IntegrityScan: Your free tool to verify the integrity of files, text, and web pages — right in your browser

With IntegrityScan, you can check in seconds whether a file, a piece of text, or a webpage has been modified, corrupted, or tampered with. Everything happens securely and privately, directly in your browser — your data is never sent to any external server.

What you can do:

🔍 Calculate a hash (SHA-1, SHA-256, SHA-384, or SHA-512) of any file or text you upload

✅ Compare the generated hash with a reference one to verify that the content is authentic and unaltered

🛡️ Verify RSA-PSS digital signatures using a public key — ideal for confirming the origin of signed documents or encrypted messages

🌐 Check the integrity of a webpage by simply entering its URL: the plugin securely fetches the content and displays its SHA-256 hash

📈 Analyze SEO reports or HTML code (snippets, meta tags, etc.) to ensure they haven’t been changed over time

📤 Export a complete report in JSON format with all your verification results — perfect for audits, backups, or sharing with colleagues

⚠️ Important note on URL usage:
Use this function only on public pages that you are authorized to access. Do not enter private, internal, login-protected, or paywalled URLs. In short, always comply with the website’s terms of use and robots policy.

Why it’s secure:

The files and text you upload stay only on your device
Hashing and verification run entirely offline, with no external connections
The only exception is the URL check: in that case, seoproof.org acts as a secure intermediary and does not store or log any content

Whether you’re an SEO specialist, a webmaster, a content auditor, or simply someone who wants to verify a file’s authenticity, IntegrityScan gives you full control — with zero compromise on privacy.

Get started now: select a file, paste some text, or enter a URL.

Integrity verification has never been this simple, fast, and secure.
