Metadata & annotationsReview before sharing

Preserve standard metadataTitle, author, subject and standard fields from the first PDF when available. Create a cleaned copyDoes not copy standard metadata and removes the accessible XMP block. Remove comments and annotations on exportRemoves notes, highlights and other annotations from the rebuilt copy.

Keep linksKeep fields

Important limitCleanup is not a forensic guarantee. Removing annotations can also delete useful review comments: keep the original.

05

OCRLocal Tesseract recognition

LanguageScope

OCR can take time. Language data is downloaded on first use, but the PDF stays in the browser.

The searchable PDF is a rasterized copy with an OCR text layer; forms, interactive links and digital signatures are not preserved.

06

PDF accessibilityLocal preflight before PDF/UA review

Pre-check, not certificationWorkToolset checks automatable signals. Actual reading order, contrast, color and editorial meaning still require human review.

If the working copy is unchanged, analysis uses the source PDF to preserve its tags. After edits, it analyzes the rebuilt copy as it would be exported.

07

RedactDraw directly on the preview

Masking mode activeDrag on the page to create a black area. Masks stay attached to their page even if you reorder it.

Rasterization quality

Permanent in redacted exportRedaction rasterizes pages: selectable text, links and forms are removed from that output.

CompressFrom the working copy

LevelInternal images

Visual compression: output is rasterized. This is mainly useful for scans and image-heavy PDFs.
