Merge PDF for tax preparers
Updated July 2026
Arthize lets tax professionals 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 tax preparers merge PDF files
A tax preparer merges the return with its schedules and supporting documents into one client file, extracts figures from a PDF form into a worksheet, and password-protects the final package.
Built for tax returns. Whether it's tax returns, W-2s and 1099s, schedules, Arthize's merge pdf keeps the work inside your private workspace. Returns contain Social Security numbers and income data; private processing and deletion are essential.
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.
