One PDF up to 50 MB and 200 pages.
Yes. PDF rendering and editing are performed 100% locally inside your browser. No document data is sent to an external server or cloud during splitting or merging, so confidential documents can be handled safely.
Split supports one PDF up to 50 MB and 200 pages. Merge supports up to 20 files, 50 MB each, 150 MB total, and 500 output pages. These safety limits prevent sudden browser memory growth.
After adding files one by one or all at once, grab the dotted handle icon on the left side of each file in the list and drag it up or down. This changes the order used in the merged PDF.
Use it when you need to merge multiple PDFs or split selected pages into a new PDF file.
