Gzip Estimator

Estimates the compressed size of text content (HTML, CSS, JS, JSON) using gzip and Brotli compression, showing the compression ratio and how much bandwidth the compressed version saves.

• →Paste your raw text (or upload a file) into the input area to calculate its compressed size.
• →Compare the gzip and Brotli results — Brotli typically achieves 15–20% better compression than gzip.
• →Use the Content-Type selector to apply realistic whitespace-removal (minification hint) before estimating.
• →Check the savings percentage to decide whether enabling compression on this asset is worth it.
