Using Image Pixel Budget Planner
Fit image dimensions within a maximum megapixel budget without upscaling.
- Enter source width, source height, pixel budget using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Source width: 6000 pixels Source height: 4000 pixels Pixel budget: 4 megapixels Target width · pixels: 2449 Target height · pixels: 1632 Target megapixels: 3.996768 Scale · percent: 40.824829
Questions & answers
What does Image Pixel Budget Planner calculate?
Fit image dimensions within a maximum megapixel budget without upscaling.
Which units should I enter?
Source width uses pixels. Source height uses pixels. Pixel budget uses megapixels. Convert values to these units before calculating.
Which formula does it use?
Scale = min(1, √(budget/source pixels)); output dimensions round down.
What does the included example show?
Source width: 6000 pixels; Source height: 4000 pixels; Pixel budget: 4 megapixels. Result: Target width · pixels = 2449; Target height · pixels = 1632; Target megapixels = 3.996768; Scale · percent = 40.824829.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
