Use Merge PDF - free
Frequently asked questions
How many PDFs can I merge at once?
There is no hard limit on the number of files. Very large batches (hundreds of pages) may slow down on older devices since all processing happens in your browser, but for typical use there is no restriction.
Will the quality of my PDFs be affected?
No. pdf-lib stitches pages together directly without re-rendering any content, so text sharpness, image resolution, and embedded fonts are all preserved exactly as in the originals.
Can I reorder the files before merging?
Yes - after dropping your files you can drag them into any order before clicking Merge. You can also remove individual files from the list if you change your mind.
