How to use this compress pdf to kb

How the result is calculated
The browser renders bounded pages into pixels, tests progressively lower JPEG quality and—only when needed—smaller page dimensions, then embeds one image per page. The result is image-only and may be well below the target; selectable text, links, forms, vectors and original metadata are not retained.
Read the current Mozilla PDF.js browser rendering examples before submitting.
All calculation and transformation work happens in this browser tab. No entered value is sent to an Noler Tools application server.
