A visible binding workflow
The queue is the document.
The first row becomes the first section of the result. Drag whole files into place, or use the labelled arrow controls from a keyboard, before creating anything.
Set the binding order
Move entire documents by drag and drop or by focusable up and down buttons. The numbered rail shows the final sequence.
Merge and download
The browser copies every page into one PDF, preserves the chosen order, and gives you a single local download.
What the result preserves
Different paper can share one binding.
Portrait, landscape, A4, Letter, and custom-sized pages keep their existing dimensions. Dismerge PDF copies PDF pages instead of turning them into screenshots.
File and page order retainedFiles follow the numbered queue; pages stay in order within each file.
Mixed page geometry retainedPage dimensions and rotations are copied into the combined PDF.
Source bytes stay localReading, ordering, merging, and download preparation happen in this browser tab.
Merge PDF FAQ
Before you bind the files.
How many PDFs can I merge?
You can combine up to 20 PDFs, provided the full queue stays at or below 200 MB and 2,000 pages. At least two files are required.
Can I reorder files without a mouse?
Yes. Tab to the Move up or Move down button on any file row and activate it with Enter or Space. Screen readers announce the new position.
What happens to mixed page sizes?
They remain mixed. The merger copies each page with its existing width, height, and rotation rather than resizing every page to a common sheet.
Are bookmarks, forms, and signatures preserved?
Page content is copied, but document-level bookmarks, attachments, form structures, and other features may be omitted. Combining signed PDFs normally invalidates their signatures.
Why can a large merge fail?
Browser memory varies by device. Even within the published limits, a complex PDF can need substantial memory. Try fewer files or close other tabs if the browser stops the job.
Are my PDFs uploaded?
No. This tool has no file-upload endpoint. Your browser reads the source files and builds the download locally on your device.
