An informational planning tool
Upload Compass provides calculators and educational information for general planning. Results are estimates based on your inputs and the published model, not guarantees of transfer completion, service performance, data integrity, or suitability for a critical deadline.
Your decisions and data
You are responsible for choosing appropriate inputs, checking units and timezones, allowing for uncertainty, and verifying the result with the destination service. Keep independent backups. Do not rely on an estimate as the sole safeguard for an irreplaceable file, emergency process, contractual delivery, or other high-stakes operation.
Availability and corrections
The tools and content are provided as available and may be changed or withdrawn. We aim for accurate arithmetic and clear explanations, but errors can occur. To the extent permitted by applicable law, no warranty is made that the site is error-free, continuously available, or suitable for every purpose. Nothing here excludes rights or liabilities that cannot lawfully be excluded.
Third-party services
Links to documentation and other websites are provided for context. They do not imply endorsement, sponsorship, or control. Your use of an internet provider, backup product, video platform, or hosting service is subject to that service's own terms.
Use of the site
Use the site lawfully and do not attempt to disrupt it or misrepresent its estimates as measured performance. You may keep and share the calculation results you generate. The methodology explains what those results mean; the privacy page describes the current data-handling design.
