Drop all the PDFs onto the page at once, or click to pick them.
Drag to reorder — top to bottom is the final page order.
Press Merge. The result saves straight back to your computer.
Your file never leaves this computer
This one runs inside your browser. The file is read into browser memory, processed there, and saved straight back to your disk — nothing is uploaded, and our servers never see it. Close the tab and nothing is left.
Want to check for yourself? Disconnect from the network first — this tool still works.
What it does — and what it doesn't
There is no hard limit on the number of files, but they all have to fit in browser memory at once. Dozens of office documents are fine; several hundred megabytes of scans are safer in two batches.
Encrypted PDFs have to be unlocked first. A file with an open password cannot be read in — use Password protect to remove it.
Bookmarks and form fields are not carried over. If you need a table of contents, rebuild it afterwards with PDF bookmarks.
Page sizes stay as they are; A4 mixed with B5 stays mixed.
Common questions
Does merging recompress anything?
No. Page content is copied across as-is — text stays text, images stay the original images, and nothing loses quality. The result is roughly the sum of the inputs.
Can I merge only some pages?
Yes. Load the file, select the pages you want on the thumbnails, save them with Extract selected pages, then merge that. Still all local.
How do I fix the order afterwards?
Use Delete and reorder pages — also done in your browser.
