The Core Difference: Pipeline vs Toolbox
PDF24 is a toolbox with 25+ individual tools. Great for occasional, single-file tasks — merge a PDF, compress a file, rotate pages. Simple and accessible.
DocInspector is a batch pipeline. If you have 50 contracts to repair, then sanitize metadata, then redact names, then encrypt, then watermark — DocInspector does all of that in one run. PDF24 would require you to visit 4 different tools and re-upload your files each time.
If you process documents in volume and care about security/compliance, DocInspector is purpose-built for your workflow.
