How It Works
Using the PDF Tools — Merge & Split takes only a few steps. Select Merge or Extract Pages mode. Upload one or more PDF files. For extract: enter page numbers (e.g. 1,3,5-7). Download the resulting PDF instantly. The tool updates results in real time as you adjust inputs, so you can experiment quickly without reloading the page.
Under the hood, PDF manipulation uses pdf-lib: PDFDocument.load() merges pages via copyPages(); extract filters page indices before save(). Ranburg implements this logic with modern browser APIs and tested algorithms so results are consistent across Chrome, Firefox, Safari, and Edge. Advanced options are available when you need finer control over formatting, encoding, or calculation parameters.
For productivity tools workflows, the PDF Tools — Merge & Split integrates naturally with other Ranburg utilities in the Business Tools category. Copy output with one click, paste into your CMS, IDE, spreadsheet, or Salesforce org, and continue your work.
