Image maths stay local.
ImageToolMage
Image size calculator
Compute megapixels, aspect ratio and print size from dimensions you enter.
No invented DPI from the file unless you supply it. Base64 is a local transform.
Method
Megapixels = (width×height)/1e6. Aspect reduces by GCD. Base64 uses standard alphabet on file bytes.
Assumptions
- Deterministic arithmetic.
- Optional print DPI is user-supplied.
- No cloud image API.
Questions
Does this edit pixels?
The size tool is arithmetic. Base64 encodes bytes; it does not resample.
Is EXIF required?
No. These pilots do not require or strip EXIF unless you use the en-US metadata tool.
