About Sheaf
Sheaf is a small kit of three PDF tools in one place: bind images into a PDF, merge and split existing PDFs, and view any PDF in a scroll or slide layout. Everything runs in your browser — nothing is uploaded to a server.
Features
- Bind any number of images into a PDF, in the order you choose
- Merge pages from multiple PDFs into one, reordered freely
- Split a document into page ranges, downloaded as separate files or a zip
- Rotate individual pages before binding, merging, or splitting
- View a PDF as a continuous scroll or as single sliding pages
- Zoom, keyboard arrows, and swipe navigation in the viewer
- Runs entirely in your browser, nothing is uploaded
How to use it
- Pick a tool at the top: Images → PDF, Merge & Split, or Viewer.
- Drop in your files, or tap the panel to browse for them.
- Drag the handle on any page to reorder it, or rotate and remove pages as needed.
- Use the action buttons to bind, merge, split, or open the viewer.
Frequently asked questions
Can I combine pages from more than one PDF?
Yes — add several PDFs in the Merge & Split tab and every page from every file lines up in one list that you can freely reorder before merging.
How does splitting work?
Enter page ranges like "1-3, 5, 7-9" based on the numbers shown in the page list. One range downloads as a single PDF; more than one range downloads as a zip with one file per range.
What's the difference between Scroll and Slide in the viewer?
Scroll lays every page out top to bottom in one continuous view. Slide shows one page at a time with next and previous controls, similar to a slideshow.
Can I navigate the viewer without a mouse?
In Slide mode, the left and right arrow keys move between pages, and on touch devices you can swipe left or right.
Is my data uploaded anywhere?
No. Every file stays in your browser and all processing happens locally; nothing is sent to a server.
