Organize PDF

It is those four tools fused into one workspace, with the advantage that you can chain operations in any order without saving intermediate files. Drop two PDFs in, drag pages from both into a new sequence, rotate a few, delete a few, and save once. Doing the same thing with separate tools would require: merge first, save, open in reorder, save again, open in rotate, save, open in delete, save — four files and four uploads. Organize PDF skips all of that. The trade-off is a slightly heavier interface that can feel cluttered for simple jobs. For a single small change (delete one page, rotate one page), the individual tools are faster. For multi-step rearrangements, Organize PDF is the right pick.

Yes. Drop as many PDFs as you want into the loader and every page from every file appears in one thumbnail grid, color-coded by source file so you can tell where each page originated. Drag from any source into any position, and a single save produces one merged-and-organized result. There is no fixed limit on input files — the only ceiling is browser memory, which depends on the total size and image density of your PDFs. Five or six small documents work easily on any device; ten or more very large scans may slow down the thumbnail grid on phones. If thumbnails struggle, use Merge PDF first to combine, then load the merge into Organize PDF for the rearrangement.

Yes, by default. Each inserted page brings along its content stream, annotations, form fields, hyperlinks, and embedded fonts and images. The result is a fully merged PDF where pages keep their original behavior. There is one caveat: if two source PDFs contain form fields with the same name, only the first instance keeps its value, because PDF requires unique field names per document. To avoid that, flatten filled forms with the Flatten PDF tool before bringing them into Organize PDF, which converts field values to static text and removes the name conflict. Digital signatures on source pages will show as invalid after assembly, since the byte content of the new file is no longer identical to the signed original.

Outlines (bookmarks) are dropped from the output by default, because remapping them across multiple source files and a reordered destination is complex and error-prone. If you need an outline on the result, build one fresh using the Bookmarks editor tool after saving. For most use cases (assembling a clean delivery copy, reorganizing scans), the original outlines were not useful in the new structure anyway. Internal links between pages from the same source file are rewritten to point at the new positions and continue to work. Links from one source PDF to another do not exist; they were always within-document references, so inserting a page from PDF B into PDF A does not create new cross-document linkage.

Yes. The board keeps an undo/redo history for the current session — press Ctrl+Z (or Cmd+Z on Mac) to undo the last action, Ctrl+Y / Cmd+Shift+Z to redo. There is no fixed depth, so you can step back through many edits as long as the tab is open. The Reset button reverts the entire board to its initial state (with all source files loaded but unmodified). Original files in your filesystem are never touched — even if you save, the source files remain unchanged unless you explicitly overwrite them when saving the result. Closing the tab drops all history, but the source files are still on disk to reload. Treat the board as scratchpad and save only when you are happy with the assembly.

Roughly. The thumbnail grid is the slowest part, and Organize PDF has to render thumbnails for every page in every source file at once, so a multi-PDF session uses more memory than any single-purpose tool. On a typical laptop, working with a combined 200-300 pages from multiple sources is smooth. On phones, keep the total under 100 combined pages for best results. The save step (an in-browser PDF engine writing the output) is fast — typically under a second even for large documents — because the actual byte-stream copy is efficient. The bottleneck is always the live preview, not the file generation. If you hit a slowdown, close other tabs to free memory and try again.
