PDF tools

PDF tools handle the file-management tasks that come up constantly with documents: merging two PDFs into one, extracting specific pages, rotating mis-oriented scans, converting images to PDF or back. The toolset uses pdf-lib for editing and pdf.js for rendering, both standard libraries with well-documented behaviour around tricky cases like encrypted PDFs and complex annotations.

The PDF merger combines multiple PDFs into one in a configurable order, with optional bookmarks for each source file. The PDF splitter extracts a range of pages into a new PDF, with bulk export-each-page mode for breaking a multi-page PDF into individual single-page files. The page rotator rotates specific pages by 90°, 180°, or 270° — useful for fixing scanner-orientation errors. The page deleter removes specific pages from a PDF without re-rendering the rest.

The image to PDF tool composes one or more images into a PDF document with configurable page size and orientation — useful for combining scanned receipts or photographs into a single attachable file. The PDF to images tool renders each PDF page as a PNG or JPG, useful for extracting figures or for producing image-only versions of documents (for OCR pipelines that don't accept PDF). All tools dynamic-import their libraries on first use (pdf-lib ~250 KB, pdf.js ~1 MB) so the page chunk stays small until you start working.
