What is an invisible forensic watermark?

An invisible forensic watermark is a mark embedded in a file so it is not meant to be noticed in ordinary viewing. You assign a private identifier such as a person, company, deal, or recipient, and Markedfile embeds that mark in a copy you can share. If that copy later appears, detection looks for the mark that belongs to the identifier.

What does Markedfile store?

File contents are processed in memory and not stored. Your account keeps the metadata needed to detect a mark later: the identifier you assigned, the file name and type, the status, and timestamps. A file stays detectable while active. Deleting the record ends detection and frees the slot.

What is included in Free, and when does a file expire?

Free is the Personal Workspace plan with 5 active files. Each stays detectable for 6 calendar months from the time you mark it. Deleting the record ends detection and frees a slot immediately. This is a cap on active files, not a monthly upload quota.

Is there a free trial?

Starter, Pro, and Business plans include a 14-day free trial that requires a card to start. You can cancel anytime during the trial and will not be charged. The first charge comes after the trial ends.

How do personal plans differ from a business workspace?

Starter and Pro are for one person. Business and Enterprise add a shared workspace. Invitations and new marks in a shared workspace need an active Business or Enterprise plan.

Overview

Screenshot of the Markedfile homepage — What markedfile.com looks like

Markedfile embeds invisible forensic watermarks in files you share privately. You upload a file, assign a private identifier such as a person, company, or deal, and download a marked copy to share. If that copy later appears elsewhere, you can upload it to Markedfile to detect the surviving mark and trace it back to the identifier you assigned. The service supports images, PDFs, text files, Office documents, and video. File contents are processed in memory and not stored; only metadata needed for detection is kept.
