What Preview does on a Mac, in the browser for everyone else: load one or more PDFs, arrange their pages as thumbnails, then join, reorder, rotate, delete or extract pages and download the result. Everything runs client-side — your files never leave this tab.

Files

Drop PDF files here or click to browse — add as many as you need, in any order .pdf only · files are read locally, never uploaded

Pages

Pages appear here once a file is loaded. Drag a thumbnail to reorder; click to select, Shift-click for a range, Ctrl/Cmd-click to add one more.

Download

Loads the pages left in the tray, in tray order, into one new PDF.

Notes

  • Joining is just loading more than one file — every page lands in the tray in file order, and the download stitches the tray into a single PDF. Drag pages anywhere, including between files.
  • Extracting works the other way: select the pages you want, and Extract selected downloads just those as their own PDF, leaving the tray untouched.
  • Hover a page for a moment and a full-size preview opens beside it, turned the way the page is turned — useful when the thumbnail is too small to read.
  • Keyboard: Delete removes the selected pages, Ctrl/Cmd+A selects every page, Esc clears the selection. Deletions get a five-second Undo.
  • Everything runs client-side in this browser tab; files are read locally and never uploaded. Password-protected PDFs are not supported.
  • The output is rebuilt page by page, so interactive features that span a whole document (bookmarks, forms, signatures) may not survive the repackaging — check the result before relying on it. See the site terms.
Beta — an early build, so expect bugs and rough edges. Double-check its output before you rely on it, and tell me what’s broken — I keep improving the tools people actually use.
