certificate is built to survive that journey, however far the photo travels. That is the "wide" in Proofwide.
Private by design
Your photo is sent to Proofwide once, to be certified, and is not kept: no copy, not even a thumbnail. What remains on our servers is a small encrypted certificate record from which a direct reconstruction of the image is infeasible.
How it works
From capture to a verified answer in three steps.
-
Verified device · Certified 09:12
Capture
The photo is taken in the Proofwide app. The app confirms that the device is genuine, then certifies the photo on the spot.

Share
The photo is sent the way people already send photos. Resizing and re-compression along the way are expected.

Whoever receives the photo checks it in the Proofwide app or on our verification page and gets one of four answers.

No certification reportNo readable Proofwide certificate: either the photo was never certified, or its certificate was cropped or damaged beyond reading. Proofwide makes no statement about it, in either direction.
What Proofwide does not do. It confirms that an image came from a verified device and is unchanged since capture. It does not judge whether what the image shows is true.
Where it's used
Wherever a decision rests on a photo someone else took.
- Insurance claims Damage photos from policyholders, checked before a claim is settled.
- Returns and warranty Condition photos passed between customer, retailer and manufacturer.
- Vehicle rental and car sharing Check-out and check-in photos that settle damage disputes.
- Property handovers Move-in and move-out condition records for landlords and tenants.
- Deliveries and logistics Proof of delivery and of the condition of goods on arrival.
- Construction and inspections Site documentation that has to hold up months or years later.
- Second-hand marketplaces Listing photos a buyer can trust to show the actual item.
- Journalism and fact-checking Images with a verifiable record of where they came from.
- Legal and compliance Photographic evidence with a clear chain from capture to review.
In every case the person deciding was not there when the photo was taken. Proofwide gives them two facts they can rely on: a genuine device took it, and nobody changed it afterwards.
