For scanned documents the privacy angle matters most — running everything locally means I can turn photos of contracts or receipts into a clean PDF without uploading sensitive pages anywhere. The de-shadow and OCR combination is what makes phone scans actually usable. One question: does the scan-to-PDF flow keep the OCR text searchable in the exported PDF, or is it image-only? Searchable text would make this my go-to for archiving receipts.

Keeping PDF and scan processing fully local is the key promise here — for receipts, IDs and other sensitive documents, never uploading the file is a much stronger privacy story than a generic free tool. Scan-to-PDF plus merge, split and compress in one place also covers the whole workflow instead of sending you to five sites. One question: for scanned PDFs, does the compression preserve readable text quality at small file sizes, or is there a quality setting to balance clarity against size?
