JSON Minification Savings Calculator
Quantify the saving from minifying and compressing JSON.
About JSON Minification Savings Calculator
Minification removes whitespace for roughly a fifth saving, but gzip does far more because JSON repeats key names constantly. With compression enabled, minification adds only a marginal further gain. Enabling compression on the server is a one-line change that saves far more than minifying, which is why it should always come first.
Formula
JSON Minification Savings
Minified = pretty × (1 − whitespace share); gzipped = minified × (1 − gzip saving)
- gzip on JSON
- Compresses extremely well because keys repeat, often by 85 to 90 per cent
Worked example
With the default values below, JSON Minification Savings Calculator returns Minified Size of 663.000. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits
- The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
- In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
- Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.
How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.
Frequently Asked Questions
How is JSON Minification Savings calculated?
Minified = pretty × (1 − whitespace share); gzipped = minified × (1 − gzip saving) Minification removes whitespace for roughly a fifth saving, but gzip does far more because JSON repeats key names constantly. With compression enabled, minification adds only a marginal further gain.
Why does JSON Minification Savings matter?
Enabling compression on the server is a one-line change that saves far more than minifying, which is why it should always come first.
