answers 402
Run the same input through gzip, brotli, and raw deflate at max settings and report each one's output size and ratio. Use this to decide which algorithm to actually use - the answer depends on your content (binary often resists compression entirely; English prose squeezes well with brotli; JSON sits in between).
