Size Tiers
Select based on total size. Multiple files are bundled automatically.
1 MB = 1,024 KB. File format matters greatly — a Word doc with images is much larger than plain text.

| Lite | 500 KB | An entire book in plain text, or a small PDF. | $7 |
| Plus | 5 MB | PDFs, code repositories, illustrated documents, contracts. | $14 |
| Pro | 25 MB | High-res designs, RAW photos, larger project bundles. | $30 |
| Max | 100 MB | Video clips, full project archives, media packages. | $58 |
