Try the public sample files
Compare Word appearance, inspect Excel cells, and see the effect of compression. Examples include real inputs, outputs, and measurements. Downloading them requires no account and does not use your allowance.
Conversion and editing
PDF to Word and PDF to Excel require different choices. Preserved appearance, editable text, and spreadsheet cells are not the same thing. Read the guides and the comparison with downloadable files.
Organization, sharing, and OCR
Learn to combine pages, handle signatures, reduce files for sharing, and review recognized text. The instructions explain consequences a success message alone does not show.
Images, privacy, and evidence
Compare exploratory AI analysis results and see a metadata cleanup example. The studies include methods and limitations: they do not certify authenticity, universal accuracy, or undetectability.
