How local PDF processing differs by task
Not every PDF operation changes a document in the same way. Merging, splitting, rotating, extracting and page organization generally copy or adjust existing PDF page structures. Compression and secure redaction rebuild affected pages as images, which can remove selectable text, links or form fields. PDF to Markdown extracts text but simplifies complex layouts. FlowPDF explains these trade-offs on each tool page so you can choose the appropriate operation.
