Encoding Speed Meter

The Encoding Speed Meter benchmarks how fast your browser encodes and decodes Base64 at several sizes, with all timings produced locally. It is for developers curious about Base64 performance on their device.

Encoding performance varies by browser and hardware. Measuring it locally gives real numbers for your environment rather than generic claims.

1. Run the benchmark.
2. The tool encodes and decodes Base64 at several sizes.
3. Review the timing results for each size.
4. Compare performance across the sizes tested.

• Encode and decode benchmarking
• Several payload sizes
• Local timing measurement
• Results in the browser

• Gauging Base64 performance on a specific device
• Comparing encode and decode speed across sizes
• Demonstrating how payload size affects timing
• Sanity-checking performance before processing large data

• Run the benchmark a few times and look at the trend rather than a single figure.
• Close other heavy tabs so background load does not skew timings.
• Remember these are browser results and do not predict server performance.

• Treating one run as definitive; timings vary with system load.
• Comparing results across very different devices as if equivalent.
• Assuming browser benchmarks reflect server-side performance.
