Merge, Split & Organize PDFs

Put every PDF page in the right place.

Combine files, reorder pages, rotate, remove, or extract what you need. Your documents stay in this browser, and the finished PDF is checked before download.

A tidy document without the upload queue

Arrange the pages you need, then check the result.

Mallow PDF keeps the common jobs in one workspace and explains when a document needs a safer tool before it can be edited.

Merge and organize use the same page grid

Add several ordinary PDFs, then move their pages into one clear order. Rotate sideways scans or remove a page without rebuilding the batch from scratch.

Split by selecting the pages to keep

Select cards directly or enter a range such as 1-3, 6, 9-12. Export the selection as one PDF or as separate, consistently named page files.

Local means the document stays in this tab

PDF bytes, filenames, thumbnails, page hashes, and output files are not sent to an application server or stored as a work history. Reloading clears them.

Output Check is useful evidence, not a universal guarantee

Before download, the browser reopens the result and compares its page count, dimensions, rotation, order, and a small visual fingerprint. Check important documents again in the viewer or print workflow you will actually use.

Protected, interactive, and structured documents need special care

Password protection, signatures, forms, annotations, bookmarks, tagged structure, custom page labels, layers, attachments, active actions, and complex cross-page structures are not silently removed or rewritten. The workspace leaves that file unchanged; make a flattened local copy or choose an ordinary PDF before trying again.

Large batches depend on the browser’s memory

Start with fewer files if thumbnailing slows down or the browser warns about memory. Closing other large tabs can also help before trying the batch again.
