Merge PDF for authors
Updated July 2026
Arthize lets authors and self-publishers merge PDF files in a private workspace — free, with no watermark. Merging PDFs combines several documents — and any JPG or PNG pages — into one file losslessly, so text stays selectable and images stay sharp.
Why authors merge PDF files
An author merges manuscript chapters into one file, resizes the pages to the print trim size, and exports a clean, watermark-free PDF for the printer.
Built for manuscripts. Whether it's manuscripts, proofs, cover files, Arthize's merge pdf keeps the work inside your private workspace. Unpublished manuscripts are valuable IP; private processing keeps them off public servers.
What matters when you merge PDF files
A proper merge is lossless because it copies existing page objects instead of re-rendering them.
You can reorder individual pages, not just whole files, before merging.
Merging never adds a watermark, even on the free plan.
