Markedfile

Forensic watermarking

Know which copy leaked.
Trace it back.

Markedfile is forensic watermarking. It places an invisible watermark on a file you share in private, then uses leak detection to read that mark on a copy or a screenshot. Leak tracing points back to the identifier you assigned, which is how document tracking, content protection, and data leak prevention start with the file itself. File contents are not stored.

How forensic watermarking works here

01

Mark a copy

Upload an image, PDF, or other supported file and assign a private identifier. Download the marked copy. That is the file you share.

02

Keep the record

The account stores the identifier, not the file. You can see each active mark and delete a record when you want the slot back.

03

Check a suspected copy

Upload a copy or a screenshot. Leak detection looks for a surviving mark. Recovery is best effort and depends on the file and what happened to it.

Personal files and business documents

Personal use

Creators and people sharing private images. A forensic trail on each recipient’s copy.

For personal use

Business use

Contracts, financials, decks, board materials, and pre-release designs. Collaboration uses Enterprise.

For business use

A private identifier, not a visible label

You name the person, the company, the deal, or the recipient. The mark is not the product name, and it is not meant to be noticed in ordinary viewing.

File contents are not stored

Bytes are processed in memory and are not written to disk. The account keeps the identifier, the file name and type, status, and timestamps, plus a detection token while the file is active.

Pricing

Prices are USD per month. Free, Pro, and Unlimited apply only to your Personal Workspace. Enterprise applies to one shared workspace, and a personal plan does not cover it. An active file is one whose mark can still be detected. This is a cap on active files, not a monthly upload quota.

Questions

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 — a person, a company, a deal, or a recipient — and Markedfile embeds that mark in a copy you can share. The mark is not the product name. If that copy later turns up, detection looks for the mark that belongs to the identifier.

What does Markedfile store?

File contents are processed in memory and are 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 detection token is kept only while the file is active. Stopping detection, deleting the record, or letting it expire removes that token. Passwords are stored as hashes.

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

Free is the Personal Workspace plan. It includes 5 active files. Each stays detectable for 6 calendar months from the time you mark it, clamped to the end of shorter months. Stopping detection or deleting the record frees a slot immediately. This is a cap on active files, not a monthly upload quota.

How do personal plans differ from a business workspace?

Free, Pro, and Unlimited apply only to your Personal Workspace. That workspace cannot be shared or invited into. Business collaboration uses a shared workspace on Enterprise. A personal plan does not grant files or invitations there. You can create a shared workspace without paying, so there is something to subscribe, but invitations and new marks on that workspace need an active Enterprise subscription. Enterprise is per workspace.

Will every screenshot or edited copy be identified?

No. Recovery is best effort, and the confidence score is a heuristic. Images can often survive a crop, a resize, or recompression, but a heavily edited copy may not resolve. Marks in text files and ZIP-based packages, including Office files, are fragile. Markedfile does not promise that every leaked copy can be traced.

Which files can be marked?

PNG, JPEG, and WebP images; PDFs, including detection from the rendered page rather than metadata alone; text files and ZIP-based packages, including Office files; and other binary files, which come back inside a marked ZIP. Uploads are limited to 20 MB. Images are limited to 16 megapixels. PDFs are limited to 200 pages, 4 million rendered pixels per page, and 32 million per file.
