How to merge/split PDFs online — free
Merge PDFs: upload multiple PDF files, reorder them with the Up/Down buttons, then click Merge into one PDF.
Split a PDF: upload one PDF file, choose "One file per page" or enter a custom page range (e.g. 1-3, 5, 8-10), then click Split PDF.
Download the result: download each file individually or all of them as a .zip.
The tool runs directly in your browser using the pdf-lib library, copying the original PDF page content
(crisp text, images, vectors) into the new file without re-rendering it as an image — preserving 100%
quality with very fast processing. Your files are never uploaded to any server.
Frequently asked questions
How many PDF files can I merge at once?
No limit on the number of files — you just need at least 2 to merge. You can reorder files with the Up/Down buttons before merging.
What split modes are available?
Two modes: "One file per page" splits the whole PDF into individual page files, or "By page range" lets you enter custom ranges like 1-3, 5, 8-10 to split into the parts you want.
Does this affect the quality of the PDF content?
No. The tool copies the original PDF pages (text, images, vectors) directly into the new file without re-rendering them as images, so quality is preserved 100%.
Are my PDF files uploaded to a server?
No. Merging and splitting happen entirely in your browser using the pdf-lib library — your files never leave your device.
Does the tool support password-protected PDFs?
Not currently — remove the password before uploading.
