A few things to know.

Does this include every Stirling-PDF feature?

No. These tools are an independent, browser-only implementation of compatible PDF workflows. Server OCR, certificate signing, and permanent redaction are not included.

Will every PDF work?

Use valid PDFs with at most 500 pages. Use Decrypt PDF with the correct password before editing. Encrypted documents are not supported by the editing tools. Page copying and rearrangement may not preserve bookmarks or interactive forms; flatten filled forms first. Editing a digitally signed PDF invalidates its signature.

Does Optimize PDF always make files smaller?

No. It compacts PDF structure without reducing image quality. Already optimized PDFs may not shrink; in that case you receive the original file. It does not downsample scanned images.

Are my documents sent to a server?

No. Processing happens in this browser. Fonts and libraries may download from this website, but your documents stay on your device. Closing or reloading the page clears your current workspace.

How to edit or convert a PDF

Merge, split, rotate and crop PDFs online. Extract pages or text, add watermarks and convert files with browser-based PDF tools.

  1. Choose the specific PDF task, such as merging, splitting or extracting pages.
  2. Open the tool's page and follow its input requirements and settings.
  3. Follow the step-by-step guide on that page, then review the result and save it when the tool offers an export.

Before you use the result

  • Read the selected tool’s limits before adding input.
  • Use the specific conversion direction you need; similar names can produce different results.
