Choose image settings for speed and visual quality
Start with a moderate quality setting, compare the result at its intended display size, and compress only as far as the image remains clear. Keep descriptive filenames, width and height attributes, useful alt text and an original backup. Browser support and available memory can limit very large conversions.
How these tools are maintained
GrowthSparx reviews the formulas, instructions and examples for clarity. Tool outputs are estimates or implementation aids and should be checked against your analytics, business rules and platform policies. No account is required; tools described as browser-based process their inputs on the device unless the page clearly states otherwise.
