Shrink any PDF below 100KB by re-rendering pages at a lower DPI / quality — privately, in your browser, with exact target sizing.
A 100KB ceiling is common for strict government forms. Shrink44 reaches it by re-rendering each page at a controlled DPI and JPEG quality.
For very small targets, single-page documents work best — a tiny budget spread across many pages forces low quality.
