Percentage calculator

Calculate a percentage of a value, increase or decrease a value, or recover a whole from a percentage.

How to use it

Open the tool and supply your image, text or values. Adjust the available settings, then inspect the preview or calculated result. Image and text workspaces let you choose a filename before Save or Share. File sharing depends on your browser; unsupported browsers use a download fallback.

Limits to know

To find the whole, the percentage must be nonzero. Inspect the selected operation before using the result.
