Verifying documents at scale?
DocuExprt verifies 50,000+ documents in days — tamper detection, 30+ government APIs, DigiLocker source verification, 99% accuracy.
The free document tampering checker for fraud teams
Forged payslips, edited bank statements and doctored certificates slip past manual checks every day. This free document tampering checker tells you instantly whether a PDF has been edited — inspecting metadata and incremental-save history, running Error Level Analysis on images, and flagging font, overlay and object anomalies — and returns a clear tamper risk score. Run one document free, then unlock the full forensic report, bulk checking and document-type-specific deep checks with a free account. Powered by DocuExprt's CERT-IN certified, RBI & DPDP-compliant verification platform.
How to read your score
What your result actually means
Behind the risk score, every document comes back as one of four results. They describe how much evidence of change we found — not how serious that change was, and not whether anyone did anything wrong.
Not Modified
No meaningful evidence the document changed after it was created. On this evidence, it stands.
Possibly Modified
Faint, circumstantial traces — the kind ordinary handling leaves. Usually benign.
Likely Modified
At least one substantive trace of change. Read the findings before you rely on the document.
Modified
Evidence strong enough to conclude the document was changed. Ask the issuer for the original.
“Modified” does not mean “fraudulent”
Documents change for entirely legitimate reasons. Someone opens a PDF to fill in a field. A stamp is added. A file is re-saved to email it. This analysis reports evidence of change — it does not judge intent, and it cannot tell an innocent edit from a dishonest one. That is why every result carries its findings with it: the verdict tells you how much we found, the findings tell you what it was.
Examination
22 forensic checks across six areas
A document is not just what it displays. Underneath, it carries a record of how it was made, what software touched it, how its text is positioned, and how its pictures were compressed. Forgery is easy on the surface and hard underneath — which is where we look.
Digital signatures
Broken seals, signatures that were stripped out, and signature fields nobody ever filled.
Origin & authoring history
PDF editing tools, certificates drawn in graphic design software, and timestamps that disagree.
Internal structure
Accumulated save layers from repeated editing, and executable code embedded in the file.
Typography
The same typeface embedded twice in two different ways — the fingerprint of a second tool.
Page content & layout
Text sitting over other text, pages rebuilt from screenshots, typing added on top of a scan, stamps covering content, and invisible text.
Image forensics
Compression that stops matching itself, content spliced in from another picture, editing-software traces, and capture dates that conflict.
We also publish what we deliberately do not flag — OCR text layers, PDF compressors, signing layers and missing camera data — along with how findings are weighed into a verdict, what our confidence figure really measures, and the limits of what this analysis can tell you.

Is the document tampering checker free?
Yes — upload one document and get an instant tamper risk score free with no signup. The full forensic report, bulk checks and document-type-specific analysis unlock with a free account.
How does it detect if a PDF was edited?
It inspects PDF metadata and incremental-save history, runs Error Level Analysis (ELA) on images, and flags font, overlay and object anomalies that indicate editing.
What documents can I check?
Any PDF or image — salary slips, bank statements, offer letters, certificates, invoices, ID documents and more. Type-specific deep checks are available with an account.
Is my document stored?
Metadata inspection runs in your browser. For the deep forensic report, files are processed securely by DocuExprt's CERT-IN certified, DPDP-compliant platform and not retained beyond the check.
What is a tamper risk score?
A 0–100 score summarising how likely a document has been edited or forged, with HIGH, MEDIUM or LOW banding and the specific signals that drove it.

Checking one document, or every application?
Fraud does not arrive one file at a time.
This page inspects a single upload. DocuExprt screens every incoming document automatically, flags the suspicious ones for review, and keeps an audit trail of what was checked and why.
