How to use these document guides
The document guides explain what each PDF and image tool on FinBizTools does, which settings matter and how to check the result before you send it. They are practical walk-throughs for common jobs: shrinking a scanned PDF to meet an upload limit, combining several statements into one file, extracting only the pages a form needs, turning phone photos of receipts into a single PDF, and converting PDF pages into images for a presentation or message.
All of these tools run inside your browser. Your files are processed in your device’s memory and are not uploaded to FinBizTools, which matters when you handle bank statements, identity documents or invoices. The guides also explain the trade-offs — for example, why heavy compression can make small print unreadable, or why converting a PDF to JPG turns selectable text into a picture.
