Document recovery guide

Recover an unreadable PDF after ordinary OCR fails.

A PDF can open normally and still be unusable: selection returns nonsense, pages are images, columns read in the wrong order, or faint scans disappear. Start with a free readability check, then recover only the files that need deeper processing.

Public source and recovery preview

IRS Form W-4 public document

Review preview identifying recovered form regions and fields that still require checking

The W-4 case contains printed labels, checkboxes, blank fields and multiple visual regions. Plain text can surface words while losing which label belongs to which field. The recovery preview preserves review structure and flags relationships that cannot be inferred safely.

Provenance: IRS Form W-4 public document. Inspect the Atlas case.

Classify the failure before paying

Image-only: the page has no selectable text layer.
Broken text layer: copy and paste returns scrambled or missing characters.
Skew or low contrast: lines drift and faint marks vanish.
Mixed layout: columns, sidebars, forms or tables lose reading order.
Handwriting: fluent-looking OCR may still invent names or numbers.

Choose the smallest adequate recovery path

Use the free check to determine whether the file is image-only or structurally broken.
Use ordinary OCR when the page is clean, single-column and easy to verify.
Use DocUnlocked when layout, provenance and review flags matter.
Escalate to manual review when identity, legal, medical or financial decisions depend on exact characters.

What review-ready means

A review-ready package exposes Markdown, structured JSON, a source manifest, summary and explicit review flags. It does not certify the transcription. The source remains the authority, and uncertain fields must be checked against the page image.

Limits and failure modes

Encrypted or damaged containers may need repair before OCR.
Dense handwriting and strike-throughs can remain ambiguous.
A 200 MB / 200 page capacity path depends on the deployed signed-upload route; direct browser limits may be lower.
Cloud processing is used and human review remains required.

Questions about this workflow

Why does copy-paste fail when the PDF opens?

The visible page may be an image or may contain a damaged text layer whose character order does not match the page.

Should I run OCR again?

For a clean single-column scan, yes. Use deeper recovery when ordinary OCR loses structure, fields or reading order.

Does recovery guarantee exact text?

No. Outputs are prepared for human review and uncertain content remains flagged.
