How to pick the right PDF tool
Most instant.tw PDF tools run entirely in your browser using open-source libraries (pdf-lib, pdfjs-dist) — your file is never uploaded to a server. A few conversions that need a full document-rendering engine (like PDF ↔ Word/Excel/PowerPoint) run on a secure Pro server instead, and those pages say so explicitly.
If you're not sure which tool you need:
| You want to… | Use |
|---|---|
| Combine several PDFs into one | PDF Merger |
| Pull specific pages out | PDF Splitter |
| Get a scanned PDF under a size limit | Compress to Exact Size |
| Make a scanned PDF searchable | PDF OCR |
| Edit an editable Word version | PDF to Word |
