Rasterize a Property Contract to Hide Text and Seal Alike
When you hand a copy of a contract to an agent or a lender, what you want is a document containing only what they need to see. Redact, then rasterize every page and rebuild the PDF, and neither the covered text nor the seal impression can be recovered.
All 12 pages rasterized
Price, address, and seal made unrecoverable before hand-off
Why This Takes Longer Than It Should
A property contract concentrates, in one document, the names, addresses, and birth dates of both parties, the property location, the sale price, and bank account details. Copies go to the agent, the lender, and the accountant — and each hand-off requires deciding what the recipient actually needs to see. The registered seal impression printed on the signature block adds a region that simple black-boxing doesn't adequately handle.
What's Actually At Risk Here
- ✓A seal impression can be copied as an image. If the recipient doesn't need it, hide it as carefully as you hide a name.
- ✓Price and property address readable together amounts to disclosing net worth. Narrow the visible range to each recipient's actual need.
- ✓Rasterizing every page and rebuilding the PDF leaves neither the covered text nor the seal recoverable.

- 1PDF Markup
Cover the sale price, property address, the other party's name and address, and the seal impression in opaque black
- 2PDF to Image
Export every page as an image — this is the step where the underlying text data is discarded
- 3Image to PDF
Rebuild the images into a single PDF ready to hand over
- 4Compress PDF
Compress the now-larger file down to something you can attach to an email
Where People Get Tripped Up
These catch people out even when the steps are followed correctly. Skimming them first saves a redo.
- Rasterizing removes text search. If the agent needs to search clauses, agree on the format beforehand.
- Rasterized files get large. Run PDF Compress before attaching to email.
- Contracts are documents whose originals matter. Treat the redacted version strictly as a copy and keep the original separately.
Frequently Asked Questions
- Why rasterize instead of just redacting?
- Prices, addresses, and names are embedded as text data. Blacking out only layers a shape on top, so a text extractor reads everything. Converting every page to an image and rebuilding the PDF means the text data no longer exists at all.
- Should I hide the seal impression too?
- If the recipient doesn't need it, yes. A seal impression can be copied as an image and pasted onto other documents. If you need to prove the document was sealed, keeping it may be the right call — decide per use.
- Doesn't rasterizing make the file much larger?
- It does — several times the original is common, which is why compression is the final step. Since legibility matters in a contract, keep the compression ratio modest and confirm the figures and clauses are still readable.
- Can the redacted version replace the original?
- No. Contracts are documents whose originals carry legal weight. Treat the redacted file strictly as a copy prepared for one recipient and keep the original separately. If a party requires the original, a redacted copy won't satisfy that.
