Frequently Asked Questions
Is it safe to compress my tax documents online?
Yes. MiOffice processes everything privately — your files are never shared or stored. The FBI Denver field office has warned taxpayers about uploading sensitive documents to online PDF tools. MiOffice eliminates that risk entirely.
Why do I need to compress my tax PDFs?
Many CPA client portals, IRS e-file platforms, and email services have file size limits of 5–10 MB. A 1099-B from an active trading year can easily exceed 50 MB. Compression brings it within limits without removing any data.
Will compressing my tax PDF affect its legal validity?
No. Compression reduces image resolution and file overhead — it does not alter the text content, form fields, or embedded data. The compressed PDF remains a valid copy of your tax document.
