THE NUMBERS, EXPLAINED
How to use this calculator.
Preserves aspect ratio without upscaling; dimensions round downward to positive integer pixels. Byte size uses your measured average, so upload count is an aggregate lower bound, not a file-packing guarantee.
Start with your inputs
Enter portfolio image widths (pixels), portfolio image heights (pixels), maximum export long edge (pixels), estimated bytes per exported pixel, upload batch byte limit (bytes). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Portfolio image widths (pixels) | 4000,2000 |
| Portfolio image heights (pixels) | 3000,1000 |
| Maximum export long edge (pixels) | 1000 |
| Estimated bytes per exported pixel | 0.5 |
| Upload batch byte limit (bytes) | 500000 |
A worked example
With the example inputs above, export dimensions by image (pixels) is 1000×750, 1000×500. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Export dimensions by image (pixels) | 1000×750, 1000×500 |
| Estimated export bytes | 625,000 |
| Minimum byte-capacity upload batches | 2 |
How this is calculated
Export dimensions by image (pixels)
Scale each image so its longest edge fits the limit.
Estimated export bytes
Multiply exported pixel counts by estimated bytes per pixel.
Minimum byte-capacity upload batches
Divide aggregate estimated bytes by batch capacity and round up.
Symbols and units
- a
- Portfolio image widths (pixels)
- b
- Portfolio image heights (pixels)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Preserves aspect ratio without upscaling; dimensions round downward to positive integer pixels. Byte size uses your measured average, so upload count is an aggregate lower bound, not a file-packing guarantee.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Export dimensions by image (pixels); Estimated export bytes; Minimum byte-capacity upload batches. The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Preserves aspect ratio without upscaling; dimensions round downward to positive integer pixels. Byte size uses your measured average, so upload count is an aggregate lower bound, not a file-packing guarantee.
Are my inputs stored or sent to AI?
Calculations on this page happen in your browser. The separate AI question finder sends its submitted conversation to OpenAI; these calculator fields are not sent. Favourites and recent tool names are stored locally. A shared link contains the inputs you choose to include.
