Image maths stay local.

Image to Base64
Encode file bytes to Base64 in your browser.
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.
