Frequently Asked Questions

The estimates are theoretical maximums based on the connection speed. Actual download times may vary due to network congestion, server limitations, protocol overhead, and other factors. Consider these as minimum best-case scenarios.
For optimal customer experience, aim for under 100MB for downloads on mobile (4G). For larger files up to 500MB, consider using resumable downloads. Files over 2GB are best delivered via cloud storage links rather than direct download.
Each platform has different infrastructure costs and technical constraints. Gumroad offers 16GB because they use CDN storage, while smaller platforms limit sizes to manage bandwidth costs and ensure reliable delivery.
For PDFs, use optimization tools to compress images. For videos, use H.264 or H.265 encoding with appropriate bitrates. For audio, MP3 at 192kbps is usually sufficient. For software, use efficient compression like ZIP or 7z.
Design for 4G/LTE (20 Mbps) as your baseline - this covers most mobile users. Ensure good experience at 3G speeds (1 Mbps) for essential content. Your fastest users will always be happy, but optimizing for the middle 80% is key.
Yes, especially for mobile customers. Large downloads can consume significant data from customer plans. Always show file sizes clearly before download so customers know what to expect.
