Compress PDF to 50KB
If upload caps had a default, 50KB would be it — government forms, exam applications and e-district portals reach for it constantly. The good news: 50KB is a workable budget. 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.

Why 50KB is everywhere
It is the compromise portals settled on: large enough for one verifiable scanned page or several typed pages, small enough to keep millions of submissions manageable. Meeting it well is a routine skill this tool automates.
What fits at what quality
A single clean scan fits at solid readable quality. Two scanned pages fit at working-copy quality. Typed multi-page documents barely notice the cap. Image-heavy files are the honest exception — the real size is always shown.
