What Deckle's verification receipt checks (and what it doesn't)
By DeckleUpdated
After every tool runs, Deckle reopens the new file on your device and checks it before you download it. The result screen shows a Verification receipt with one "Verified:" line of measured facts, such as "24 pages inspected · 100% of selectable text kept", and Detailed checks listing each check and its outcome. The receipt tells you what was measured. It is a useful second look, not a certificate, so still open the result and look at the pages that matter.

Content and sharing requirements still need inspection
A passed check is not independent certification
How to read the receipt
- Run a tool, for example Organize PDF pages, and wait for the result screen.
- Read the headline. It states what the tool did, such as "8 pages turned" or "Password required to open".
- Read the "Verified:" line under Verification receipt. Each fact is separated by a dot.
- Open Detailed checks to see every check, its outcome and any measured value.
- Open Receipt details for the engine and verifier versions and how long the run took. It also reads "Local checks; no independent attestation."
- Download the result and look at it yourself.
What the facts mean
| Fact on the "Verified:" line | What was measured |
|---|---|
| "24 pages inspected" | The new file reopened and had that many pages |
| "98% of selectable text kept" | Text extracted from the result compared with text from the source |
| "99% visual match on the worst page" | Rendered pages compared with the originals; the lowest score is shown |
| "no selectable text to compare" | The pages are images, such as scans, so text could not be compared |
| "source pages unavailable to compare" | The comparison could not run, and is not counted as a pass |
| "3 selected items removed" | Remove PDF metadata reopened the new file and found none of the items you ticked |
| "3 of 3 output files checked" | Every file a tool produced was reopened |
The receipt colour follows the checks: green when they passed, amber when a check warned, grey when something could not be compared. An advisory check is marked "(advisory)" when it reports a difference that is expected for the job.
What the receipt does not tell you
- That the pages are in the order you wanted. A page count can be right while two pages are swapped. Look through the result.
- That a scan was read correctly. "No selectable text to compare" means there was no text to check, not that the text is fine.
- That the file is private. A receipt for Merge PDFs does not mean the author name or attachments were removed. Use Remove PDF metadata for that.
- That other readers will display it the same way. The checks use Deckle's own reader on your device.
- That a digital signature is still valid. Any rewrite invalidates a signature on the new copy.
- Anything about the document's content being correct, complete or suitable for its recipient.
What the receipt contains, and what it does not
The record Deckle keeps for each run notes which tool ran, what it measured and the software versions. It does not contain your page text, your passwords or a copy of the file. It stays in your browser with the document.
When a check fails
If a check fails in a way that means the result is wrong, the result is discarded and the error card says so: "The result failed its checks and was discarded. Your original is intact." Change the settings or the file and run the tool again. If a check is advisory, the result is kept and the difference is reported so you can decide.
Tips
- Read the numbers, not just the colour. "92% visual match" is a pass for some jobs and a reason to look closer for others.
- Look at pages around each change. After removing or moving pages, check the pages either side.
- Check scans by eye. When the line says "no selectable text to compare", page through the result.
- Keep the original until you have checked the result. Deckle never changes it.
Frequently asked questions
Does a green receipt mean the PDF is perfect?
No. It means the checks that ran passed. It does not cover page order, the meaning of the content, or how another app displays the file.
Are the checks done on a server?
No. Deckle reopens and measures the result in your browser on your device.
Why does my scan say "no selectable text to compare"?
The pages are images with no text layer, so there was no text to compare. Deckle reports that rather than claiming a pass.
Can I show the receipt to someone as proof?
It is a record of local checks, labelled "no independent attestation". It shows what Deckle measured, not a certified statement about the document.
