UseVelyoPDF Privacy Scanner

Pre-send document review

Check a PDF Before Sending It

Before a PDF leaves your device, review more than the visible pages. Use a local, read-only scan to identify supported metadata, hidden-text, annotation, attachment, JavaScript, and redaction-risk signals that deserve a closer look.

Scan a PDF locally

The scan runs locally in your browser. Your PDF is not uploaded to the UseVelyo compression API or an external document-processing service.

How to review a PDF before sharing

Choose an authorized PDF, run the browser-local scan, and review each reported category before deciding whether the document is ready to send.

This is a diagnostic aid, not a safety guarantee. It scans supported patterns and may miss unsupported PDF structures.

An image-only scanned page may have no extractable text layer, so text-dependent checks are limited unless the PDF already contains OCR text.

Try a synthetic demo first

These small PDFs are generated in this page and contain no user data.

Local, read-only processing: the PDF is parsed in a browser worker. It is not uploaded, changed, converted to Base64, or sent to the compression API.
  1. Step 1

    Choose the exact file you plan to send

    Use the final authorized copy rather than an earlier draft or a document that may still change.

  2. Step 2

    Run the local privacy scan

    The PDF is processed in browser memory and is not sent to the compression API or an external document processor.

  3. Step 3

    Review and resolve each signal

    Check reported categories in context, return to the source application when removal is needed, and inspect the revised PDF again.

A Pre-Send Check Covers More Than the Visible Page

A document can look finished while still carrying document properties, review annotations, embedded attachments, or scripts. Those items may be intentional, but they should not travel to a recipient by accident. A pre-send scan creates a short review list before the file reaches a client, customer, colleague, filing system, or public download page.

The scanner reports supported signals rather than judging the document’s purpose. A metadata result means a property is present; it does not expose the property value. An annotation or embedded-content result means that structure exists and should be reviewed in an appropriate PDF application.

  • Confirm whether document properties should accompany the shared copy.
  • Look for comments, form-related content, attachments, and JavaScript that were not meant for the recipient.
  • Treat hidden-text and redaction findings as prompts for manual review, not automatic proof of disclosure.

Match the Review to Where the PDF Is Going

Emailing a draft to a trusted collaborator is different from publishing a final document or sending it outside your organization. Decide which properties and interactive features are appropriate for the destination before acting on the report. If the recipient needs comments or a form, their presence may be expected; if the file is a public copy, the same items may require removal.

Use the scan on the actual outbound file after export. Editing software can add creator, producer, date, annotation, or attachment structures during the final save, so a report from an earlier copy does not describe the version you are about to send.

What This Pre-Send Scan Cannot Decide

The tool does not decide whether visible names, addresses, account details, images, or page content are appropriate to share. It does not remove findings, certify compliance, or replace a document-review policy. Complex clipping masks and unusual graphics may also fall outside the supported patterns.

Pages without an extractable text layer may be scans or image-based pages. On those pages the tool cannot verify whether a visual redaction removed underlying information. Review the original workflow and use purpose-built redaction software when the report shows limited coverage.

Questions about this PDF check

Does the PDF get uploaded during the check?

No. The scan runs locally in your browser and does not send the PDF to the UseVelyo compression API or an external document-processing service.

Does a low-risk report mean the PDF is safe to send?

No. The report covers supported technical signals only. You must still review visible content, the recipient, your sharing policy, and any unsupported PDF structures.

Can the scanner remove metadata or comments?

No. It is read-only. Use an appropriate PDF editor or the source application to remove unwanted content, then review the exported file again.
