FAQ
Will merging damage the quality of my original files?
No. Merging is lossless β it directly concatenates page objects from the source PDFs. Text, images, and vector content all remain exactly as they were, with no recompression or re-encoding.
How many PDFs can I merge at once?
There is no hard limit; the main constraint is browser memory. Merging a dozen regular-sized files works fine. For very large files, consider merging in batches.
Can I change the file order before merging?
Yes. Each file in the list has up and down move buttons. Arrange them in the desired page order before starting the merge.
Can I merge PDFs with different page sizes?
Yes. Merging preserves each file's original page dimensions. A4 and A3 pages can coexist in the same merged document, each keeping its original size.
