Compress PDF to 20KB
20KB caps appear on the strictest application portals — usually for single-page supporting documents. A typed page fits comfortably; a clean scan can just about make it with visible compression. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

The 20KB reality check
Typed, digital single-pagers compress to 20KB with room to spare. A single scanned page lands around 20KB only at aggressive compression — readable but soft. Multi-page scans cannot honestly fit; split to the required page first.
Make the target easier to hit
Upload only the page the portal asks for (Split PDF), prefer the digital original over a scan when one exists, and let grayscale conversion shed color data that tight targets cannot afford.
