Add PDF Version

Hash + metadata is saved to localStorage · Max 20 versions

You haven't added a version yet. Upload a PDF to start the history.
💡 How it works? Saves your PDF file's hash + metadata to your browser's localStorage. The PDF file NEVER reaches our servers — it stays only in your browser.

Use cases:
• Contract lawyer: Save v1, v2, v3, v4 of the contract you're negotiating, track who changed what.
• Academic: Keep and compare different versions of your thesis drafts.
• Designer: Archive the development stages of your presentation PDF.

⚠️ Limitation: localStorage is ~5-10 MB per browser. Only metadata (hash + size + page count) is stored, not the PDF files themselves. For sentence/word-level diff, use PDF Diff Pro.
Your files are encrypted with SSL and automatically deleted from our servers 7 days after processing.

Frequently asked questions

No. This tool does not analyze the internal layers of a single PDF; it is a ledger that compares the hash/size/page count metadata of different PDF files you uploaded separately over time.
