Always keep the original — the safe Redact PDF workflow

A small habit that saves headaches later. This guide shows the safe Redact PDF workflow that always preserves the source file before any edit.

Tool:Redact PDF

If you've ended up here, you have a PDF and a specific job: preserving the original. The defaults most software ships with aren't tuned for that — they're tuned for "archive everything at maximum quality," which is the opposite of what you need now.

Launch the tool: Redact PDF — Browser-only. Nothing is sent to a server.

Why preserving the original needs different settings

A PDF for preserving the original optimises for things the original PDF doesn't care about: small enough to upload quickly, compatible with whatever software the recipient is using, and free of embedded metadata that could leak personal information. The defaults give you the opposite — large, high-quality, metadata-rich. Useful for some jobs, wrong for this one.

The workflow with Redact PDF

  1. Open Redact PDF in any modern browser.
  2. Drop the PDF on the input area.
  3. Choose settings appropriate for preserving the original — see the recommendations in the next section.
  4. Run the processing. It happens locally in your browser tab.
  5. Download and verify. Quick visual check before you send.

What to verify before sending

Quick check-list once Redact PDF finishes:

  • Open the result. Make sure it looks right at the size the recipient will actually see it.
  • Check the file size. Match it against the limit you're targeting.
  • Confirm the file extension. Sometimes you need to rename — for example, a recipient who expects .jpg won't necessarily accept .jpeg.
  • Send a test to yourself first. Open the test on the same device the recipient will use, if you can.

Frequently asked questions

Can I undo the compression later?

No — compression is one-way. Always keep the original PDF archived somewhere, and treat the compressed version as a send-only copy.

Is Redact PDF safe for sensitive PDFs like a resume or visa documents?

Yes — every step happens locally in your browser. The PDF never leaves your device because there is no server in the loop.

Will Redact PDF work for a batch of PDFs?

Yes — drop multiple files at once. All of them get the same preserving the original settings applied, then downloaded as a folder.

What if the recipient asks for the original?

Keep the original. Redact PDF produces a copy; the source file you dragged in is never modified.
