Frequently Asked Questions
I have 1099s from five different brokers. Can I merge them all?
Yes — there is no limit on the number of PDFs you can merge in MiOffice. Add all your broker 1099s, arrange them in any order, and merge into one file. Options traders with 200–300 page 1099-Bs can combine everything without hitting any size cap.
Will my SSN and account numbers be safe when merging?
Yes. MiOffice processes everything privately — your files are never shared or stored. This is critical for tax documents, which contain your SSN, brokerage account numbers, and full income breakdown.
Does the merged PDF preserve all pages and form data?
Yes. The merge preserves every page, image, and text layer from each source PDF. The only change is combining them into one file — no content is removed or reordered unless you choose to drag and reorder pages before merging.
