Frequently Asked Questions
I have tax exports from Coinbase, Binance, and Koinly. Can I merge them into one PDF?
Yes. PDF Merge accepts any number of PDFs and lets you arrange them in any order. Combine all your exchange exports and Koinly summaries into a single file for your CPA.
My 1099-DA has wallet addresses and transaction IDs. Is it safe to process this online?
With MiOffice, yes. MiOffice processes everything privately — your transaction data, wallet addresses, and trade history are never shared or stored.
Can I compress a 100-page Koinly export to email to my accountant?
Yes. PDF Compress reduces multi-page export PDFs by 40–70%. A 100-page Koinly report that is 15MB typically compresses to under 5MB — within Gmail and file-sharing limits.
